For instance, the first two disks on the surface of the spacingwashers, while the upper shaft overlap two opposite faces of those on the lower plate curve in the opposite direction and enter the clearance-spaces between the lower disks. These fingers serve as strippers and restore the strips to the plane of movement across the table after having been deflected into the clearance-spaces by the cutting-disks.

Between suitable brackets u u, attached to the main frame, is mounted ashaft or spindle 0, having a pulley 0, through which it is rotated by means of a belt 0 driven from one of the shafts B B, as shown in Fig. 2, the speed of the spindle being somewhat faster than that of the rolls to maintain tension on the strips. This shaft carries or serves as a core upon which to wind all of the strips 2 simultaneously. In order to effect this winding symmetrically under proper tension and entirely independent of each other, we provide another roller, 1), which has its bearings in inclined slots formed in the brackets u and radiating from the axis of spindle 0 and in which it is free to rise and fall as the rolls build up or the tension changes. This roll rests on top of the series of strips 2' and is provided with a number of annular spacingiianges 7), which enter between the strips to offset them from each other slightly just before they are wound on the spindle 0. The

weight of roller 1) constantly applied to the strips and the roll always hugging the peripheries of the paper-rolls insures a symmetrical winding of the latter and that each roll shall be formed independently of the others. The roller 3) is preferably weighted and the weight 19 applied at the middle point of a bale 1), whose extremities are fixed to the respective ends of the shaft of the roll. This distribution of the weight helps to maintain the roll horizontally,while permitting it to rise in the inclined slots as the coil is built up.

It will be obvious that by adjusting the number and size of the washers between the cutting-disks the width of the cut strips may be altered as desired.

Having described our invention, we claim In a machine for slitting paper or like material, the combination or two sets or gangs of disks mounted upon parallel axes and overlapping each other in pairs to form shearing edges, the disks of one set being so spaced that each successive two of them will enter between and overlap the opposing faces of the corresponding two disks in the other set, thus providing clearing-spaces of a width corresponding to the cut strips and two sets of stripping-lingers enteringsaid clearing-spaces and adapted to direct the cut strip into one plane.

In witness whereof we subscribe our signatures in presence of two witnesses.
