Abstract: There is configured a coil unit arrangement device that forms an array coil group by arranging in a predetermined arrangement order each relevant coil of a coil unit in which a plurality of coils corresponding to a plurality of phases is connected by a jumper wire for each phase, the coil unit arrangement device including: a holding section provided with a rotatable coil unit support that supports the coil unit; and a receiving section provided with an array coil group support that supports the array coil group, the receiving section relatively turning with respect to the holding section.
Abstract: A wire winding method which can prevent twisting tendency of a wire and the occurrence of damage on the wire. The wire winding method includes: a first step of making a plurality of wires pass through a tensioner and a nozzle sequentially and fixing distal ends of the plurality of wires to a core side; and a second step of winding the plurality of wires on the core while twisting the plurality of wires by making the nozzle revolve around the core such that a mutual positional relationship between a plurality of wire insertion holes formed in the nozzle through which the plurality of wires are made to pass respectively with respect to the tensioner is set to a fixed value.
Abstract: A method for manufacturing a cylindrical winding for slotless electrical machine according to the following steps: a) a winding head (211) able to move according to three axes X, Y, Z, winds continuously a wire following a predetermined winding program around two sets of needles (80) on the external surface of a first cylindrical tube (6). The needles are located on the conical shaped end surfaces of two identical cylindrical bodies axially juxtaposed and axially and rotatable movable (R). The cylindrical bodies are partially located inside the first cylindrical tube (6), b) after the achievement of the winding operation of all the electrical machine phases all around the 360° peripheral surface of the first cylindrical tube (6) a second cylindrical tube is put around the achieved winding (41); c) the two sets of needles (80) are taken away and the two cylindrical bodies are axially moved away.

Abstract: A method and device for wire termination on stators (1) wherein the wire (15) is wound about poles (6) distributed by a flyer (10), guided by shrouds (16) that move radially with respect to the stator (1) overlapping the respective pole (6). Wire termination operations are provided on the wire ends (15) into the terminals (4) with the aid of the flyer (10), carried out by an apparatus equipped with a termination device (20), comprising a first deflector (21), a second deflector (22), a blade (23), and a clamp formed by a movable gripper (24) and a fixed gripper (25). The movable gripper is suitable for closing onto the fixed gripper for gripping the wire (15). The device (20) can carry out the steps of catching, moving, introducing and cutting the wire (15) with movements parallel to its own axis (27), or to the axis (7) of the stator (1).
Abstract: A wire winding apparatus can reduce the burden of momentum on the side of the nozzle cooperated with the spindle shaft in winding operation, thereby enabling an effective winding operation. The winding apparatus comprises a carrier carrying at least one bobbin to be wound with wire, a nozzle for supplying the wire to be wound around the bobbin, a spindle shaft for rotating the bobbin, a working table disposed opposite to the nozzle and spindle shaft so as to introduce the carrier into between the nozzle and spindle shaft, wherein the spindle shaft is retractable relative to the bobbin carried on the carrier fed onto the working table so as to allow the bobbin to move between the carrier and nozzle.
Abstract: A winding device (1) for a multi polar armature, which simultaneously winds a plurality of wire rods (5) onto a core (7) on which a plurality of winding cores (9) are arranged circularly, includes an index mechanism (11) for rotating the core (7) about a central axis thereof, a nozzle (3) for reeling out the plurality of wire rods (5), and a nozzle moving mechanism (12) for moving the nozzle (3). Every time the nozzle (3) completes a single revolution around the winding core (9), a twist (6) occurring in the wire rods (5) is undone by having the index mechanism (11) cause the core (7) to perform a single revolution about a central axis (T) thereof and having the nozzle moving mechanism (12) cause the nozzle (3) to follow the winding core (9) as the core (7) performs the single revolution.
Abstract: A web-handling apparatus includes at least one guide roller assembly having an inner, cylindrical core, and an outer layer affixed thereto. Notably, the outer layer of the roller assembly comprises resiliently deformable material, with polyurethane foam having proven to be particularly suitable for this application. By this arrangement irregularities in an associated film web, such as in the form of side gussets and/or zipper fastener assemblies, are readily guided by the roller assembly while avoiding wrinkling or other stress of the associated film web.
Abstract: A coil-winding method comprises: winding first coil clockwise around first, counterclockwise around second, and clockwise around third swath along mandrel, hooks grouped into swaths; winding second coil clockwise around between first arid second hooks of first to between first and second hooks of second swath, counterclockwise around from between first and second hooks of second to between first and second hooks of third swath, clockwise around between first and second hooks of third to between first and second hooks of first swath; winding third coil clockwise around between second and third hooks of first to between second and third hooks of second swath, counterclockwise around from between second and third hooks of second to between second and third hooks of third swath, clockwise around between second and third hooks of third to between second and third hooks of first swath; and releasing wound coils.
Abstract: The reciprocating and oscillating winding spindle of a stator winding machine is rotatable through 180° to enable a stator winding and lead terminating method and apparatus for automatically winding a 2-pole stator having two pole pieces each with a coil wire wound from the same, single strand of wire. A cross-over wire segment between the two stator coils extends through the bore of the stator and is trapped against an inside wall of the stator by a cross-over wire retaining member. A stator coil lead terminating apparatus is capable of complex manipulations of stator coil lead wires at a winding station. Stator coil lead wires can be looped about wire guide posts on a stator core in the course of forming coil lead terminations, and the posts can be protected against bending or breaking by looping pins that partly receive the posts.
