ABSTRACT:
This invention includes apparatus for manufacturing a plastic name tag holder. The preferred name tag holder is rectangular and has a central cavity open at one end for insertion of the name tag. The holder has a rigid plastic bottom sheet and a rigid plastic parallel top sheet which is turned down around three sides of its periphery and is sealed to the bottom sheet on three sides to provide the central name tag slot. The slot is substantially rectangular in vertical cross-section.
The apparatus for manufacturing a plurality of name tag holders includes hinged horizontal insert fingers mounted on the lower platen to separate the top and bottom vinyl sheets and to provide a plurality of male molds corresponding to the central cavities. A plurality of U-shaped electrode dies draws the top sheet down and around the U-shaped insert fingers and seals the top sheet to the bottom sheet beyond the perimeter of the insert fingers. The electrode dies also cut the top and bottom sheets between the insert fingers so that after the sealing and cutting are completed, the operator can strip away the waste with one motion and can then remove the completed name tag holders from the insert fingers.
