Abstract: Dimpling and riveting a workpiece wherein the workpiece is clamped, the dimpling, drilling and riveting occur sequentially while the workpiece is clamped, and the workpiece is heated prior to dimpling. During clamping a pressure foot force is applied to one side of the workpiece, and during dimpling a force is applied to the opposite side causing slight movement of the workpiece against the pressure foot force. The dimpled recess in the workpiece is about the shape of a truncated cone and a rivet-receiving hole is drilled through the workpiece in the recess. To provide a fluid-tight seal, the minor diameter of the truncated cone is made slightly greater than the diameter of the rivet-receiving hole thereby providing an annular step between the hole and the outwardly diverging wall of the dimpled recess. During upsetting of the rivet the workpiece material is compressed radially around the annular step to provide a fluid-tight seal between rivet and workpiece.

Abstract: A layer of padding is centered on a sheet of upholstery material. A rail is centered top down on the layer, and this feed assembly is moved continuously along a feed path by driven rotating rollers contacting the rail. The rail is forced by the roller toward a smooth slide face, which presses the sheet and layer against the rail top. The sheet slides along the smooth slide face. Smooth faced fences have inclined edges that progressively fold, pull taut, and then press the sheet toward the rail, compressing the layer. Guides with smooth faces and inclined edges fold the remaining sheet against the rail. The edges of the sheet are stapled or glued to the rail, producing a cap or padded rail with a taut, uniform upholstery covering. The staples or glue is inserted when the feed assembly has moved a desired distance along the feed path.

Abstract: A conventional fastener attacher is fixedly mounted on a support. A stack of hooks is situated in a retainer which is movably mounted with respect to the support. A dispensing slide is movably mounted on the retainer, below the stack. As the retainer is moved towards the attacher, the slide automatically moves relative to the retainer to align a hook with the attacher. Slide movement is achieved through the use of a cam surface on the support and a cam follower extending from the slide. A single air cylinder moves both the retainer and the slide. The retainer can hold the stack in one of two orientations. In order to avoid jamming, the hook is held on the slide as it retracts or is realigned with the stack, if the hook has not been removed from the apparatus.

Abstract: Various permutations of plugs (13) are inserted in keying holes (12) formed in a connector 10 secured to an edge of a printed circuit board (11).

At the inspect station, checks are made for missing plugs and plugs in wrong holes. If plugs in wrong holes are detected, the plugs are dumped from the carrier nest and a new array of plugs are loaded into the carrier nest (16). If a missing plug is detected, the carrier nest is returned to the load station and a plug is loaded into the proper nest hole (17).

Abstract: An improved offset collator comprising a sheet gripper/injector transport station and an oscillating sheet receiving station. Copy sheets are transported to the sheet gripper/injector transport station in a specified sequence whereupon they are gripped by the transport station, and in a reciprocating motion, transported to the oscillating sheet receiving station where they are injected into a stack of sheets and released. The oscillating sheet receiving station is synchronized with transport station such that the copy sheets are inserted in the oscillating sheet receiving station in an alternate offset posture. A cooperating logic control system causes the sheets to be inserted into the oscillating sheet receiving station in the proper order and offset. After offset collation is completed, the offset stapling station then cooperates with the oscillating sheet receiving station to staple sets of sheets still in their offset posture.
