Abstract: The present invention provides a manipulator on a sliver can transport carriage which can travel along the spinning positions of a spinning machine to enable the manipulator to take up a leading end of sliver at a defined position on a sliver container and guide the sliver end to a sliver supply location of a spinning position.

Abstract: A sliver dividing device in a textile machine for a sliver travelling in a given direction comprises a sliver divider for dividing the sliver into at least two strands to be delivered to a work station for further processing. The sliver divider is movable in a direction substantially perpendicular to the given direction. In a preferred embodiment, the device includes guide walls for guiding the sliver with the sliver divider being disposed between the guide walls. In another preferred embodiment, the sliver divider is further rotateable about a pivot shaft and the guide walls are moveable and/or rotatable.

Abstract: A sliver feeding and opening device includes an outlet opening for passage of separated fibers to the rotor and an intake opening for the intaking of sliver to be separated into fibers. An intermediate opening is disposed in the chamber of the housing of the device at a location downstream of the outlet opening and upstream of the intake opening. An air stream reduction conduit extends from the intermediate opening to the outlet passage. The intermediate opening and the air stream reduction conduit conduct air from a revolving stream of air which revolves in the space between the opening roller and the cylindrical wall of the housing of the sliver feeding and opening device to prevent the revolving stream of air from detrimentally interfering with the orderly feeding of sliver at the intake opening to the opening roller.

Abstract: A friction spinning apparatus includes first and second perforated drums forming a spinning wedge therebetween with a spinning zone. The drums are driven in the same direction with the first drum having a greater circumferential speed than the second drum and with the first drum rotating into the spinning wedge and the second drum rotating out of the spinning wedge. The drums define an imaginary line at a location at which the drums are closest to each other. First and second suction devices are disposed in the interior of the first and second drums. The suction devices each have an intake slit formed therein. The intake slits follow paths diverging from each another and from the imaginary line at least at forward ends thereof. The intake slits are directed against the spinning wedge and each discharge in the vicinity of the inner surface of a respective one of the drums.

Abstract: A method of producing a twisted thread from spinning fibers by friction spinning includes moving two friction elements of a friction spinning machine in opposite directions defining a spinning wedge therebetween, at least one of the friction elements having a perforated wall, feeding spinning fibers into the spinning wedge in a given direction with a transporting air current, continuously withdrawing a twisted thread from the spinning wedge in the given direction, sucking a first part of the transporting air current through the perforated wall of at least one of the friction elements, and sucking a second part of the transporting air parallel to the spinning wedge, parallel to the thread and opposite to the given direction in which the thread is withdrawn and the fibers are fed into the spinning wedge, and a device for carrying out the method.

Abstract: Means for positioning the end of yarn on a cross-wound bobbin on a textile machine. The machine has a traveling service mechanism that services the bobbins individually at winding heads of the machine. A yarn end take-in device in the form of a suction tube with a concave surface facing the bobbin and a nozzle against the bobbin searches for, takes in and draws off a yarn end from the bobbin. A yarn guiding device, in the form of an inclined slot in the suction tube or a pivoted guiding rod, guides the yarn end against a side of the bobbin. A yarn guide element on the winding head, on the creel or on the servicing mechanism is positioned with an oblique surface extending to an end adjacent the juncture of the bobbin side and bobbin tube to guide the yarn to the juncture for forming a yarn end reserve thereat.

Abstract: An OE friction spinning device having a fiber loosening device and device for forming a spinning wedge, improvement includes a fiber conducting channel having a wall, a device for generating a transporting air current in the fiber conducting channel for carrying fibers from the fiber loosening device to the spinning wedge, the wall having at least two openings formed therein being spaced from each other along the transporting air current for the passage of guiding air forming at least one guiding air stream parallel to the transporting air current in the fiber conducting channel.
