Abstract: The invention relates to a device and method for removal of yarn, especially faulty yarn, from an inter-storage at an operating unit of a textile machine. The yarn to be removed from the drum of the drum inter-storage is moved from the drum by a force exerted in the direction of the longitudinal axis of the drum towards the end of the drum and/or outside the drum, from where the yarn is sucked off.
Abstract: A method for producing a multidirectional contexture made of fibers, in particular carbon fibers, in which a unidirectional contexture web is wound at an angle about a plate to form a coil, wherein the plate is provided with a device for compensating friction, and the coil is pulled off from the plate. In order to provide improved pulling of the fibers off a plate a cascade guide is being used, which is disposed at the end of the plate and which comprises a laterally extended wedge.
Abstract: A device (6) for holding and centering yam tubes (3) for processing while in a vertical orientation on transport disks (2), e.g., for removing a yam remnant (4) at a tube cleaning station. During such processing, the tubes are fixed in place by means of a height-displaceable centering arbor (12) coupled with a circuit arrangement which causes the operating height (h) of the centering arbor (12) to be automatically matched to the length of the respectively provided tube (3). An arresting arrangement (20) assure that the centering arbor (12) is securely fixed in place at each of its operating heights (h).

Abstract: A device for centering tubes during their processing, for example in a tube cleaning station of a textile machine. In a textile machine provided with several batches of tubes of differing length, diameter and/or material, which cannot be processed together in known cleaning devices, the present device has a rotatably seated holder with at least two differing centering devices adapted for different tubes for selective positionability relative to the tubes to be centered according to sensor devices which detect the differing physical characteristics of the tubes.
Abstract: The bobbin feeding system of the automatic winder comprises a bobbin feedback line from the automatic winder which is branched off into a residual-yarn bobbin conveyor line and an empty-bobbin conveyor line, each conveyor line being joined with each other and connected to the empty-bobbin discharge line, and a bobbin stripper for removing residual yarn from the bobbin which is mounted on the residual-yarn bobbin conveyor line, thereby enabling smooth conveyance of bobbins.
Abstract: An apparatus for removing yarn remnants from a cop tube, especially a cop tube located a caddy, includes a device for removing yarn remnants from the cop tube. An elastically deformable energy storing device is disposed in the vicinity of the bottom of the cop tube. A holder for the yarn remnant removing device is movable along the cop tube and toward the energy storing device for storing potential energy.

Abstract: A machine for processing textile tubes with yarn residue and comprising a device for removing the yarn residue from the textile tubes and including jaws, an element for opening the jaws, and an element for closing the jaws into the yarn residue with respect to a diameter and conicity of the textile tubes so as to minimize a pressure exerted by the jaws on the textile tubes. The machine further comprises a guide for guiding the textile tubes and an element for moving the guide member of the guide in opposite directions between the jaws. The opening element is formed to open the jaws in response to the guide member being moved in one of the opposite directions, and the closing element is formed to close the jaws in response to the guide member being moved in the other of the opposite directions.
Abstract: The device for removing yarn residue for textile tubes including jaws; a mechansim for opening the jaws including a plurality of rollers and biased wedges supporting the rollers and the jaws, stringers arranged to engage and push apart the rollers and therefore push apart the wedges and the jaws, and a pawl device for guiding the stringers into engagement with the rollers for moving apart the jaws; a mechanism for closing the jaws which biases the jaws to close towards each other; a guide member formed so as to center the textile tubes relative to the jaws and having two tapered tips formed to hold the textile tube longitudinally therebetween; and a mechanism for moving the guide member in opposite directions between the jaws reciprocally. One of the tips is arranged to receive the yarn residue retained by the jaws and the other tip is formed on the guide member.
Abstract: A system for transporting various kinds of cops to an automatic winder which includes a number of winding units. The winding units are divided into a plurality of winding sections, whereby a kind of cops from a spinning frame are supplied to and unwound on one of the sections. A cop supplying passage and an empty bobbin returning passage are provided between the sections and the spinning frame so as to form a closed loop.
Abstract: Apparatus for stripping residual yarn from textile bobbins using an oscillating feed drum to feed bobbins singly to a position offset from the stripping position. Two pairs of centering forks transport the fed bobbin to a position in axial alignment with a plunger. Mounted with one pair of the centering forks is a pair of stripping blade support members, each having a pocket and a stripping blade having a plurality of symmetrically disposed stripping surfaces being slidably inserted in the pocket.
Abstract: Means for stripping residual yarn from spent spinning tubes effectively, and while protecting the physical condition of the spinning tubes as they are handled for stripping, is provided by combining means for aligning a spinning tube axially for stripping with means for applying a pair of stripping blades oppositely and transversely to the body of an aligned spinning tube adjacent the base thereof, and means acting at the tip of an aligned spinning tube for pressing the same axially between the applied stripping blades, while additionally arranging means for relieving the stripping blade application whenever the pressing means is resisted by a stripping force sufficient to threaten spinning tube damage.
