ABSTRACT:
A reinforcing piece pasting an apparatus for pasting annular reinforcing piece around a binding which is punched before-hand on a document. The purpose of the invention is to provide a reinforcing piece pasting apparatus which, by a simple operation, enables one to feed a reinforcing piece to a prescribed position securely and one piece at a time, and to paste the reinforcing piece correctly around the binding hole.
The reinforcing piece pasting apparatus in accordance with the present invention has a base, a frame, and a handle whose base end parts are combined pivotally so as to be turnable relative with each other and which are urged by springs in the direction to have their tip parts separated further away. By inserting a document with a punched binding hole into the opening between the base and the handle to fit the binding hole to a projection on a pasting table formed on the base, and by closing the base and the handle in this state by applying a pressure on them from both sides, the reinforcing piece is fed on a supporting part piece by piece by a feeding mechanism, and the reinforcing piece fed is pressed against the document that is placed on the pasting table to be bonded to the periphery of the binding hole by means of a presser formed on the handle.
