Method and Apparatus for Warping the Warp Yarns for Weaving and Knitting Machines - Specification

Sep 21, 2026

Upload by Eliana

Method and apparatus for warping warp yarns for weaving and knitting machines are disclosed, including a process in which one group of warp yarns is pulled individually from bobbins on a bobbin creel and warped together on a single warp beam. The yarn is a glossy multifilament synthetic fiber pre-drawn during manufacture and permanently set by further drawing, then cold-drawn under controlled tension by two yarn drive stages. A coordinated warping apparatus uses an undriven bobbin creel and multiple yarn drive devices with stepwise increasing speeds to produce the final drawn length.

Title of the Invention Method and Apparatus for Warping the Warp Yarns forWeaving and Knitting Machines ## 2. Claims (1) A method for warping the warp yarns for weavingand knitting machines characterized by pulling out one group Digitized by the Internet Archivein 2017 —2— of warp yarns individually from bobbins on the bobbin creeland warping them with one warp beam,where (a)the yarn usedas the warp is a glossy multifilament synthetic fiber yarndrawn in advance to 60-70%of the final drawn length at thetime of manufacture and permanently set to the desired finaldrawn length by further drawing,(b)these warp yarns 3 arepulled from the undriven bobbins on the bobbin creel at aspecified speed by a first yarn drive device 6,(c)these warp yarns are then pulled at a faster speed than the specifiedspeed referred to above by a second yarn drive device 14and/or a driven warp beam 13 and stretched by only about30-40%of the final drawn length by cold drawing with atension load,and(d)the warp yarns 13 thus drawn to theirfinal drawn length are warped on warp beam 13. (2)The method of Claim 1,where the final drawn lengthis produced by two or more yarn drawing work zones A,B, C. (3) The method of Claim 1,where the winding tensionof warp beam 13 is used for at least the last part of thedrawing process. (4) A warping apparatus for warping the warp yarns forweaving and knitting machines that pulls off one group ofwarp yarns individually from bobbins on the bobbin creeland warps them with one warping beam,and which includesa bobbin creel provided with undriven bobbins and a warping —3— machine equipped with a drive device for the warp beam,wherein the first yarn drive device having at least tworollers 7,8 is connected in common to all the yarns at the rear of bobbin creel1,and the drive speed of this firstyarn drive device is selected much slower than that of thesecond yarn drive device 14,also common to all the warpyarns and placed still farther to the rear of the creel. (5) The warping apparatus of Claim 4,where severalyarn drive devices 6,19,20,14,whose drive speeds increasestep-wise in the direction of travel of the warp yarns,areplaced in a queue. (6) The warping apparatus of Claim 4,where the yarndrive device with the highest drive speed and placed at theend of the queue is warping device 14. (7) The warping apparatus of Claim 4,where a drivemotor 9 capable of continuously changing speed is attachedto at least the first yarn drive device 6. (8) The warping apparatus of Claim 4,where the drivespeed of the first yarn drive device 6 is about 60 to 70%of the drive speed of winding 18 on warp beam 13. (9) The warping apparatus of Claim 4,where the differencein drive speed of the several yarn drive devices 6,19,20,14 placed in a queue is almost the same. ## 3. Detailed Description of the InventionThe present invention is a method for warping the warp —4— yarns for weaving and knitting machines of the type thatpulls off one group of warp yarns ind

FAQs

What core method is used to warp the warp yarns?

A method warps warp yarns for weaving and knitting by pulling one group of warp yarns individually from bobbins on a bobbin creel and warping them together on one warp beam.

How is the glossy multifilament synthetic fiber warp yarn prepared?

The yarn is drawn in advance to 60–70% of the final drawn length during manufacture and permanently set to the desired final drawn length by further drawing.

What distinguishes the warping apparatus of the invention?

The apparatus includes a bobbin creel with undriven bobbins and a warping machine with drive devices for the warp beam and yarn drives, where the first yarn drive device runs much slower than a second yarn drive device and may be organized as a queue with increasing stepwise speeds.
