ABSTRACT:
A method of and apparatus for attaching a connecting piece to objects to connect these objects to each other. The connecting pieces each having a filament portion, a head portion attached to one end of the filament portion and a cross-bar portion attached to the other end, are successively severed one by one by the attaching device from a continuous belt of connecting pieces formed integrally from a plastic and having a connecting rod to which the connecting pieces arranged in side-by-side relation are connected through respective connecting portions, and are then attached to the objects to connect them to each other. The improvement resides in a technic which ensures to correctly position the connecting piece to be severed to the severing position even when the connecting pieces in the connecting piece belt are disposed at an irregular pitch. This can be achieved by continuously pressing the connecting piece to be severed in the direction of feed of the belt until the connecting piece to be severed is stopped and located by a stopper member disposed in the severing position.
