Abstract: An automatic spiral binding apparatus for edge binding a book of sheets with a spiral coil includes a book supporting table that is indexable between loading, coil insertion, coil crimping and book discharge stations. The apparatus can accommodate a wide range of book thicknesses, coil diameters and coil pitches. Positioning hooks in the loading station are selected to correspond to the coil diameter and are mounted at an incline to match the coil pitch in a manner which pre-orients the book edge to both the proper curvature and proper pitch to facilitate subsequent threading of the spiral coil into the holes in the edge of the book at the following insertion station.

Abstract: An automatic cutting and crimping apparatus for a spiral coil binding a book of sheets includes a pair of trim heads slidably attached to a slide bar mounted on a trim station that is part of a larger spiral binding apparatus. The trim heads include a pair of stationary crimping jaws which engage and hold the lead and trailing ends of the spiral coil while a rotating cutting jaw cuts the ends of the coil as they are held against a stationary cutting jaw. The rotating cutting jaw continues to rotate so that the ends of the coil are crimped inwardly and upwardly toward the book of sheets to provide offset ends which serve to inhibit unintentional withdrawal of the coil from the holes along the edge of the book. After the coil has been cut and crimped, the spiral bound book is indexed to a discharge station for discharge from the spiral binding machine.

Abstract: An improved wire feeding and measuring apparatus having a pair of cooperating feed belts to feed a wire in an axial direction. A drive wheel is located downstream of the feed belts and rotates in contact with the wire at a slightly faster speed than the feed belts, while a measuring wheel, operably connected to an encoder, is also engaged with the wire and is located opposite the drive wheel. The measuring wheel is biased toward the drive wheel by a spring exerting a light force. Guides are associated with each wheel and each guide includes a wire supporting surface and a slot located adjacent the supporting surface. The periphery of each wheel projects a slight distance through the slot in the respective guide and engages the wire. The guides maintain the wire in a tangential relation to the periphery of the wheels and prevent wrap around of the wire on the wheels.

Abstract: A machine cuts elongated wire segments from a continuous wire strand. A belt type conveyor conveys each segment in incremental steps along a path, with the axis of each segment transverse thereto. The conveyor initially grips a segment near one end and presents it to a first terminal attachment machine on one side of the conveyor where a first terminal is attached. Then, separator devices cause the conveyor to temporarily release its grip on the wire segment to allow wire shifter devices, first, to axially shift the wire segment very rapidly a great distance so that the conveyor can regrip the wire segment near its other end and, secondly, to axially shift the wire segment slowly for a short distance to precisely position its opposite end in final position wherein a second terminal attachment machine on the other side of the conveyor attaches a second terminal to the opposite end. A control system comprises sensors for determining when the wire segment has been moved by the wire shifters.

Abstract: A belt type conveyor is provided for conveying segments of wire cut from a continuous strand by a cutting machine to other wire processing machines, such as terminal attachment machines or the like. The conveyor comprises a pair of endless flexible belts supported one above the other by pulleys and guide rails so that the upper flight in the lower belt closely confronts the lower flight in the upper belt whereby wire segments entrapped between the flights are movable along the path of travel of the confronting flights. Each wire segment is disposed so that its axis is perpendicular to the path of travel of the flights and the ends of the segment extend beyond the sides of the flights so as to be accessible to the processing machines. A drive mechanism drives the confronting flights in steps or increments in the same direction and at the same speed. The belts and guide rails are constructed so that the confronting flights are biased toward each other to ensure a firm grip on the wire segments.

Abstract: A rotary wire stripping machine for removing insulation from the end of an insulated wire including a reciprocating carriage which supports a rotating stripping head. The rotating stripping head includes a central bore for receiving the end of a wire and a pair of cutting blades which are movable radially inwardly to cut the insulation of the end of the wire. The reciprocating carriage may be moved from a first position wherein the stripping head receives the end of the wire to a second position wherein the blades pull insulation off the end of the wire.
