Abstract: A detailing tool for processing electronic component substrate includes a supporting frame, a substrate carrier movable on the supporting frame to receive and secure the substrate during processing by the tool, and a pair of cutter assembly attached to said supporting frame for removing tails on said substrate. The cutter assemblies self-align “to” the substrate during initial substrate loading in a processing area of the tool. Each cutter assembly includes a pair of spaced, translatable and opposed cutters that simultaneously move towards each another while removing the tails from the corners of the substrate that remains stationary. The pair of cutter assemblies are symmetrically attached to the supporting frame with respect to an axis for indexing the substrate. Thus, the invention provides a tool for cutting tails from opposite corners on the substrate edge automatically and simultaneously during processing.

Abstract: A transfer line apparatus for performing multiple machining operations on each of a plurality of workpieces in a transfer line. The apparatus includes a plurality of different kinds of machining units disposed at respective machining stations along a transfer path. A workpiece transporter moves workpieces along the transfer path to position each of the workpieces at each of the machining stations and allow each of the machining units to machine each of the workpieces as the workpieces move along the transfer path. A controller connected to the machining units responds to an inspection command by causing all machining units downstream from a designated machining unit along the transfer path to allow a workpiece selected for inspection to pass by without being machined by the downstream units. This allows the workpiece to be inspected in a form that the remaining machining units have not altered.

In the area of the folding site on the side of the plane in which a separator strip section is prepared at the folding site which is opposite the side from which the plate to be jacketed is supplied, there is a pair of folding rollers.

Abstract: A powered rotary drive unit for dressing electrodes that has two handles. The operator places the cutters between the electrodes and applies clamping pressure. The operator then activates the motor to dress the electrodes. The cutter is designed to cut the electrodes to the proper shape so that the tips cannot be over-dressed.
