Abstract: The present disclosure discloses a process for knotting roving packages, comprising steps of: arranging a plurality of roving packages in a single layer or multiple layers; classifying all roving packages into at least one group of roving packages; selecting, from each group of roving packages, two roving packages as a starting roving package and an ending roving package; successively connecting all roving packages in each group of roving packages from the starting roving package to the ending roving package; and, connecting an inner fiber of a roving package other than the starting roving package and the ending roving package in each group of roving packages to an outer fiber of a previous roving package and connecting an outer fiber of this roving package to an inner fiber of a next roving package, or connecting an outer fiber of a roving package other than the starting roving package and the ending roving package in each group of roving packages to an inner fiber of a previous roving package and connecting

Abstract: Disclosed herein is a yarn plying apparatus which is able to ply two or more than two yarns, for example, a natural yarn, a synthetic yarn or a metal filament. In the present invention, the yarn packages are arranged in a radial shape at a regular interval on the base. The yarns are plied at the plying guide hole formed just above the center of the base, so the length and angles to the plying hole of the yarns moving to the plying hole are constant, whereby the constant tensile force can be maintained. Even when the thusly plied yarns are covered or twisted, the constant twisting can be obtained.

Abstract: A yarn feed assembly for directing yarn from a wound yarn source to a yarn feed tube having a frame member positioned adjacent to the wound yarn source and defining at least one elongate interior chamber. The yarn feed assembly has a weighted member slideably received in the elongate interior chamber such that, upon pulling one yarn off of the wound yarn source, through a bore of the weighted member and into the yarn feed tube, the weighted member is axially movable along a longitudinal axis of the frame member such that the bore of the weighted member is axially movable about and between a bottom end and a top end of the elongate slot in response to tension applied to the yarn as a result of yarn hang ups on the wound yarn source.

Abstract: In a cable guide for fibers, particularly carbon fibers, which are combined into cables and extend in a transport direction in a transport plane, characterized in that the cable guide comprises a plurality of individual pins for separating said cables consisting of fibers, it is provided that the pins relative to the transport direction of the cables are inclined in the transport direction and together with the transport plane include an angle from 20° to 70°.

Abstract: A core cabling device and method provides a first supply of yarn supported by a structure having a bore, such as a yarn cone, and a second supply of yarn that is then directed through the bore. As the first and second yarns are fed simultaneously, the first yarn winds, at least loosely, about the second yarn. It will become apparent that more than two yarns may be cabled together in such a manner.

Abstract: An overend unwind system for unwinding tacky elastomeric fiber threads such as uncoated spandex thread, capturing the ballooning affect of the thread as the thread leaves the spool, applying a first-stage tension control on the thread adjacent where the thread leaves the spool, feeding the unwound thread to a nip in a downstream process, and applying a final tension increment to the thread adjacent where the thread enters the downstream process. All thread guide surfaces encountered by the thread after leaving the spool, and while the thread is under designed operating tension, are moving surfaces, such that the tensioned thread thereby experiences a reduced level of drag as the thread traverses its path of travel from the spool to the downstream process.

Abstract: A method for unwinding tacky elastomeric yarn from one or multiple coiled yarn packages includes the steps of (a) removing tubular cores from each yarn package to expose the beginning end of the yarn strand at the inner diameter of the yarn package; (b) forming a terminal end of the yarn strand at a position along the length of the strand between the inner diameter and outer diameter of the yarn package; (c) when unwinding multiple coiled yarn packages, attaching the terminal end of the first yarn package to a beginning end of a next yarn package; and (d) unwinding by pulling the beginning end of the first yarn package in a generally axial direction to remove yarn from the inside of the package from the inner diameter toward the outer diameter. This method provides inside-out unwinding of a single package, or continuous unwinding of multiple packages of elastomeric yarn at a reduced overall yarn tension, and minimizes unwinding tension spikes.

Abstract: A tube holder on a creel receives a cardboard tube with a yam wound thereabout. The tube holder is preferably equipped with a tube stop at a non-feeding portion of the tube holder and a tube end protector which is preferably connected to the tube holder at a feeding end of the tube holder. The tube end protector is constructed at least partially out of a resilient material wherein the tube is placed over the tube end protector causing it to deflect until the cardboard tube is properly located on the tube holder wherein the tube end protector resumes its normal configuration and protects the line wound about the cardboard tube from any potential defects at the feeding end of the cardboard tube.

Abstract: A yarn tightening element for a weaving machine, comprising a passage (16) for a yarn (15) and a contact means (2) to transmit a tightening force to a yarn (15) moving along through this passage, the passage (16) being not bordered on at least one side of the plane of movement of the yarn (15) or comprises a boundary (14) that is interrupted across its width, so that a part of the yarn (15) running through from that side of the plane of movement, via the interruption (17), can be made to co-operate with the contact means (2). Said boundary is, for instance, formed by one or more fingers (14) directed downwards, while said interruption (17) of this boundary (14) is formed between the extremities of each finger (14) and a part (8) of the yarn tightening element. Such a yarn tightening element can be placed on a yarn very easily and quickly by means of a hooking on movement and be removed again by means of an equally simple hooking off movement.

Abstract: At least one thread tension sensor for each thread is provided on a winding machine. The actual value of thread tension is measured for each thread. The actual value is compared with a specified value in a comparator device and, in the event of a deviation being determined between the actual value and the specified value, a drive motor is actuated to adjust the thread brake of the thread concerned. This arrangement allows for the maintaining of a constant thread tension by a control circuit. The thread tension sensor can be used not only to control the thread tension, but also to monitor the specified thread tension range, and as a thread break monitor.

Abstract: A device for tensioning and drawing back warp yarns brought from a creel to a weaving machine. The tensioning and drawing back device keeps tension and if necessary draws back warp yarns (2) led from a bobbin (1) to a weaving machine. A supporting body (6) has a curved friction surface to support the warp yarn (2) between the bobbin (1) and the weaving machine. A first (7) and a second tensioning element (8) exert a tensile force on the warp yarn (2), respectively, in front of and behind the curved friction surface (6). The tensioning elements (7), (8) can be suspended from the warp yarn (2) and for example only through their own weight may exert this tensile force. This device easily draws back the warp yarn (2) out of the weaving area. The replacement of a bobbin (1) occurs without interruption or disturbance of the weaving process.

Abstract: A yarn unwinding tension stabilizer capable of stably unwinding a yarn from various types of yarn suppliers in such shapes as cheese and cone so as to effectively cope with such drawbacks as slide of wound layers on a yarn supplier and slippage of yarn loops therefrom due to the ballooning of an unwound yarn and so forth and a yarn unwinding tension stabilizing apparatus for a warping creel capable of simultaneously setting said stabilizers on the multiple number of the suppliers suspended on the warping creel in an easy operation. The tension stabilizer (3) is arranged by disposing the plurality of elastic wiring materials (2) on the opening (10) of the supporting member (1) in such a manner that said materials convavely curve towards the center of said opening and overlap one another. The frame, in which the plurality of said stabilizers are aligned in rows, is arranged such that it is horizontally movable as a whole.
