Abstract: A stop mechanism operative to stop a sprial lacing wire if the lacing wire encounters an obstacle as it is being wound in lacing fashion about juxtaposed end loops of coil springs in two adjacent coil spring rows, and after the lacing wire has completely laced together those two spring rows. A sensor functions to sense when the spiral lacing wire encounters an obstacle in its lacing path, the sensor incorporating a proximity switch that cooperates with a bowed guide element. The bowed guide element induces the lacing wire to pop out or bow away from the switch when the obstacle is encountered, activation of the switch causing the lacing wire to stop at once in its lacing path. A clamp device cooperates with a feeder switch to clamp the unlaced spiral lacing wire between its jaws when the feeder switch is activated by the lacing wire's lead end after the lacing wire has traversed the entire length of the adjacent rows.

Abstract: A mechanism for bending a coplanar family of straight wires into zig-zags comprises deflector rollers for feeding the family of wires longitudinally in parallel with one another, bars adapted to be displaced transversely to the wires and carrying wire deflector pins, and a control device for moving the bars alternately in opposite directions transversely of the wires. In order to avoid sliding of the wires against the deflector pins during the bending operation, each bar is hinged to the one ends of at least two parallel bearer arms of equal length and pivotally supported about axes running perpendicular to the plane of bend. During each bending operation only one bar at a time can be displaced transversely by means of the control device to carry out a working stroke.

Abstract: A wire unwrapping tool comprising a cylindrical shaft having an outer axial bore at one end, and an inner bore further within said shaft, concentric with and opening to said outer bore. A third bore is located through a diameter of the tubular shaft in such a position as to define sharp gripping edges at the inner face of said outer bore, for grasping the conductor wire to be unwrapped when the shaft is placed over the wrapped terminal. In a further embodiment, the shaft includes axial gripping edges extending from the end of the shaft to the diametrical bore.

Abstract: A wiring loom includes a multiplicity of shouldered pins and a table for receiving and releasably holding the pins in position to define paths for a wiring harness. The table includes a mesh which allows ends of the pins to pass and enter a resilient penetrable layer below the mesh. The mesh cooperates with the pins to prevent complete passage of the pins through it. Wires are held by injecting the leading end of a wire into the mesh, looping the wire around a start pin and then laying the wire along paths defined between pairs of pins. The wire may finely be looped around a terminating pin. Collars may be disposed over the pins to provide a platform for the wire. In a preferred form there is a further light nylon mesh above the first mesh. The pins can pass through this light mesh. When a wiring harness is completed, the light mesh is raised to free the harness from the pins and the table is inverted so that the harness falls onto a conveyor.

Abstract: A wire harness manufactured by a new method and a new apparatus is provided. A covered wire paid out from a selected one of reels is extended in a predetermined lay-out and fixed. The thus fixed wire is cut-off from the reel. Then, another wire is paid out from another reel for arranging it in a juxtaposing relation to the previously laid-out wire and cut off from the reel. After repeating the above steps, the arranged wires are tied up to form a wire harness. There is also provided a device which puts the above method into practice, thereby reducing complicated assorting work involved in the manufacture of a wire harness. A method and a device for automatically uncovering end portions of each wire of the wire harness and attaching terminals thereto are also provided to greatly increasing the productivity.

Abstract: A barrier-type metal wire fabric which is substantially free of transverse passages while providing desired travel path flexibility is disclosed along with methods and means for its manufacture. Shaped wire with at least two diametrically opposed planar surfaces is helically wound with a planar surface confronting the working surface of the winding mandrel. Left-hand wound and right-hand wound spirals are assembled with individual loop portions of each being nested within the loops of its next adjacent oppositely-wound spiral. A connector rod inserted within longitudinally overlapping internal loop portions of such spirals provides for pivotal relative movement between adjacent spirals and desired travel path flexibility while the dimensional relationships and assembly taught substantially eliminate non-rotational relative movement between metal wire elements of the fabric.

The apparatus (50) is comprised of a pair of wire cutters (52) with a pair of opposed rollers (74, 76) associated therewith. The rollers (74, 76) are mounted for relative movement away from one another to enable an insulated wire to be passed therebetween and into the wire cutters (52). The rollers (74, 76) are also relatively movable toward each other for engaging and softening the wire (21) insulation upon actuation of the wire cutters (52) to cut the wire.

Abstract: Filament reinforced cylindrical plastic screens having open slots defined by their surface wires which are of substantially different widths can be produced on a single helically finned mandrel. The slot widths are varied in accordance with the amount of wire-forming material placed in the generally V-shaped grooves defined by the mandrel fins. The grooves have a double relief angle so that the lower support portions of the surface wires will be formed so as to have a slightly tapered, radially elongated cross-section and the upper portions of the wires will have their sides at a substantially greater relief angle. This relationship permits a relatively small change in the total height of the wires to have a substantial effect on the width of the top portion of the wires, and thus, on the width of the slot openings which can be formed between adjacent wires.

Abstract: Rows of springs are periodically supplied to a mattress spring core assembly machine 7 by a transfer system 6. The springs are taken, in turn, from one of two conveyor belt pairs 4, 5 by the transfer system. The individual springs are produced by spring coiling machines 1, 2 with each machine feeding one conveyor belt pair. By periodically shifting the transfer system 6 its gripping arms 20 can alternately take a row of springs from one or the other conveyor belt pair, thus doubling the overall production rate.

Abstract: A hand tool is disclosed for straightening wire and includes three elongated rod-like wire straightening members each having a plurality of wire engaging circular ridges spaced longitudinally of the respective straightener member. Link means interconnects the wire straightener members at the ends thereof for pivotal movement relative to the longitudinal axes thereof, between an open position and a closed position. The wire straightener members in the closed position define a longitudinal passageway between the circular wire engaging ridges for receiving a wire and straightening the wire in response to relative longitudinal movement of the wire in the passageway as pressure is applied exteriorly of the wire straightener members. The circular ridges on each wire straightener member are spaced and located to be disposed in gaps between the circular ridges of each other wire straightener member.
