ABSTRACT:
Apparatus for feeding stitches of adhesive tape for binders of continuous forms for tabulating machines with a sprocket wheel for feeding each stitches so as to insert the leading end of each stitch into a corresponding hole of the perforation provided at the margins of the forms. The forms and the stitches become superimposed to each other during a binding phase and a pair of rolls engaged then for moving the forms and fixing the leading ends of every point under the lower form. A pair of rolls are provided for moving the adhesive tape in a direction perpendicular to the forms advancement, and intermittent advancement is obtained through a ratchet system associated with a "cosmodrome" cam; a head vertically rotating in the direction of the forms advancement, is provided at least with an eccentric cutting edge and a corresponding presser to operate, at every revolution. The cutting of the adhesive tape is done to obtain a binding stitch therefrom which is moved into cooperation with a facing rubber-coated roll which lifts the forms from the tail trailing end of the stitch off the upper form. A drive is provided for carrying out the rotation of the head in synchronism with the advancement of the forms to be bound, and an arrangement for carrying out the advancement of the adhesive tape in synchronism with the rotation of the head.
