Loading yarns into a textile machine

Abstract

The invention relates to an apparatus for presenting threads for loop-forming tools, arranged in at least one row, of a textile machine having a thread guide apparatus having at least one rotary element ( 4, 5, 20, 21, 30, 31, 40, 41 ) having at least one thread guide ( 20 a, 20 b, 21 a, 21 b 30 a, 30 b, 40 a, 40 b ), said thread guide apparatus being configured to lay a thread back and forth in two directions (HI, HR) in each case in front of a row of the tools in an entire stroke range (BG). The thread guide apparatus has at least two rotary elements ( 4, 5 ) arranged as a pair, wherein the rotary elements ( 4, 5, 20, 21, 30, 31, 40, 41 ) of a pair are arranged eccentrically with respect to one another and one above another in the axial direction, and wherein the rotary elements ( 4, 5 ) of a pair are drivable in opposite directions of rotation (R 1 , R 2 ). Each rotary element ( 4, 5, 20, 21, 30, 31, 40, 41 ) has at least one thread guide ( 4 a, 4 b, 4 c, 5 a, 4 b, 4 c, 20 a, 20 b, 21 a, 21 b, 30 a, 30 b, 40 a, 40 b ), configured as a driver element, for laying the thread in one of the directions (HI, HR).

1 . An apparatus for loading yarns into at least one row of stitch-forming tools of a textile machine, comprising
 a pair of yarn loader each having a pair of rotor rotating in opposite directions about a common axis and one axially above the other,   at least one yarn guide, on each of the rotors operable to lay a yarn back and forth in two directions along a full machine width in front of the row of tools, being formed as a driver element for laying the yarn in a respective one of the directions.   
     
     
         2 . The device according to  claim 1 , further comprising:
 a feeding device that supplies the yarn that is laid in a respective one of the directions to the tools.   
     
     
         3 . The device according to  claim 1 , further comprising
 a retaining device with two retaining elements that are near reversal points of the yarn spaced apart by the full machine width, the retaining devices each receiving the yarn laid by the yarn loader in a respective one of the directions and supplying it to the tools.   
     
     
         4 . The device according to  claim 1  wherein the rotors each have at least two yarn guides. 
     
     
         5 . The device according to  claim 1 , in that wherein the yarn loader comprises a number of pairs of rotors, the pairs being side by side with each pair laying the yarn over a respective stroke range corresponding to the full machine width divided by the number of pairs. 
     
     
         6 . A textile machine comprising at least one row of stitch-forming tools and having an apparatus according to  claim 1  for each row of tools. 
     
     
         7 . A method for loading yarns into at least one row of stitch-forming tools of a textile machine having a yarn loader having at least one pair of rotors rotatable about a common axis one above the other and each having at least one yarn guide the method comprising the steps of:
 rotating the rotors in opposite directions of rotation; and   engaging the yarn guides as driver elements with the yarn being to lay the yarn in a respective one of the directions by each rotor.   
     
     
         8 . The method according to  claim 7 , further comprising the step of:
 feeding the yarn laid in one direction by a feeding device to the tools.   
     
     
         9 . The method according to  claim 7 , further comprising the step of:
 laying the yarn laid in the directions by two respective retaining devices that are near reversal points of the yarn spaced apart by the full machine width and thereby supplying the yarn to the tools.   
     
     
         10 . The method according to any one of  claim 7  wherein the yarn is laid by one respective pair of a number of pairs, each with two rotors of the yarn loader, over a stroke range that corresponds to the full machine width divided by the number of pairs.
