6 Claims.
In high speed folders where sheets are cut from associated traveling webs it has been usual to provide impaling pins for carrying the leading ends of the webs around collecting or folding cylinders. The use of these impaling pins has been a detriment, especially in high grade magazine work because of the necessity of using extra paper so that the pinholes will come outside of the trim.
The object-of my invention is to eliminate the impaling pins and their delicate operating mechanism which are, of themselves, speed curtailing elements.
My invention comprises, generally, a pair of cutting and folding cylinders having coacting cutting and folding devices, the cutting devices serving to almost sever successive groups of sheets from the webs, and the folding devices serving to fold the alternate groups of sheetsto each cylinder and to tear the sheets of each group as it is being folded, from the sheets of their next preceding group, thereby causing the sheets of one group to carry the leading ends of the webs partly around one cylinder and the next succeeding folded group to carry the leading ends of the webs partly around the other cylinder.
A practical embodiment of my invention is represented in the accompanying drawing, in
which Fig. 1 represents in diagrammatic side elevation a folder showing one pair of coacting folding devices in the act of folding a group of sheets to one of the cutting and folding cylinders and at the same time tearing the leading ends of the sheets of that group from the tail ends of a next preceding folded group carried by the other cutting and folding cylinder;
Fig. 2 represents a similar view with the coacting folding and cutting cylinders advanced one-fourth of a revolution and showing one pair of coacting cutting devices operating to almost sever a group of sheets carried by one cylinder from the associated webs being fed into the folder;
Fig. 3 represents a face view of a knife having a serrated edge with a plurality of cut-out portions therein; and
Fig. 4 represents a detail plan view of a web showing the type of cut made by the knife to almost sever the sheets therefrom.
The traveling webs are denoted by l and the pair of coasting web associating and feeding rolls by 2, 3. The pair of coacting cutting and folding cylinders 4, 5 may be driven at a predetermined speed, by any well known or approved means not shown herein.
Each of the cylinders 4, 5 carries at equally spaced distances around its periphery, a cutting knife, folding jaws, a cutting block and a folding blade. The cutting knife 6, folding jaws 1, cutting block .8 and folding blade 9 on the cylinder 4 are arranged to coact with their respective cutting block to, folding blade II, cutting knife I 2 and folding jaws It on the cylinder 5, to almost sever successive groups of sheets from the associated webs, to fold alternate groups of sheets to each cylinder and to tear the group of sheets as it is being folded on one cylinder away from the next preceding folded group on the other 1 cylinder. The cutting knife is shown as having a serrated cutting edge [4 with a plurality of cutout portions l 5 along the same to leave short uncut portions [5 between the sheets and webs as the sheets are almost severed from the webs.
The deliveries which I have shown for the cutting and folding cylinders may be constructed, arranged and operated as follows:
Rotary delivery cylinders l1, l8 coact with and travel at a lesser speed than their respective cut.- ting and folding cylinders 4, 5. In the present instance these delivery cylinders are caused to travel at two-thirds the surface speed of the cutting and folding cylinders by any Well known or approved means not shown herein. h
Three equally spaced sets of grippers I9, 20, 2| are carried by the delivery cylinder ll, and three equally spaced sets of grippers 22, 23, 24 are carried by the delivery cylinder l8.
In operation: Presupposing a plurality of associated webs are to be fed to the cutting and folding cylinders. As these webs are fed through the cutting and folding cylinders the coacting cutting devices on the cylinders almost sever successive groups of sheets from the webs. The folding devices on the cutting and folding cylinders serve to fold alternate groups of sheets to each cylinder where the folded groups of sheets are delivered to their respective delivery.
It will be understood that as one group of sheets is folded onto one of the cutting and folding cylinders the leading ends of the sheets being folded are torn from the tail ends of the sheets which comprise the next preceding folded group of sheets on the other cutting and folding cylinder. This obviates the necessity of impaling pins on the two-cutting and folding cylinders for temporarily holding the leading ends of the webs or sheets thereon.
It will also be understood that the cutting and folding devices may be of any well known or approved form and may be operated in the well known manner by suitable means not shown herein.
It will also be understood that by the term rotary cylinder as used herein, I intend to include rotary carriers of any form capable of advancing the webs and sheets in the desired paths.
It is evident that various changes may be resorted to in the construction, form and arrangement of the several parts without departing from the spirit and scope of my invention, and hence I do not intend to be limited to the particular embodiment herein shown and described.
What I claim is:
1. In a folder, a pair of cutting and folding cylinders, means for feeding a web or associated webs thereto, cutting devices on said cylinders operating to almost sever successive sheets or groups of sheets from the web or webs, and folding devices on said cylinders operating to fold alternate sheets or groups of sheets to each cylinder and to tear each sheet or group of sheets as it is being folded, from the next preceding folded sheet or group of sheets, thereby causing the folded sheet or group of sheets to carry the leading end or ends of the web or webs partly around one cylinder and the next succeeding folded sheet or group of sheets to carry the leading end or ends of the web or webs partly around the other cylinder.
