    摘要: Fiber material is conveyed over a sieve-like surface to remove dust from material. The fiber material is thereby exposed to a suction airstream which is guided through the sieve-like surface and which is guided away from the fiber material at an acute angle which is formed opposite to the fiber transport direction. The fiber material may be aligned in parallel before it is exposed to the suction airstream. In order to orient the suction airstream at the desired acute angle relative to the fiber transport direction, the fiber material is guided over sieve orifices which are inclined at the acute angle opposite to the fiber transport direction.

    摘要: To end or start the spinning operation on an open-end spinning unit by means of a switching device with which the connection to a spinning element or a delivery channel is alternately unblocked and blocked during the reversal of a switching device, the fiber flow is taken out of the region of the particular fiber path to be blocked, and only then is this region blocked. To influence the fiber flow, the volumetric flow rates of suction air flowing through the switching device are controlled. The switching device (6) has at least one closing member (60) with a first orifice (61) which leads to the spinning element (1) and the cross-section of which is enlarged geometrically in a discontinuous manner in the direction of the orifice opening, and with a second orifice which leads into the delivery channel (51) and the cross-section of which is reduced geometrically in a gradual way in the direction of the orifice closure.

    摘要: The coating of the pressure roller (3) of a drawing roller frame for spinning frames comprises an outer layer and an inner layer fixed to the core of the pressure roller. The outer layer is thinner and harder than the inner layer and is embodied as an endless belt (1) which loosely surrounds the inner layer such that the belt can be displaced in relation to the inner layer. In order to improve the running of the belt, the belt is guided over a deflector rail (2), the cross-sectional area (u) of the rail being wider than the average staple length of the fibre material (F) drawn on the drawing roller frame. Furthermore, the belt is designed in such a way that it comprises a double thread interlining, one thread interlining being wound counter to the second thread interlining such that the threads of one thread interlining cross the threads of the second thread interlining.

    摘要: During a jet spinning method, the rotating fibre ends or the subsequent wound fibres of the spun yarn (70) cause a spinning tension Fs. In tests, a direct correlation has been established between the spinning result and the spinning tension Fs. The aim of the invention therefore is to provide a method for spinning yarn in a jet spinner that permits an ideal spinning tension Fs despite high spinning speeds, thus achieving an optimal spinning result, in particular with regard to the yarn quality. According to the invention, a jet spinner is operated with a spinning tension Fs
