ABSTRACT:
Strip feeding mechanism intended for use in a stamping and forming machine comprises an intermittently rotated sprocket wheel which is located adjacent to the operating zone of the machine in which the stamping and tooling is located. The strip material is held against the periphery of the sprocket wheel by a retaining shoe so that the sprocket teeth will enter pilot holes in the strip and advance the strip during feeding intervals. During non-feeding intervals, the pilot pins which are part of the stamping and forming tooling, will adjust the position of the strip relative to the tooling performing the operation thereon. The construction of the biasing shoe and the sprocket wheel is such that the strip is not firmly held by the feeding mechanism and can be moved by a very slight amount by the pilot pins in order to position the strip precisely in the operating zone.
