Circular knitting machine

Abstract

A circular knitting machine with a needle cylinder ( 11 ), in which cylinder needles ( 13 ) are mounted to be longitudinally displaceable, and a dial ( 12 ), in which rib dial needles ( 14 ) are mounted to be radially displaceable, wherein auxiliary elements ( 15 ), in particular sinkers, associated with the cylinder needles ( 13 ) and auxiliary elements ( 16 ), in particular sinkers, associated with the rib dial needles ( 14 ), as well as separate thread feeds to the cylinder needles ( 13 ) and to the rib dial needles ( 16 ) are provided, wherein separate tubular knits ( 19, 20 ) can be produced simultaneously or one after the other with the cylinder needles ( 13 ) and with the rib dial needles ( 14 ).

1 . A circular knitting machine, comprising:
 a needle cylinder in which cylinder needles are mounted to be longitudinally displaceable;   a dial upon which rib dial needles are mounted to be radially displaceable;   first auxiliary elements embodying sinkers, associated with the cylinder needles;   second auxiliary elements embodying sinkers, associated with the rib dial needles; and   separate thread feeds to the cylinder needles and to the rib dial needles;   wherein separate tubular knits can be produced simultaneously or one after the other with the cylinder needles and the rib dial needles.   
     
     
         2 . The circular knitting machine according to  claim 1 , wherein identical knits or knits in different fineness, can be respectively produced with the cylinder needles and with the rib dial needles. 
     
     
         3 . The circular knitting machine according to  claim 1 , wherein the tubular knits formed by the cylinder needles and the rib dial needles are removable jointly by a removal devise or by separate removal devices. 
     
     
         4 . The circular knitting machine according to  claim 3 , further comprising a removal device equipped with a spreader and with a cutting device on both sides. 
     
     
         5 . The circular knitting machine according to  claim 3 , further comprising a removal device with an open frame and a cutting device on one side. 
     
     
         6 . The circular knitting machine according to  claim 3 , further comprising a first removal device with an open frame and a second removal device without an open frame. 
     
     
         7 . The circular knitting machine according to  claim 3 , further comprising one, two or four folding devices for produced tubular knits. 
     
     
         8 . The circular knitting machine according to  claim 1 , wherein on a raising movement of the cylinder needles during stitch formation, the associated first auxiliary elements embodying sinkers perform a retraction movement and that on a withdrawing movement of the cylinder needles during stitch formation the associated first auxiliary elements perform a raising movement. 
     
     
         9 . The circular knitting machine according to  claim 1 , wherein on a raising movement of the rib dial needles during stitch formation the associated second auxiliary elements embodying sinkers perform a retraction movement and that on a retraction movement of the rib dial needles during stitch formation the associated second auxiliary elements perform a raising movement. 
     
     
         10 . The circular knitting machine according to  claim 1 , further comprising cylinder cam segments with needle cams for controlling the raising and withdrawing movement of the cylinder needles and sinker cams, with which the first auxiliary elements for the cylinder needles can be controlled to perform vertical movements, a swivelling movement or both around a horizontal axis. 
     
     
         11 . The circular knitting machine according to  claim 1 , further comprising dial cam segments, which have needle cams for controlling the raising and retraction movement of the rib dial needles and sinker cams, with which the second auxiliary elements for the rib dial needles, can be controlled to perform radial movements, a swivelling movement or both around a horizontal axis. 
     
     
         12 . The circular knitting machine according to  claim 1 , wherein the first and second auxiliary elements are mounted respectively in the needle cylinder and the dial or in separate devices. 
     
     
         13 . The circular knitting machine according to  claim 1 , wherein the first and second auxiliary elements are fixed knock-over bits. 
     
     
         14 . The circular knitting machine according to  claim 1 , wherein the cylinder needles, the rib dial needles or both are configured as bearded needles and the associated first and second auxiliary elements are configured as beard-closing elements. 
     
     
         15 . The circular knitting machine according to  claim 1 , wherein the dial is height-adjustable and the first and second auxiliary elements and the thread feed to the rib dial needles or the thread feed to the cylinder needles can be rendered inoperative, so that a fine rib tubular knit can be produced jointly with the cylinder needles and with the rib dial needles.
