Abstract: In a method for manufacturing metal bodies, e.g., stators for electric motors, a stack of sheet metal parts (14), which have thermally-curable adhesive layers provided therebetween, is guided over a mounting mandrel (11) of a tool, and/or is held by an external fixture (25). The stack is then heated to cure the adhesive layers while applying pressure thereto, thereby forming the metal body. In the course of the method, at least one of the applied pressure, the temperature of the stack, and/or the height of the stack is measured. A prescribed height of the stack is adjusted by performing a temperature-pressure control. The present system and method enables efficient and precise production of stators, is self-learning and enables the measurement, regulation and recording of all manufacturing parameters in the course of the manufacture of each individual stator. In particular, all manufacturing parameters can retrospectively be associated with an individual stator.

Abstract: A process for producing metal bodies, in particular for the production of stators for use in electric motors, has a plurality of steps. Firstly, a stack of a plurality of sheet metal parts is introduced into a cavity of a tool, with thermally curing adhesive layers being provided between the sheet metal parts. The stack is then heated to effect curing of the adhesive layers, forming the metal body. During heating, a pressure is applied to the stack. At least one of the following parameters is measured during the process: applied pressure, temperature of the stack, height of the stack. A prescribed height of the stack is set by use of a temperature-pressure control. The BPS™, BPS-Backpaketiersystem™ or Backpaketiersystem™ according to the invention makes efficient and precise production of stators possible, is self-learning and allows measurement, regulation and recording of all production parameters during production of each single stator.

Abstract: An essentially elongated strip is formed for manufacturing a ring-shaped element of an electrical machine. The strip has an electromagnetic effective area which is oriented perpendicularly to an axis of rotation of the ring-shaped element. The strip is essentially elongated, and has segments which are separate from one another and together form the effective area of the element. Adjacent segments are directly connected in each case by a web which is integrally formed on the outside of the element. The web is formed in such a way that it absorbs an elastic deformation during the bending of the strip, whereas the segments remain essentially free of elastic deformation.

Abstract: The apparatus for the manufacture of leno fabrics (1) in a weaving machine comprises a needle bar (3) for ground threads (13), at least one insertion element (4) for leno threads (4) and means for the insertion of weft threads (12). A pivotal arrangement (5, 6, 7) is connected directly to a main drive (51) of the weaving machine. The insertion element and the needle bar can be moved by means of this pivotal arrangement, so that the movement sequence which is required for the ground thread and leno thread results.

Abstract: A carriage for changing a harness or heald frame on a loom has a frame with a device for offering up the warp beam, a framework which includes a carrier mounted on the frame, and devices mounted on the carrier for offering up the warp stop motions and the heald shafts. Relative movement between the offering-up device is thus prevented due to the fact that the devices are mounted together on the carrier.

Abstract: A loom frame comprises side wall assemblies (9) on the narrow sides of the loom (1) and cross-members (13-16) interconnecting the side wall assemblies (9) and extending parallel to the long sides of the loom. The side walls (9) of the frame (8) are each in at least two parts (10, 11) secured to one another by at least one connecting bar (12). The same side wall parts (10, 11), but different connecting bars (12), flanges (121, 122, 125) and rests (123, 124) can be used to construct different loom frames. Different frames can therefore be produced at reasonable manufacturing costs from just a few variable parts.

Abstract: The warp yarn tensioner and warp yarn stop motion are mounted on a supporting and adjusting device of the loom so as to be adjustable together. The supporting and adjusting device includes a tube on which the tensioner and stop motion are mounted via support arms and cantilever beams. The support tube is adjusted relative to the loom frame by a single adjusting mechanism having an adjusting spindle which can be rotated in order to cause rotation of the tube. The warp yarn tensioner and warp yarn stop motion can be pivoted together about the axis of the support tube. The stop motion may also be adjusted vertically by means of a supporting device and can be pivoted about a pivot by means of a separate adjusting spindle.

Abstract: In an air jet weaving machine having: a picking nozzle (61, 62) outside the shed (15); and a weft yarn deflector (7, 90, 23) disposed between such nozzle and the shed (15) and operative to keep the weft yarn (5) away from the shed in response to a machine stop signal caused by a disturbance, a conveying line (22) for the deflected weft yarn (5) is received in the sley (10). The conveying line (22) is closed at its entry end by an end member (24) into which a funnel (23) of the weft yarn deflector leads. A receiver (30) having a suction or intake duct (32) is disposed at the exit end of the conveying line, the duct entry aperture being so dimensioned that the exit aperture of the conveying line (22) leads freely into the extraction or exhaust duct (32) in all positions of the sley (10).

Abstract: The cloth take-up device comprises a pressing device having a flexible pressure hose which is connectable to a pressure source and which presses a presser on to the cloth take-up roll. The pressure applied by the presser to the roll can be varied in a simple manner by variation of the pressure in the pressure hose and adapted to varying operating requirements. Delicate materials are taken up gently when a pressing roll driven at the peripheral velocity of the take-up roll is used.

Abstract: In a weft yarn storage device for weaving machines a cover (13) extending over approximately 120.degree. is provided above a rotating disc (2) which receives the yarn deposit (8). The cover (13) is secured against rotation by a bearing (14) and acts on the disc (2) by merely a slight pressure produced by its own weight. An ordered yarn deposit (8) is therefore produced. The speed of the disc (2) and the speed at which the nozzle (6) feeds the yarn (7) are so adapted to one another that the yarn deposit (8) extends at most as far as the intersection (42) of the tangent (43) with the disc (2) (center line (40) of the support surface (5)). The nozzle (6) is disposed directly on the leading edge (21) of the cover (13). A very reliable yarn entry between the support surface (5) and the cover (13) is therefore provided, as is also an orderly takeoff of yarn from the support surface (8) starting at (42).

Abstract: The heddle drive is coupled to the transverse beam of the heddle so that the path of movement of the heddle and the direction in which the drive force is applied run parallel to each other. As a result, the transverse beams need not be especially strong. Further, the longitudinal beams may be constructed in a light weight manner since no drive forces are transmitted to these beams. The resulting heddle has a relatively small mass and the drive is especially suitable for high speed weaving machines.

Abstract: The device for the storing of filamentary material contains a thread storage and a feed nozzle associated with it, the thread storage having a thread carrier which rotates past the feed nozzle and the feed nozzle being arranged fixed in position and rigid; and the depositing of the thread (S.sub.1, S.sub.2, S.sub.3) on the thread carrier takes place in the form of thread packages (P.sub.1, P.sub.2, P.sub.3) which consist of partially superimposed turns so that the length of the thread package (P.sub.1, P.sub.2, P.sub.3) and thus of the entire storage can be kept small, so that the storage is particularly suitable for looms, especially when using so-called mixers. The thread carrier is preferably covered by a small plate at the point of the formation of the thread packages, and the thread packages are deposited in the space between the thread carrier and the plate.

Abstract: A method of driving shuttles through sheds formed by warp yarns of a wave-type loom in which a transport edge of the shuttles is lubricated before entrance into the warp yarns, and a wave-shed loom for carrying out the method of driving the shuttles.

Abstract: A strip of snow is applied to a support surface which is to be drained, and covered with a quick-setting concrete. When the snow melts after setting of the quick-setting concrete, the space between the support structure and the set concrete which was previously taken by the snow serves as a draining channel. The apparatus for producing the channel includes a snow-making machine, a spray nozzle for the snow, and a spray nozzle for the quick-setting concrete.
