摘要： A festoon device includes a frame, which extends vertically, an upper pulley, which is rotationally supported by an upper part of the frame, and a lower pulley, which is rotationally supported by the frame below the upper pulley and is selectively moved up and down. The frame rotationally supports two auxiliary pulleys, which are arranged at a position closer to the frame than the upper pulley and the lower pulley. The festoon device is configured such that a wire is looped about the upper pulley and the lower pulley after being looped about the auxiliary pulleys.

摘要： A melt spinning device produces a plurality of multi-filament threads which includes a spinning apparatus, a cooling apparatus, a drawing apparatus and a winding apparatus. The drawing apparatus has a plurality of godet units entwined by threads, each of said units having a plurality of godets, which are axially rectified to a coil spindle of the winding device. The transition of the threads as yarn from the drawing device to the winding device is executed by a guide godet which is aligned axially crosswise to the godets of the godet units and under the drawing device, so that the threads can be guided by simple partial wrapping after rotation of the thread running plane of the yarn by 90°.

摘要： A detention unit is provided for retrieval of an elongated body (9), such as a cable. The unit includes two or more movable friction surfaces (1, 11) adapted to pull in the elongated body (9). The moveable friction surfaces (1, 11) are arranged relative to each other so that the elongated body (9) may bear or rest against at a part of at least two friction surfaces (1, 11) in a sequential manner. The part of the friction surfaces (1, 11) adapted to pull the elongated body (9) defines a arc section, and each friction surface is provided with a separate propulsion unit (3, 14).

摘要： Press rollers for being pressed respectively against wires are provided on an upper side of the wires while length-measuring rollers for respectively contacting the wires are provided on a lower side of the wires. A number of revolutions of each length-measuring roller is detected by an encoder, and an amount of actual feed of each wire is detected in accordance with its revolution number, and a pulse signal, representing its detection value, is sent to a comparison processing portion of a controller. In this comparison processing portion, the amount of actual feed of each wire, detected by the encoder, is compared with a predetermined feed amount of a feed roller beforehand given as an instruction to the processing portion, and if there is any difference between the two, an instruction is given to a servo amplifier, and the servo amplifier sends an instruction to a servo motor for driving the feed roller so as to rotate the servo motor in a normal or a reverse direction in accordance with this difference.

摘要： A friction thread feed device having at least two drums (5, 6) which are arranged spaced apart from each other and are partially wrapped by the thread (F), the drums being driven in the direction of travel of the thread (F) with a circumferential speed which is considerably greater than the thread removal speed. In order to avoid the layers of thread passing onto each other upon multiple wrappings on the drums and also in the case of threads of difficult shape, partitions (17, 18) which divide the drum outer surfaces into individual adjacent regions which are axially offset from each other are fastened in the region of the space between the drums (5, 6 ).
