This invention has reference to roll and spool cutting and winding machines and it is intended to improve the construction and manipulation of machines and devices of the kind referred to, to keep the several rolls clear of each other, to obtain smooth layers with sharp edges and to produce other important objects and advantages to be referred to. In its broad aspects the invention relates to a roll-cutting and winding machine in which the cut and properly wound rolls or spools are carried by rotating supporting rollers producing the operation of the rolls to be rotatingly. wound in combination with 1 means of so disposing the supporting frame for the guide rollers and the circular knives as to make them vertically recinrocable and causing said supporting frametobearuponthe rolls to be wound by means of a pressure roller. In accordance with this invention the lower knife roller operatesas a pressure ticularly in the case of machines with movable winding mandrel and withoutsupporting rollers, but with all these machines in accordance with the previous art the width of the pieces of work was only limlted and they were not adapted for the manufacture 4% of rolls with large diameter of say, about 1 meters. In connection with heavy cutting and winding machines it was common heretofore to only use single knives for the lower knife roller likewise and to lead the paper or the like, after its having left the cutting members, first over a pressure roller which bears upon the roll of paper to be wound. Vhen working material of great widths with machines of the kind described there is WINDING MACHINE 132,644, in in Germany November 6, 1925.

the drawback that the cutting edges of the cut rollers are liable to overlap or to run one into the other, and that the several individual rolls can only be severed from each other by the exertion of very great force, thus for instance, by the driving in of wedges or the like. IVith a view of keeping the several cut webs of material separate from each other it has also been proposed to employ various constructions of cut-separators which, however, were open to the difiiculty that in the case of a somewhat inexact adjustment injury and laceration of the edges of the paper or the like were likely to occur. The modern printing machines require, however, an unobjectionably well cut roll of paper with pen fectly smooth front sides of the roll without fissures and torn portions andequivalent objectionable feature inasmuch as otherwise the running of the plant is very considerably interfered with and retarded.

Now, in accordance with the arrangement according to this invention these difiicultiesare avoided by the fact that the winding of the cut rolls takes place in a perfectly quiet and regular manner, and by dispensing with the use of special cut-separating devices. By this means it is also possible to employ winding cores or mandrels of comparatively thin diameter, thus for instance of about 50 millimeters or 2 inches, and the diameters of the rolls to be wound may be increased to about 1 meters or 5 feet. This is a point of great importance in view of the fact that by this means the rapidly rotating printing machines by avoiding'the frequently occurring interruptions of work with comparatively small rolls, are caused to operate more economically.

The invention will be more fullydescribed with reference to the accompanying drawing showing by way of example an embodiment of the principles of the invention in Figure 1 in vertical longitudinal section, and in Figure 2 in partial cross section on the line AB of Figure 1, while Figures 3 and 4 show details on: an enlarged scale to be referred to. Figure 5 is a modified form of construction in vertical longitudinal section. Figures-6 and 7 show a portion of the cutting roller respectively in longitudinal and in transverse section and on an enlarged scale.

In the frame 1 of the machine thesupporting rollers 2, 3 for the rolls 5 are mounted which latter are to be wound upon the winding core 4, the said rollers 2', 3 being actuated by a pulley 35 and gear wheels 36, 37, 38. The guide rollers 6, 7 and S for the Web of material, paper or the like 9 and the circular knives for cutting the web longitudinally a re mounted in a support 10 which, by means of link-motion 11, is pivotally mounted on the shaft 12 on the machine frame. Nith studs or trunnions 13 the lower knife-roller is j ournaledin the sliding bearings 14 which are guided for vertical movement in the prismatic'guides 15 on the machine frame. The

, lower knives are formed by dove-tailed anafork-shaped holder 20.

nular grooves in steel rings 16 which are provided with a' plurality of such grooves arranged adjacent each other. The rings 16 are'litted at proper distances apart upon the roller core 17, and are secured in position by intermediate rings 18. By a suitable distribution of the knife rings 16 they may be adjusted to suit all possible widths of rolls to be cut. Instead of an upper knife shafta series of knife or cutting discs 19 are provided which are made to run upon the ball bearings of a shaft 21 which is eccentrically disposed in The several knives are adjusted and locked in position by means of supporting arms 22 upon a bar 23 along which they are longitudinally displaceable. Upon the shaft 21 of each individual upper knife 19 a manually operated lever 24 is mounted, the spring-operated handle 25 of which is adapted to engage by means of st'ud 26 with the recesses 21, 28 of a segment 29 connected to the fork 20. Bythe rocking of the levers 24, 25 in view of its eccentric arrangement the cutting disc 19 is lifted out of the groove 34 of the lower knife roller constituting the counter-knife or made to engage therewith (Figure 4), while atthe same time by the upwardly inclined surfaces 30, 31 or the parts 24 and 29 an axial displacement of the knife 19 is produced and in such a manner that the knife 19 upon being lowered is spaced somewhat from the cutting edge of the groove 34 of the counter-knife and is only displaced towards the same after being lowered, while upon the disengaging and raising of the knife the said knife first recedes laterally away from the counter-knife and is only lifted after that. In the operating position the knife-19is resiliently pressed against the counter-knife by means of springs 32 and Figure 1 shows the supporting member '10 in the lowest position at the beginning of the operation. Upon the increase of the diameter of the roll the pressure rollers 16, 18 which bears upon the roll and which operates directly as a knife shaft. is raised, and slides in the vertical guides 15. the links 11 permitting ing web of paper.

the rocking movement of the supporting member 10. In accordance with the novel manner of winding a smooth, quiet and uniform movement of the web of paper or the like and an unobjectionable winding of the rolls in form of a dense hard sounding body is obtained, as already stated, even in the ease of very large working widths.

The modification according to Figures 57 is mrticularly distinguished by the fact that in the undercut or dovetailed annular grooves of the pressure-roller and lower cutting roller the edges opposite the cutting edges are flattened, by which means, when the web of paper is cut, a very advantageous flat bending of one of the edges of the web of paper and positioning of this edge in the annular groove of the lower knife is accomplished. This paper edge is thereby protected against being crushed, and in view of the shortening of the paper edge due to the bending which is of no consequence in the practical operation, this edge is easily retained within the annular groove of the cutting roller uponits way from the cutting point to the winding point, so tnat the web of paper or similar material is secured against lateral displacement and against becoming entangled with the adjoin- At the same time the bentorer edges are protected from strain in such a manner that they will lay down again flat, when being wound up, so that paper rolls with smooth, unobjectionable end surfaces may be obtained which is of great importance -in the further treatment of the wound-up paper, thus for instance, on modern, rapidly moving rotary printing presses for newspapers and the like. The cutting edges 40 pro-. duced by the annular grooves 39 on the rings 42 of the knife roller are arranged opposite the edges 41 which are inclined laterally in i such a manner that the lateral edge 43 of the cut web of paper 44 is bent flat downwards and into the annular groove,39 by the action of the back of the circular knife 45, and this flattened portion remains in this groove until it reaches the winding-up point. By this means lateral displacement of the web of paper 44 is prevented and an unobjectionable separation of the adj acently wound rolls of paper or the like is accomplished. The supporting post 47 carrying the circular knives and the guide rollers 45, 46 is movably guided like a carriage on vertical guides 48 of the machine frame 49, so that the rocking hinges and the "like provided for the corresponding supportmg member of the embodiment first described may be dispensed with. The invention is susceptible of other modifications andchanges to suit existing conditions and varying local and other requirements and Without deviatin g from the spirit and scope of the invention, as particularly pointed out in the appended claims.
