摘要:
Method of winding a wire (2) on a toroidal core (1) having a hollow hole, in which the steps of inserting one end of the wire (2) from one side of the toroidal core (1), pulling out the wire (2) projected from the toroidal core (1), winding the wire (2) thus pulled out around the core, and again inserting the end of the wire (2) under tension into the toiroidal core (1), are performed in a repeated manner, which further advantageously includes the step of cutting the end of the held wire (2) so that the length from the held position to the end of the wire (2) is a predetermined length before the end of the wire (2) is inserted into the toroidal core (1). Thus, the state of the end of the wire can be maintained always constant, thereby efficiently winding the wire by the above repeated operations.

Dans une unite d'enroulement avec magasin a fil d'une machine a enrouler, du fil tel que du fil de cuivre (45) alimente le magasin (42) et simultanement, l'enroulement d'un corps allonge tel qu'un noyau toroidal (49) pour bobine ou transformateur electrique se fait avec ledit fil de cuivre pendant la rotation de l'unite d'enroulement. Pour enrouler le noyau (49) directement en une operation, le fil descend dans le magasin (42), en sort par le fond, et est maintenu contre le noyau (49). La section de la chambre d'approvisionnement du magasin est substantiellement plus haute et plus large que le diametre du fil, et pendant l'operation d'enroulement l'approvisionnement en fil est stationnaire par rapport au magasin tandis que ce dernier se vide par le fond.

Bei einer Bandage (19) für Wickelköpfe (20) von Läufern (1) elektrischer Maschinen, im wesentlichen bestehend aus einer Kunststoffmatrix mit darin eingebettetem Fasermaterial, wird die Bandage (19) durch Aufwickeln eines Faserbandes (15) auf den Wickelkopf (20) gebildet. Die Kunststoffmatrix besteht aus einem thermoplastischen Kunststoff. Weiter wird ein Verfahren zur Auftragung des Faserbandes auf den Wickelkopf einer elektrischen Maschine beschrieben.
摘要:
In a method of joining an end fitting into a pressure vessel, which is built up by composite material by a winding procedure, the peripheral surface of the end fitting (2) is shaped with a plurality of protrusions (3) distributed over the surface. The fibers are so wound, that the portions of the fibers or the bunches of fibres (4) which are applied along peripheral arcs of the end fitting are placed on and fixed by the protrusions.

An apparatus for fabricating a unique nonwoven fabric which has the appearance of a woven fabric includes a supply station for parallel warp yarns, a support structure for orienting the parallel warp yarns into a cylindrical orientation, a weft yarn applicator for wrapping weft yarns around the cylindrically oriented warp yarns after an adhesive scrim has been overlaid onto the warp yarns, a heating station for activating the adhesive and a cooling station for setting the adhesive, and a cutter for severing the cylindrically formed fabric laminate so that it can be flattened and wrapped onto a take-up roller. The weft yarn applicator including a rotating drum wherein a plurality of spools of weft yarn material are mounted in circumferentially spaced relationship and a tensioner is provided for applying the weft yarn material around the warp yarns in a predetermined tension which may be the same as, greater than, or less than the tension in the warp yarns.

A woven endless tire reinforcing belt (14) for a pneumatic tire (10), wherein the reinforcing belt (14) comprises a first belt portion (15) having a width W1, said first portion (15) comprising at least one coated continuous cord reinforcement (18) woven in a zig-zag pattern, and at least one additional belt portion (17) having a width (W2), W2 being substantially different from W1, said additional belt portion (17) being woven from at least one coated continuous cord reinforcement (18), said additional belt portion (17) being positioned adjacent the first belt portion (15) and substantially centered therewith, whereby said endless tire reinforcing belt (14) has increased uniformity of stiffness from one edge to the other. Also provided is a method for weaving such a reinforcing belt (14).
