ABSTRACT:
Disclosed herein is a sheet perforating apparatus comprising a sheet transfer mechanism; a perforating section for boring at least one filing hole in a sheet being transferred; and a sticking section for sticking a reinforcing pad on the sheet about the periphery of the filing hole. The perforating section comprises a punch cutter for boring the filing hole in the sheet transferred. The sticking section comprises a delivery part for delivering a reinforcing pad-carrying sheet comprising a releasable base sheet and reinforcing pads which have an adhesive layer and have been stuck on the releasable base sheet at predetermined intervals; a peeling part for acutely bending and reversely turning the reinforcing pad-carrying sheet from the delivery part to peel one of the reinforcing pads gradually from its front end; a catcher having a holding part, which holds the reinforcing pad separated by the peeling part with a holding blade making use of the adhesive layer provided on the reinforcing pad in such a manner that the adhesive layer faces outwardly, and adapted to move the holding part to a sticking region; and a backing pad to be moved following the movement of the holding part of the catcher and having a flexible backing face leading to contact with the holding part with the sheet nipped therebetween.
