摘要:
Device for compensating the feed tension in four-for-one twisting spindles in which a doubled yarn is unwound from a rotating unwinder which rotates by following the unwinding of the feed yarn, in which the yarn re-ascends a re-ascending internal axial cavity in which a compensator device is inserted, which lengthens and shortens the run of the yarn at its interior as a function of its tension.

It is an object of the present invention to provide a spinning machine having yarn slack eliminating device provided therein with an electromagnetic tensor capable of realizing a stable rotation resistance with respect to a yarn slack eliminating roller of the yarn hooking member, and capable of forming a package of stable quality. The yarn slack eliminating device includes a rotating and driving source (25), a yarn slack eliminating roller (21) which is rotated and driven by the rotating and driving source (25), and a yarn hooking member (22) which is mounted on the yarn slack eliminating roller (21) such that the yarn hooking member (22) can relatively rotate concentrically with the yarn slack eliminating roller (21), the yarn slack eliminating roller (21) is provided with magnetic field forming means (34) by electromagnet so that a magnetic field is applied to the yarn hooking member (22), a rotation torque is generated between the yarn slack eliminating roller (21) and the yarn hooking member (22) by the magnetic field generated by the magnetic field forming means (34), and the rotation torque is controlled by input control to the electromagnet.

The invention concerns a method wherein at least one yarn is unwound from at least one bobbin (2) by means of a baulk (10). The unwinding speed is developed and, in co-ordination, the other related parameters of the transformation process, based on a quantity representing the amount of yarn still wound on at least one of the bobbins (2), so that said unwinding speed remains within the limits imposed by the unwinding conditions.

Eine Fadenbremse mit einem im wesentlichen rohförmigen Bremsengehäuse (1), in dem eine kapselförmige Bremspatrone (11) angeordnet ist, die erste und zweite teleskopartig gegen die Kraft einer Feder gegeneinander verschiebbare Hülsenteile (12, 13) aufweist, die im wesentlichen kugelige bzw. kalottenförmige, entgegengesetzt gerichtete Endabschnitte zur Bildung von Bremsflächen haben, die gegen im Bremsengehäuse starr und/oder in Achsrichtung verschiebbar angeordnete Bremsringe (4, 14) anliegen, deren Abstand voneinander veränderbar ist, ist dadurch gekennzeichnet, daß in das Bremsengehäuse (1) koaxial ein Führungsrohr (8) mündet, das einen in unterschiedlichen Höhenstellungen in dem Bremsengehäuse (1) arretierbaren, federbelasteten Stützkörper (5) trägt, und daß innerhalb dieses Führungsrohres (8) ein in mindestens zwei Positionen gegenüber diesem Führungsrohr positionierbares Fadeneinlaufrohr (16) verläuft, dessen inneres Ende den Bremsring (14) trägt, der federbelastet an dem Stützkörper (5) abgestützt ist.
