24838-51 ABSTRACT Apparatus for feeding stitches of adhesive tape for binders of continuous forms for tabulating machines has a sprocket wheel to insert the leading end of each stitch into a corresponding hole of the perforation provided at the margins of the forms super- imposed to each other in the binding step. A pair of rolls move the forms and fix the leading end of every point under the lower form. A pair of rolls move the adhesive tape in a direction per- pendicular to the form advancement. Intermittent advancement is obtained through a ratchet system associated with a "cosmodrome" cam. A head rotates vertically in a plane parallel to the direction of form advance and is provided with at least one eccentric cutting edge and a corresponding presser to effect in each revolution cutting of the adhesive tape to obtain a binding stitch therefrom, and then fix (in cooperation with a facing rubber-coated roll which lifts the forms) the tail (or trailing end) of the stitch on the upper form. Rotation of the head is carried out in synchronism with the advance of the forms to be bound in advance of the adhesive tape is done in synchronism with the rotation of the head.
