MACHINE FOR CRIMPING BOOK-LEAVES.
Specification of Letters Patent.
Patented Jan. 26, 1909.
Application filed. February 5, 1906, Serial No. 299,574. Renewed July 6, 1908. Serial No. 442,245.
To all whom it may concern:
Be it known that I, JOHN DAHLY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Crimping Book- Leaves, of which the following is a full, clear, and exact specification.
My invention relates more particularly to machines for crim ing the leaves of ledgers and other similar ooks of account, so as to render the same more flexible or pliable contiguous to the binding where they bend.
Heretofore it has been proposed to produce this result by running the leaf to be crimped between corrugated rolls, which produced a series of corrugations throughout a desirable portion of the width of the leaf and resulted in breaking the calendering or surface of the paper so as to make it more flexible at that place, the corrugations being lengthwise of the axis on which the leaf is turned or bent. Considerable difficulty has been experienced, however, with machines of this character in the leaf wrinkling as it passes between the corrugated rolls and thereby destroying the uniformity or continuity of the corrugations as well as marring the appearance of the leaf.
The invention has for its primary object, therefore, to avoid these defects and to provide an improved machine of the class described which will produce the desired uniform corrugations.
Another object of the invention is to provide improved means whereby the same machine may be utilized for producing corrugations of either equal angles on both sides, ordshort on one side and long on the other s1 e.
With a view to the attainment of these ends and the accomplishment of certain other objects, which will hereinafter appear, the invention consists in the features of novelty in the construction, combination and arrangement of parts, which will now be described with reference to-the accompanying drawings, and more particularly pointed out in the claims.
In the said drawings, Figure 1 is a side ele vation of the upper portion of a machine embodying this invention. Fig. 2 is a front elevation thereof. Fig. 3 is a rear elevation.
Fig 4 is a plan view. Fig. 5 is an enlarged detail longitudinal sectional view of a portion of the corrugated rolls. Fig. 6 is the same, showing the sheet of paper between them, with the rolls set for producing corrugations of equal angle on opposite sides. Fig. 7 is a similar view, showing the rolls set for producing corrugations long on one side and short on the other. Fig. 8 is a detail perspective view of a portion of a corrugated sheet.
1 is a roll, provided with shafts 2, 3, mounted in suitable journal boxes 4, arranged in side members 5, of a suitable frame 6. Secured to the shaft 3 of this roll 1 is a corrugated sleeve or roll 7, and arranged immediately above this with its corrugations intermeshing with the corrugations of roll 7 is a companion roll 8, which is secured to a shaft 9, arranged parallel with the roll 1 and its shafts 2, 3, and mounted in sliding boxes 10, arranged in the side frames 5, and capable of being adjusted vertically by the aid of adjusting screws 11, so that the position of the corrugated roll 8 with respect to the roll 7 may be varied at will to suit the thickness of the paper or its peculiarities. rt hen the corrugations of the roll 8 are directly opposite to or intermesh with the corrugations of the roll 7, in the manner shown in Fig. 5, corrugations of equal angle are produced when the paper is passed between the two rolls, an example of such form being shown in Fig. 8 but should it be desired to produce a form of corrugation which is long on one side and short on the other, one of the corrugated rolls is adjusted longitudinally with respect to the other to produce the relation shown in Fig. 7, resulting in the form of corrugated sheet shown between the rolls in this figure, and which form of sheet is desirable in some instances. In order that this relative longitudinal adjustment may be brought about, one of the rolls, the roll 8 for example, may be secured to its shaft by a setscrew 12, arranged in a hub 13, to impinge the shaft 9.
The roll 1 is a feed roll, and arranged above and engaging with this feed roll are one or more additional feed rolls, which are preferably constituted by grooved rolls or pulleys 14, in the grooves of which are situated firm rubber rings 15, which press the sheet against the surface of the roll 1, and in conjunction with the latter cause the sheet to feed with a uniform movement throughout its width.
It is, of course, apparent that the corrugations in pinching the sheet have a certain feeding tendency while the feed rolls 1, 14, 15, also feed the sheet forward with a posi tive action, and unless the feeding action of these two different members or agencies be identical the sheet will feed faster on one side than on the other. As a consequence, it will buckle or wrinkle and the wrinkles will be crossed by the corrugations of the rolls, thereby throwing the corrugations out of line or breaking up their continuity as Well as damaging the sheet. In order to avoid this serious objection the corrugated rolls and feed rolls are so constructed as to have identically the same feeding power or action upon the sheet, and to this end it is necessary that the diameter of one of the feed rolls, either the upper or lower roll, be constant and unvarying, and for that reason one of these rolls, preferably the lower roll 1, is made of rigid material so that the pressure of the rubber rings 15 will not vary its diameter, and as a consequence, the feeding action of the rubber and the rigid roll will be the same at all times, however much the rubber roll may be compressed. The pitch diameter of the corrugated rolls must also be ascertained and must be the same as that of the roll 1, for the same reason. It is found in practice that this pitch diameter is not the apex of the corrugation, but is a slight distance below such ap X, and therefore the lower corrugated roll 7 at least is made a slight fraction larger than the diameter of the roll 1. This difference depends upon the extent to which the corrugations of the upper roll depress the sheet between the corrugations of the lower roll. As shown in Fig. 6, this point is neither the apex nor the bottom of the corrugation, and the pitch diameter is the mean point between the apex of the corrugation of the upper roll and the apex of the corrugation of the lower roll. By thus proportioning the pitch diameter of the corrugated roll with respect to the diameter of the feed roll the feeding action of the corrugated roll is rendered identically the same as the feeding action of the rigid feed roll and the rubber feed rolls, and hence the paper, if once started straight, will remain straight throughout its travel by always maintaining the corrugated rolls 7 and 8 in such a position that the apices of each corrugation on one roll will be spaced from the lowest point of the groove between the respective corrugations on the other roll to maintain a space therebetween, the paper will not be forced into the space between the corrugations a sufficient distance to break the calendering or surface of the paper. For facilitating the proper placementof the paper when. starting the operation, a side gage 16 maybe employed.
What I claim is:
1. In a machine for the purpose described, the combination of a pair of intermeshing corrugated rolls, and feed rolls for feeding the paper on one-side as it passes between said corrugated rolls, one of said feed rolls being the same in diameter as the pitch diameterof one of the corrugated rolls the apices of the'corrug'ations of one roll being spaced from the bottom of the groove between the respective corrugations of the other roll.
2. Ina machine for the purpose described, thecombination of a pair of corrugated rolls between which to pass the sheet, feed rolls arranged concentrically therewith for moving the sheet on one side, one of said feed rolls being the same in diameter as the pitch diameter of the corrugated roll opposed to the same, and the corrugations thereof being greater in diameter than the diameter of said feed roll the apices of the corrugations of one roll being spaced from the bottom of the groove between the respective corrugations of the other roll.
3. Ina machine for the purpose described, the combination of a pair of intermeshing corrugated rolls, disposed to maintain a space between the apices of the corrugations and the bottom of the cooperating groove and feed rolls arranged concentrically therewith and bearing one upon the other, one of said feed rolls bemg rigid and the other yieldmg.
4. In a machine for the purpose described, the combination of a pair of intermeshing corrugated rolls, a yielding feed roll arranged concentrically with one of said rolls, and an unyielding roll engaging said yielding roll and arranged concentrically with the other said corrugated roll, said unyielding roll being less in diameter than the corrugations of the corrugated roll arranged opposite it the corrugated rolls being disposed with relation to each other as to always maintain a space between the apices of the corrugations and the bottom of the cooperating groove in the other roll.
5. In a machine for the purpose described, the combination of a pair of intermeshing corrugated rolls between which to pass the sheet, said rolls being so disposed with relation to each other as to prevent the paper from being forced to the bottom of the grooves between the corrugations and means whereby one of said rolls may be adjusted longitudinally with respect to the other.
6. In a machine for the purpose described, the combination of a pair of intermeshing corrugated rolls and feeding rolls for feeding the paper onone side as it passes between said corrugated rolls, one of the feed rolls being the same in diameter as the pitch diameter of one of the corrugated rolls, said corrugated rolls being so disposed with relation to name to this specification, in the presence of each other that the side of the corrugations two subscribing witnesses, on this 2nd day will impinge the paper and the paper will be of February A. D. 1906.
