11 claims.
This application relates to the art of folding wax paper or the like and discloses methods and machines for continuously unrolling flat wide ribbons of waxed paper from supply rolls on which such ribbons `are wound and continuously folding and creasing the unrolled wide ribbons into folded and creased narrow ribbons of the wax paper. l
This application is a continuation in part of my prior application Serial No. 119,968 of January l1, 1937.
For an understanding of the methods and machines herein disclosed, reference should be had to the accompanying drawings illustrating the machines. In these drawings,
Fig. 1 is a perspective Aelevation view of important operating parts of a single folding machine, showing wax paper being folded by such machine;
Fig. 2 is similar to Fig. l, showing the parts in true elevation;
Figs. 3 and 4 are cross sections on lines 3 3 and 4-4 of Fig. 2;
Figs. 5 and 6 are views similar to but reversed from Figs. 1 and 2, respectively;
Figs. 7 and 8 are, respectively a perspective plan and a true plan of the machine;
Figs. 9 and 10 are cross sections on lines 9-9 and III-I0 of Fig. 8;
Fig. 11 shows a double folding machine;
Figs. 12 and 16 are sections on corresponding lines of Fig. 1l;
Fig. 13 is a view as if on the left end of Fig. 11, looking towards the right.
Figs. 14 and 15 are elevation and plan views.
For an understanding of the machine and method of Figs. 1-10 hereof, reference should be had.to these figures of the drawings. In these drawings there is shown at I0 a supply roll of flat wide ribbon of waxed paper WP resting upon a table II suitably supported on the frame I2 and adapted to be caused to rotate continuously on the vertical axis of the shaft I 4 as indicated. The supporting means for the roll Il is made vertically adjustable by suitable means vto insure the roll being suitably centered with respect to the remainder of the machine, and particularly the form to be described. Adjacent the table, which comprises a means for holding the supply roll as it is being unwound, is disposed a vertically mounted guiding roll I5 adjacent which is the head end I6 of a form I'I over which the wide ribbon of waxed paper passes on its way from the vertically mounted supply roll Ill to the horizontally mounted creasing means. The latter comprises rolls I8 disposed adjacent the tail end I9 of the form Il and having between them ahorizontalslot 20 through which passes the folded ribbon of wax paper as it leaves the form I1. The folded and creased paper passes out of the folding machine in the form of a folded and creased narrow ribbon to the machine which receives the folded ribbon from the folding machine, the receiving machine being either a rewinding machine for rewinding the folded ribbon for storage or a rewlnding machine which rewinds and cuts oi the folded ribbon into small rolls of suitable length.
The form itself comprises a convex surfaced metal shell S of progressively varying cross section (see Figs. 10, 9, 4, and 3 in order) on whose outer or convex surface is a coating F of loosewoven felt or the like. The provision of the felt coating is of extreme importance and is a very important feature of the invention. 'Ihe felt prevents slipping of the wax paper ribbon as it rides over the form away from the intended path to be followed by the ribbon and insures the fold being produced in the ribbon at the intended place. Furthermore, the felt coating prevents sticking of the wax paper to the metal shell which would otherwise occur due to static created by the passing of the wax paper over the metal shell. It is understood that other materials than felt might be employed for the same purpose. For example, the coating might be in the nature of cloth, canvas, soft rubber sheeting, loose-woven ber sheeting, or the like, the important characteristic being that the coating have a rough yielding friction surface of such a nature that the wax paper in passing over the coating will not slip with respect to the coating and at the same time will not stick to the` coating due to static.
It will also be observed that in the machine shown the supply roll II) is vertically mounted whereas the mouth of the slot between the creasing rolls is horizontally disposed. It has been found in actual practice that this relative arrangement, and the disposition of the supply roll on a vertical axis, operates satisfactorily, whereas other arrangements proposed have been found not to operate satisfactorily. It is not now known why the provision of. the supply roll on a vertical axis, coupled with the disposition of the creasing slot on a horizontal axis, operates satisfactorily, but it has been found as a fact that it does. It is therefore believed that this is an important feature of the invention.
Resiliently mounted adjacent the tail end I9 of the form and arranged to ride continuously on and against and preferably nearan edge of the wax paper as it passes over the form is a rubber-faced squeeze roll 2| which has been found useful toK help hold the wax paper against crawling as the paper passes along the form and through the creasing rolls. 'Ihe provision of the resiliently mounted soft-faced roll riding continuously on the wax paper ribbon as it passes over the form is also considered an important feature of the invention.
In the machine of Figs 11-16, which is a double folding machine, the paper 4u unrolled from the supply roll 4| passes under a thin forming plate 42 supported from above by a hanger 43 and the paper then proceeds over the rst roll 44 of a rewinder (not shown). On its way from the supply roll 4l to the former 42 the paper passes under a deflectingoll 45 which deects the paper so that `it assumes the U cross section shown in Fig. 16. As the paper leaves the deiiecting roll on its travel along the forming plate 42 it passes under weighted soft-faced rolls 46 which function to fold the paper down onto the forming plate 42 so that as the paper passes beyond the rolls 46 it has the cross section shown in Fig. 12.
As the paper passes over the roll 44 a slitting wheel 4l slits the paper longitudinally as shown in Fig. 13 so that the Wide band which left the roll 4l and was folded as it left rolls 46 becomes two independent and separate folded strips to be rewound in the rewinder.
Now having described the machine and method hereof, reference should be had to the claims which follow for a determination of the protection sought by this application.
