Roll

“ Roll′ing, modulating: moving on wheels: making a continuous sound.—ns. Roll′ing-mill, a place in which metal is made into sheets, bars, rails, or rods, by working it between pairs of rolls: a machine for rolling metal, &c., into any required form, or for crushing materials between rollers; Roll′ing-pin, a cylindrical piece of wood for rolling dough, paste, &c. to any required thickness; Roll′ing-press, a press of two cylinders for rolling or calendering cloth; Roll′ing-stock, the stock or store of locomotive-engines, carriages, &c. ”

“ I claim, 1st, The combination of the flexible painting or die printing roll with the supplying roller, for painting, graining, ornamenting pails, or other tapering articles.
2d, The mechanism for holding and revolving the pail, when mounted on a bench or table, in combination with the movable printing or die roll, operating substantially in the manner as and for the purposes set forth. ”

“ The roll is ready to make up into a ball, when it is in a soft mashy state, and when in the act of rolling it gives out juice freely. None of this juice must be lost, it must be mopped up into the roll, again and again in its passage up the table, and finally into the ball, when made up. ”

“ In addition to the eight rolls of paper already mentioned eight other rolls are in position, so that when any of the rolls run out the roll-carrier may be turned on a turntable, and the new roll of paper quickly pasted to the end of the depleted roll. ”

“ A cylinder, or roll, C, furnished with a series of steel knives, rotates in one of the divisions formed by the midfeather, and the floor of the trough in this division is inclined in such a manner as to cause the pulp, as it travels, to pass under the roll. Beneath the roll is the bed-plate, which is fitted with a series of steel knives c c similar to those on the exterior of the roll. ”

“ Never you mind!
Roll on!
Roll on, thou ball, roll on!
Through seas of inky air
Roll on!
It's true I've got no shirts to wear;
It's true my butcher's bill is due;
It's true my prospects all look blue—
But don't let that unsettle you!
Never you mind!
Roll on!
(It rolls on.) ”

“ Laying two or three Leaves upon one another, they roll up all together side-ways into a long Roll, yet leaving a little hollow. Round this they roll other Leaves one after another, in the same manner but close and hard, till the Roll be as big as ones Wrist, and two or three Feet in length. ”

“ In the case of plate-rolls, which are plain cylinders, this setting down must be equal at each end. The mass of the top roll is balanced, to avoid shock when a plate is entering. The rolls are made of cast iron, and are either grain rolls or chilled rolls. The first are formed from a tough strong grade of iron, the quality which is used for all the roughing down and general work. ”

“ The leaf is rolled by a line of men on each side of such a table (41⁄2 feet is a good width for it) passing up from man to man, from the bottom of the table to the top. The passage of each handful of roll from man to man is regulated by the man at the end, who, when the roll in his hand is ready (that is, rolled enough) , forms it into a tight compressed ball (a truncated shape is the most convenient) and puts it away on an adjacent stand. When he does this, the roll each man has passes up one step. ”

“ Both rollers and balls, and the paths on which they roll, therefore, are made of hard material; further, balls and rollers must all be exactly the same size in an individual bearing in order to distribute the load between the points or lines of contact as uniformly as possible. ”

“ When he had finished reading he rolled it back upon the umbilīcus, usually holding it under the chin and turning the cornua with both hands. In the case of a long roll this turning backward and forward took much time and patience and must have sadly soiled and damaged the roll itself. The early rolls were always long and heavy. There was theoretically no limit to the number of sheets that might be glued together, and consequently none to the size or length of the roll. ”

“ A is the roll in the carrier. The die is placed on the table or bed B. The roll is held against the die with a pressure of many tons, obtained by compound leverage. By means of the wheel, E, and the connecting pinion and rack, the bed, carrying with it the die, is moved back and forth under the roll. This is called "rocking" and by it the soft steel of the roll is forced into the die and a reverse impression of the design is obtained. The roll is then hardened and, by a reversal of the process, impressions from it are transferred to the steel plate from which the stamps are to be printed. ”

“ A representation of rolls arranged on the system which I have attempted to describe, occurs on a piece of sculpture (fig. 11) found at Neumagen near Trèves in the seventeenth century, among the ruins of a fortified camp attributed to Constantine the Great [87] . Two divisions, full of rolls, are shewn, [35] from which a man, presumably the librarian, is selecting one. The ends of the rolls are furnished with tickets.

The system of pigeon-holes terminated, in all probability, in a cornice. ”

“ You know that a bowl, if it had no bias, that is, if it had no little weight inside it tending to tilt it, would roll along the level bowling-green in a straight path, its speed getting less and less till it stopped. ”

“ It should have been stated that two workmen stand one at each side of the rollers, and as the dough is flattened out, they fold it up, or double one part upon another, so that the roller at its next passage squeezes these parts together, and forces them to mix. ”

“ Now, the step from a simple supporting roller to a fixed roller, or wheel, appears a very easy one. At least it appears very easy to us who are accustomed from childhood up to the action of the wheel. ”

“ Every day they are rebound tighter and tighter, the operator sitting on the ground with the cord twisted round a post, and winding and tightening with all his strength, till at length the roll has become compressed into a solid mass about an inch in diameter, and gradually tapering towards each end. ”

“ Roe, s. A species of deer; the female of the hart; the eggs of fish; that of the male fish is called the soft or melt; that of the female the hard or spawn.
Roller, s. Anything turning on its own axis, as a heavy stone to level walks; bandage; in saddling, the broad fillet, with two or more straps and buckles to secure the saddle or sheet.
Rollypooly, s. A corruption of roll ball into the pool, a sort of game, in which when a ball rolls into a certain place it wins. ”

“ If the top, when it has ceased spinning, does not roll without the circle, it must remain in the ring to be pegged at by the other boys, or he redeems it by putting in an inferior one, which is called a ‘Mull.’ When the top does not roll out, it is said to be ‘mulled.’” Mr. ”

“ A double set of rollers is kept on hand when possible, but it frequently happens that rollers collapse about as fast as they can be adjusted, and the paper is hung up till a new lot gets in, or till the weather cools off a bit. ”

“ They draw these plates between rollers to bring them to an even thickness all along and every plate of the same thickness, and it is very strange how the drawing it twice easily between the rollers will make it as hot as fire, yet cannot touch it. ”

“ There are at least four pairs of drawing-off rollers in a comb, and the fibres drawn off by each—be it noted continuously—are united to form a sliver which is passed through a revolving funnel into a can. ”

“ By turning the wheel any type can be brought to the front, and a stationary guide controls its descent as it makes the impression. An inking roller is seen on the right, which inks the faces of the type. ”

“ The innocent wavelets dancing in the sun, pretty and sparkling, and the huge black rollers, whose crests under the weight of a gale, before they can curl over and break, explode into spindrift, are propagated by the wind blowing obliquely on the surface of the water. ”

“ The fabric or goods to be operated upon being first wound tightly upon a roller, that roller is to be mounted upon an axle or pivot, bearing in arms or brackets at the back of the machine, as shown at D. From this roller the fabric a a a a is conducted between tension rails, and passed under the bed cylinder or paper bowl E, and from thence proceeds over a carrier roller F, and over steam boxes not shown in the drawing, or it may be conducted into a hot room, for the purpose of drying the colours. ”

“ At one side of the table is a row of large spindles, or rollers, on which the chenilles—cardings, is the factory word—are wound, and the dropping is so contrived that the ends of those which fall overlap the ends of the lengths on the spindles by about an inch. ”

“ Now put on your roller and drive it down to the hub and see that the roller is free from the fork. See that jewel pin reaches fork properly and that the guard pin also reaches the roller. See that your balance is free from the plate and the bridge. If the balance is true and all right, you are ready to put on your hair-spring. See that it is in beat. It is well to make a mark on the balance before taking off the old staff, showing positions of hair-spring stud and jewel pin. ”

“ Other rolling toys, such as wheels and hoops, whose motion is kept up by means of continuous striking, offer a very different kind of amusement. The violent running, combining as it does something of the zest of the chase with the pleasure of overcoming a difficulty, forms a delightful compound with the enjoyment of the rolling as such. ”

“ Advantages and Applicability of Rolling.—Rolling uses very much less power than drawing, because the friction against the fixed die in the latter process is very great. For much the same reason rolling proceeds much faster than drawing, and on both these accounts it is incomparably the cheaper of the two. ”

“ The roller takes as much tea as he can cover with both his hands, and places it on the mat in a sort of ball. He keeps them closely together, and rolls them from right to left; this motion gives each leaf a twist on itself, and rolls it so firmly that it retains the shape when dry. ”

“ The distance between the knives of the roll and the bed-plate is regulated by levelling screws, which are so adjusted that both ends of the roll are raised at the same time, which is a great improvement upon the older types of breaking engines in which only one end of the roll was raised, whereby the knives became unequally worn. ”

“ In ball bearings the load is concentrated at a few points, the points where the balls touch the race, and in the roller bearing at a few lines, the lines of contact between the rollers and the surfaces of the journal and bearing ”

“ In order to avoid the uneven wear of the top rollers, caused by the slubbing or roving passing through them at one point constantly, it has become the practice to give a slight lateral traverse to the guide bar. ”

“ The object of beating or rolling is to make the book as solid as possible. For beating, a stone or iron slab, used as a bed, and a heavy hammer, are necessary. The stone or iron must be perfectly smooth, and should be bedded with great solidity. ”

“ The awning is manipulated by pulling the rope which unwinds, causing the roller to revolve and releasing the rope allows the weight of the awning to make the roller revolve the reverse way, winding up the rope. ”

“ One of the more modern styles is on the principle of the wringer above described, or a series of rollers arranged around a central drum, and each having a rubber spring attached, by which means the clothes are not subjected to undue pressure at one or two points, as in the first mentioned kind. ”

“ The various factors governing the proper rolling are so numerous that it is necessary for each individual rolling mill to work out a practice that gives the best results upon the particular analysis of steel it makes. ”

“ Rollers, are also moveable pieces of wood, of the same figure, which are occasionally placed under planks, or long pieces of timber, in order to move them with greater facility either in the dock-yards, or in lading and delivering merchant-ships.
ROLLING, the motion by which a ship rocks from side-to side like a cradle, occasioned by the agitation of the waves. ”

“ The rollers may be a spring shade roller mounted in the ordinary way, or a roller with a spool and cord, identical in principle with the roller shown in Figure 150, and the bottom of the curtain is provided with snaps to hold it in place when down. ”

“ The fabric to be fluted and puffed is drawn between a pair of rollers moved by a crank, the rollers, where they approach each other, having flutes or grooves so arranged as by their pressure on the fabric as it passes between them to make the fluting and to flatten it. ”

“ The sheets are then placed between tins, and the whole passed |11| between the rollers, which are regulated by a screw, according to the thickness of sections and power required. The workman, technically called “Roller,” has to be very careful in passing his books through, that his hand be not drawn in as well, for accidents have from time to time occurred through the inattention of the Roller himself, or of the individual who has the pleasure of applying his strength to turning the handle. ”

“ For fine yarns the rollers cease to rotate slightly before the carriage has attained the end of its outward run, or stretch, and at such times all attenuation is due to the pull of the spindles upon the threads. ”

“ The wax having been spread on the flat bar, the roller, heated by being put into hot water, is then heavily pressed over it. The roller has two wood handles, so that considerable pressure may be given to it. ”

“ The principal business of rolling and slitting-mills, is rolling nail plates; they also serve to make nail rods, hoops, tires, sheet iron, and sheet copper. In this State we have not less than twelve. ”
