The transporting assembly includes a cyclicly reversing endless belt which transports tube support members to and between a plurality of individual transport paths which each lead through a respective winding station of a textile winding machine. The individual transport paths each comprise a pair of endless belts which automatically draw tube support members onto the individual transport paths from the delivery path when the tube support members are disposed on the delivery path at the transport path at a predetermined height relative to the individual transport path.

Abstract: The present invention discloses a method of draw warping a plurality of partially oriented synthetic continuous filaments traveling in parallel side by side relation to produce denier variations randomly along the length of each filament and randomly from filament to filament. This is accomplished by transporting the filaments collectively through a draw zone defined between first and second filament engaging members and by imposing a common lengthwise stretching force simultaneously to the filaments with the draw zone while heating the filaments and, finally, by causing the filaments to slip randomly and draw non-uniformly on at least one of the filament engaging members.

Abstract: The invention to a yarn tension sensor, in particular for yarns traveling at high speed, to accurately ascertain even short-term yarn tension fluctuations. According to the invention, a yarn guide element is mounted on one head end of a plunger coil disposed in a magnetic field. A position sensor is disposed in the region of the plunger coil and detects even minimal changes in position of the plunger coil. These changes in position are reported to a controller, at whose output variations in current are generated and supplied to the winding of the plunger coil, the variations being such to compensate for the axial force generated by the yarn and acting upon the plunger coil, thereby making the plunger coil virtually motionless.

Abstract: A process and apparatus for treating yarn formed on an open-end spinning machine of the type wherein the yarn is drawn from a rotor through a navel and through draw-off rolls is provided. The yarn is guided from the navel to the draw-off rolls in a path at least a portion of which is inclined with respect to the axis of the navel and a false twist is applied to the yarn during its travel in the inclined portion of the path between the navel and the draw-off rolls. The yarn is permitted to untwist between the false twist application and the draw-off rolls in response to the applied false twist. The untwisting of the yarn causes fiber ends on the surface of the yarn to project outwardly in a hairiness or fleeciness producing manner. The false twist applying element can include a member which produces a rotating air stream about the periphery of the traveling yarn.

Abstract: The present invention provides an overlay for overlying an edge, corner, or other non-planar extent of an object. The overlay includes first and second longitudinal portions interconnected to one another to form an included angle of generally 90.degree.. The first longitudinal portion has a plurality of segments, each having opposite end walls which form channels between adjacent segments. Each channel extends from a front channel opening to a longitudinally offset rear channel opening. Due to the channels between the segments, the segments are free to move relative to one another as the overlay is manipulated to conform to the non-planar extent of the object to be protected. At least some partial overlap always obtains between adjacent pairs of the segments so that the overlay provides protection irrespective whether it is overlying a non-planar extent which is generally concave or generally convex in shape.

Abstract: A ball tension device for producing generally uniform tension in a traveling textile yarn, particularly in combination with a yarn storage and supply apparatus of the rotating drum type. A base portion has a yarn passageway with an upwardly facing annular ball seat. A ball freely rotatably rests on the seat to apply a force to a yarn passing over the seat and through the passageway. A ball retaining portion extends over the ball at an upward spacing sufficient to allow upward movement of the ball but insufficient to allow removal of the ball. These base and ball retaining portions project transversely from a mounting portion to provide a substantial open space to permit entry of a downwardly inclined traveling yarn. The ball retaining portion is imperforate to provide a cover for the ball and seat to shield the ball and seat from accumulation of lint. Similarly, the substantial open space around the ball and seat tends to minimize lint accumulation.
