Abstract: A cutter ring for use in trimming printed circuit board leads and a method of forming the ring is the subject of this invention. The cutter member is of annular configuration and is provided with a central hub portion surrounding an aperture. The cutter member itself is formed from a hardened sintered carbide which can only be shaped through a prolonged grinding operation. A molded cap is formed over the hub portion to present a surface which is to be received within a tool holder such as an arbor. The molded cap is characterized by being formed from a relatively soft workable material which can be shaped through a machining operation.

Abstract: An apparatus for trimming electrical component leads depending from a circuit board includes a plurality of cutters mounted on and spaced along a cutter mounting member supported on a frame supporting a drive motor operatively connected to the cutters for rotating same to trim electrical component leads depending from a circuit board as same is moved along a path structure supported by the frame and above the cutters. The drive motor and cutters are arranged in a pattern so that lead trimming occurs in a minimum area, length, or distance along the path 1. The cutters are adjustable vertically so that the cutters trim the leads at a predetermined spacing from a lower surface of the circuit board.

Abstract: A printed circuit board support as such board is moved through processing operations and including a defined path having guide ways receiving side portions of a carrier for a board being processed and a plurality of fibrous members such as rotatable brushes with the bristles of a stiffness engaging the board to support same at a desired level during processing such as cutting of depending leads to a final length.

Abstract: A carrier adjustable in size for holding various sized printed circuit boards during manufacturing procedures including installation of components fluxing, soldering, trimming and the like and includes a frame having conveyor engaging members mounted thereon. Laterally spaced carrier side members are adjustably supported on the frame and are adapted to support respective side edge portions of the printed circuit board. Longitudinally spaced carrier end members are adjustably supported on the frame and are adapted to support respective end edge portions of the printed circuit board. The conveyor engaging members of the frame are adapted to support the carrier on a support surface and to permit vertical stacking of like carriers.
