摘要： A fiber bundle condensing device (10) of a spinning machine (100) includes a condensing unit, a plurality of countershafts (20), a countershaft driving motor (103), and a shaft coupling (70). The shaft coupling (70) couples the countershafts (20) with a bolt (80). The fiber bundle condensing device (10) further includes a detected portion, a rotational position detector (30), a controller (40), and an operation unit (41). An operational range is defined as a range where a rotational position of the shaft coupling (70) is located and the bolt (80) used for a coupling main body (73) is operable from a front of the fiber bundle condensing device (10). The controller (40), when the stop command is input, controls the driving of the countershaft driving motor (103) such that the shaft coupling (70) is located in the operation range at a time when the countershafts (20) stop rotating.

摘要： A draft apparatus (11) in a spinning machine is provided with a front bottom roller (12), a middle bottom roller (13), a back bottom roller (14), and motors (15, 16a, 16b, 17a, 17b) for independently driving the rollers (12, 13, 14). Lock means (21) inhibits the back bottom roller (14) from being rotated at least in a forward rotating direction, at least for a predetermined period after a spinning stop of the spinning machine. Accordingly, it is possible to inhibit a fiber from being excessively fed due to a torsional return of the bottom roller under the stop period of the machine, and it is possible to suppress yarn unevenness at a time of starting (Fig. 1).

摘要： The invention relates to a ring spinning frame comprising drawing systems that are provided with several drawing rollers which can be driven at speeds causing predetermined drawings by means of main drawing system drive units. Auxiliary drawing roller drive units are assigned to the drawing rollers at a distance from the main drawing system drive unit. The inventive ring spinning frame is characterized in that drawing rollers (2, 3, 4) are equipped with several auxiliary drawing roller drive units (12) which are distributed along the length of the drawing system (1) and impinge the drawing roller with torque that at least reduces torsion thereof such that torques preventing or at least reducing torsion of drawing rollers can be introduced also between the ends of very long drawing rollers without increasing the division of the ring spinning frame at said points or interrupting the sequence thereof and without having to use synchronous motors.

摘要： The invention relates to a method for starting a drawing frame (1) used for drawing a fiber bond (2). Said drawing frame (1) comprises at least one pair of forward rollers (3) and a pair of rear rollers (4) that is provided with a clamping line (5), one end (6) of a fiber bond being provided for starting the drawing frame (1). According to the invention, said end (6) of the fiber band enters the clamping line (5) of the pair of rear rollers (4) during starting of the drawing frame (1) only once the acceleration response process in the rotary speed curve of the pair of forward rollers (3) and in the rotary speed curve of the pair of rear rollers (4) has been completed.

摘要： A locating frame (27) for drawing and compacting units of a pair of adjacent spinning stations in a spinning machine where each drawing unit has a pressure roller (12) which supplies the bundle of fibres to the compacting unit and which rotates a pressure roller (19) of the compacting unit, by means of a belt transmission (20). The frame comprises: two pairs of seats (29) for housing and keeping parallel and spaced apart two axles (21, 22) on which the pressure rollers (12) of the drawing units and the pressure rollers (19) of the compacting units of the two adjacent stations are mounted rotatably, longitudinal arms (42) acting on the axles (21, 22) in order to keep the pressure rollers (12, 19) of the same spinning station aligned longitudinally, and transverse arms (43) for keeping the transmission belts (20) of the two adjacent stations, respectively, aligned with ring gears (25, 26) fixed for rotation with the pressure rollers.
