ABSTRACT:
Picture hangers having prongs become automatically inserted into a picture backing material. An insertion apparatus feeds a strip of preformed blanks to an anvil which severs the blanks and presses them into the backing material. At the same time that the apparatus severs the first blank of the strip, a prong forming tool, attached to the anvil, bends the prongs of the next blank. A feed rod advances the strip of blanks through the apparatus, one blank at a time. A pair of paws, attached to the anvil, carry the severed hanger to the picture backing, and releases the hanger as the hanger becomes inserted into the backing. The apparatus includes a resilient structure which enables the device to operate efficiently with picture backings having varying thicknesses. One can also use the invention to insert hangers into picture frames, mirrors, plaques, signs, or the like.
