    摘要: The method of producing an industrial yarn at a production speed of from 3000 to 6000 m/min includes melt-spinning a plurality of polyester filaments; stretching a thread made from the filaments by means of a delivery assembly (1) and a drawing roller system (2); providing at least one thread-braking device (3) including at least one deflecting roller (31, 32) between the delivery assembly (1) and the drawing roller system (2); deflecting and decelerating the thread between the delivery assembly and the drawing roller system by means of the at least one thread-braking device (3) and looping the thread only once around the at least one deflecting roller (31,32) of the at least one thread-braking device (3). The at least one deflecting roller (31, 32) is braked to a circumferential speed (v.sub.3) given by the following formula v.sub.3 =v.sub.1 +(v.sub.2 -v.sub.1)* F, wherein 0.5.ltoreq.F

    摘要: Method of controlling a variable in response to an error signal by comparing a signal correlated to and substantially proportional to the controlled variable with a reference signal corresponding to a set point value of the controlled variable. The reference signal varies substantially linearly with time until it reaches or at least closely approaches a limiting value which corresponds to the set point value of the controlled variable.

    摘要: In an apparatus for the spin-drawing, on multiple ends, of thermoplastic filament yarns on at least two pairs of godets (1, 2 and 1', 2'), their axes of rotation (7 and 8) are arranged skew with respect to each other in such a way that the axis of rotation (8) of the one godet (2) is arranged to be able to pivot within a plane (12) and the plane (12) forms an angle (.beta.) of 10.degree.-60.degree. with the plane (10). The arrangement according to the invention makes it possible for the first time to spin and simultaneously draw in an integrated manner on multiple ends.
