Abstract: A transfer and introduction tooling for transporting coils from a winding machine and for drawing the coils into a variety of stators of electric motors includes a set of carrier arrangements of differing diameters and a number of interchangeable parts forming a transfer tool, an introduction tool and a cover-strip magazine. Each carrier arrangement has a central opening and a plurality of identical receiving locations disposed about its periphery. The transfer tool is formed by combining a carrier arrangement with a plurality of transfer forks where each transfer fork has two spaced fork prongs and an extension which can be releasably fastened to the receiving locations of the carrier arrangements to form a transfer tool.

Abstract: A special winding template for coils drawable into the stator of an electrical machine haa two template havles which can be slipped onto rotating carrier bars with an adjustable spacing. One of the template halves has, on the base side, a detachable coil support with a receiving orifice for a third carrier bar. To avoid always having to make a new winding templates for different types of windings and stator dimensions a modulator system is provided, so that templates of any constructional shape and size can be produced from a manageable number of different elements. Accordingly, a template half consists of a central piece (5) which can be slipped onto the respective carrier bar and of individual part templates (10) which each have a wire chamber and which can be slipped onto the central piece (5), the radial jump between individual part templates being selectable by means of spacer pieces (17) insertable between them.

Abstract: A device and a process for the functionally combined production, transfer and installation of coils (11a, 11b, 11c) into the stator (12) of electrical machines using installation strips (18a to 20b) provided with spreadable tongues. A ready-wound coil set (11a, 11b, 11c) is taken off the winding machine with its formers (4, 4a), moved to the stator (12), maintaining the spatial stepping and the flat shape of the coil phase windings, transferred directly from the formers (4, 4a) into the installation strips (18a to 20b) inserted into the stator (12), and drawn into the stator (12) as a whole in a single operation. One of the two formers (4) is provided with a preferably detachable support element (13) which lifts the coil heads out of the former chambers by turning the former about the axis of its carrying rod (3). For easier introduction of the coil phase windings into the installation strips ( 18a to 20b), their strip tongues are arranged in different lengths and stepped.

Abstract: To introduce wire coils into stators of electric machines, improved isertion strips are proposed. To make the production of the insertion strips (1) cheaper and, in particular, to make it possible to use them for the joint insertion of interconnected coil groups, the insertion strips (1) are made of plastic. They consist of two elastically spreadable tongues, in which guide lamallae (15) made of spring steel are embedded. A foot part (4) is molded on one end of each tongue for releasable mutual connection and for attachment to an insertion tool (E). The foot part adjoins a parallel region of the tongues, which in turn adjoins the spread region of the tongues with an increasing distance between them up to the tongue tips (12).Crosspins engaging into corresponding holes in the adjacent tongue of the next adjacent insertion strip block the wire passage between the strips.

Abstract: A working process for the winding of stators (1) of electric motors, in which the coils (12) are inserted between two spreadable elastic tongues (4a and 4b) of draw-in needles and are introduced into the stator grooves (2) in this way and the coils (12) are interconnected according to the polarity before being drawn-in, is improved in terms of its applicability to small and very small-size motors and of greater economy.

Abstract: A molding device to flatten stator coil winding heads by thrusting a hollow forming die with a convex head against draw hooks holding the other side of the winding heads.
