ABSTRACT:
A method and apparatus for making plug-in fuse assemblies utilizing a strip of fuse metal having longitudinally spaced blank portions from which individual plug-in fuse elements are to be formed, each blank portion having corresponding portions spaced transversely of the length of the strip from which said fuse link portions, on the one hand, and at least said terminal blade portions, on the other hand, of a plug-in fuse element is to be formed. The strip of fuse metal is advanced past punch and die assemblies which form in each blank portion of the strip a pair of parallel confronting terminal blade portions and current-carrying extensions interconnected by a fuse link portion. A punch unit and a backing means therefor having a width no greater than about the length of each pair of terminal blade portions are positioned on opposite sides of the terminal blade portions of the end blank portion of the strip and the punch is moved against the terminal blade portions of the end blank portion of the strip to sever the same from the strip and to bring the severed blank against the backing means where it is clamped securely between the punch and the backing means. An insulating unit, preferably constituting a housing, with an entry opening at one end adapted to receive the current-carrying extensions and fuse link portion of the severed end blank is held by a housing applying unit which moves the housing over the current-carrying extensions of the end blank clamped between the punch and said backing means.
