Abstract: To improve the breaking of a roving between a pressing finger bed and a fully wound bobbin preliminary to a bobbin change, the roving is initially wound around the tube above the upper cone and an unwound roving reserve is formed from at least a half turn on the upper winding cone and the body. A false twist is generated to provide a weakened region so that the roving has a first segment extending from the upper edge of the upper winding cone to the lower edge thereof, a second segment extending to the weakened zone and a third segment extending from the weakened zone to the pressing finger bed. The false twist increases the number of twists per unit length in the first segment and decreases the number of twists per unit length in the second and third segments. The pressing finger is moved along the bobbin periphery and the roving is broken at the weak spot by further movement of the pressing finger relative to the bobbin.

Abstract: In the case of ring spinning with condensing devices there is a risk that the yarns of the individual cops have a varying degree of hairiness. This can result in faults in the end product, for example a woven fabric. In order to avoid such faults, the ring spinning machine is connected to a monitoring station, in which the yarns are automatically monitored for hairiness; the cops, based on the monitoring results, are then automatically sorted.

Abstract: On a textile machine, arL empty spool (12) is conveyed along a multiplicity of spool stations (1) situated next to one another. In a predetermined position relative to a grasping apparatus (3) the said empty spool (12) is stopped and is picked up by said grasping apparatus (3), and held by its circumferential surface. After its being lifted by the grasping apparatus (3), the spool (12) is retained in an axial alignment. This retention is discontinued, before the spool (12) is released at the spool station (1) where it is required. For the execution of this procedure, a retaining arrangement (8), composed of stopping devices (4 and 5), is provided for the spool (12) which is held by the grasping apparatus (3). The retaining arrangement (8) idles in a location outside of the transport path which the empty spool (12) will occupy when held.

The roving reserve between the fastening turns and the pressing finger bed is then partly unwound to form a weak spot along the roving reserve and the pressing finger bed is then moved a certain amount along the bobbin periphery and the roving is broken at the weak spot by a further movement of the pressing finger bed.

Abstract: When a full bobbin signal from a counter CCM counting the number of rotations of the front roller (3) is output, the control element (28) outputs a signal directed to the control motor (M2) of a unit (29) for reciprocating a bobbin rail (10). As a result, the rotation of the control motor (M2) is combined with the rotation of a differential gear (14 ) connected to the main motor (M1), so that a reciprocating movement of the bobbin rail (10) after the full bobbin state is obtained which is faster than that obtained during a usual taking up operation of the roving, which causes the roving to be wound on the bobbin in a much coarser state than usual. A limit switch (LSP) detects a predetermined desired position of the bobbin rail (10), and the control element (28) outputs a signal directed to the unit (29), whereby the main motor (M1) and the control motor (M2) are stopped.

Abstract: A spinning apparatus winds a strand onto a yarn package by relatively rotating a flyer and the yarn package about an upright axis so as to wind the strand in a succession of turns around the package by a flyer finger movable axially relative to the package. Each successive layer of turns is shorter than the preceding one so that the finished package has an axially upwardly tapered upper end. After substantially completely forming the package the rotation is generally stopped to leave the flyer in a position with the finger below the upper end of the last layer of turns formed on the package. Then the package and finger are relatively axially moved until the finger is generally at the upper end of the first layer of turns formed on the package. The flyer and package are then relatively rotated forward, that is in the same direction as when the package was being formed, through at least one half revolution about the axis so as to form a loop of the strand around the upper package end.
