ABSTRACT:
A dual paper binding and multiple punch apparatus (10) includes a punch lever (17) operating bending blades (58) for bending flexible studs (63) of one binding strip (60) into grooves (62) on a second apertured binding strip (61) through which the studs pass after being passed through holes of a stack of apertured paper sheets. Racks (64, 69a, 69b and 69c) and gears (66a, 66b and 70) link the punch lever (17) to a pair of shuttles (68, 72) mounting the bending blades (58). The strips (60, 61) and paper stack (6) are first compressed by a rotory pressure bar (42) containing tangential fingers (36) cam operated by a slide bar (51) by manual movement. A cover (16) encloses the compression and stud bending mechanisms when not in use and is extendible to form an additional platen (23a) to support the paper stack (6) being bound.
