ABSTRACT:
Apparatus and method for automatically or manually controlling the apparatus for trimming or cutting leads of electronic devices of the type having an elongated body portion, and a plurality of leads extending from the opposite side edges of the body portion, more specifically for trimming leads of dual-in-line-devices (DIP devices) of a type used in conjunction with printed circuit boards (PCBs), wherein component dimensions and materials vary, and adjustments are provided to accommodate for different width and length sizes and more particularly to permit trimming of lead lengths to appropriate length for coaction with various PCBs. The apparatus of the invention is adjustable for compensating for entry gate assembly, support track or guideway for automatically moving the DIPs into and from different stations, from entry to discharge, for lead trim lengths and shear width capable of trimming different width leads quickly, accurately and reliably and the trim mechanism is functional absent bending or bowing of the leads in the cutting action.
