A spring .33 bears against the upper side of the block 30 and at its upper end bears against the frame of the machine. Another spring 34: bears at its upper end against the block 30 and at its lower end against the frame of the-machine, so that the block is interposed between. two springs 33 and-'34.

The bell-crank lever 28 is provided with a vertical arm 35,which is connected at its upper end by a link 36 to an eccentric pin 37 fastto a disc 38 which, in turn, is fast to. and is rotated by the shaft 11, which rotates in the direction of the arrow a, Fig. 1.

.Themechanism just described and herein after more fully described as to its operation, constitutes the mechanism for feeding the upper with the tape attached thereto, and also forpressing thetape, which is an adhesive tape, against the upper, so that it will adhere theret v r A reinforcing tape, Fig. 4, is fed to the upper feedinstrumentalities through a tape guide 40 which is fastened to an arm 41 which is rigidly fastened to and forms in effect a portion of an arm 42, the arm 42 being provided with a hub 43 pivoted to rock upon a stud 44 which is fast to the frame of the machine.

The tape is severed' h a pairofeutters an upper cutter '45 and a ower The upper cutter 45 is fastened to" a rockerarm 47 which is pivoted at 48 to the frame of the machine. The lower cutter 46 is *fastened to a downwardly projecting arm-.49 on .a rocker frame 50 which is pivoted a'thl to the frame of the machine :on oppositesides of the head 52 of said frame.

I claim 1. A tape attaching and severing machine having, in combination, mechanism for attaching a strip of adhesive tape to a piece of sheet material, mechanism to intermittently feed said sheet material with a tape attached thereto, a tape guide, a rocker arm, a cutter fast thereto and positioned above the tape, a rocker frame, a second cutter fast to said rocker frame and positioned beneath the tape and connected to said rocker arm, said rocker arm and rocker frame being relatively so pivotally mounted that downward movement of the upper cutter will cause the lower cutter to be moved beneath the tape and the tape to be severed by said cutters.

2. A tape attaching and severing machine having, in combination, mechanism for attaching a strip of adhesive tape to a piece of sheet material, mechanism to intermittently feed said sheet material with a tape attached thereto, a tape guide, a rocker arm, a cutter fast thereto and positioned above the tape, a rocker frame, a second cutter fast to said rocker frame and positioned beneath the tape and connected to said rocker arm, said rocker arm and rocker frame being relatively so pivotally mounted that downward movement of the upper cutter will cause the lower cutter to be moved beneath the tape and the tape to be severed by said cutters, said tape guide being mounted on a second rocker arm pivotally mounted to swing in a plane transversely of the cutting edges of said cutters, and means on said first-named rocker arm adapted to engage the second rocker arm and cause it to be moved toward and away from said upper feeding mechanism whereby the tape may be severed, the severed, end caused to assume an advance position relatively to the tape guide and the severed end fed by the tape guide to the sheet material feeding mechanism.

In testimony whereof I have hereunto set my hand.
