  • a row of hook needles 4 are arranged on a bar 2, which are parallel to one another and protrude forward.
  • the hook needles 4 can be grouped together in different groups.
  • the hook needles are moved back and forth in their longitudinal direction in a manner not shown.
  • the hook needles are guided in groove 6 of a knock-off bar 8.
  • a series of thread guides 10 are arranged, which are also held in a bar 12 which executes a reciprocating movement transversely to the direction of the thread guides 10, in each case by a supplied warp thread 14 on the associated hook needle 4 to insert.
  • two long-shot guides 18, 20 are also effective, each of which is fastened to rods 22, 24, which are each slidably mounted to and fro in a guide 26 of a swing arm 28.
  • the long weft guides 18, 20 each serve to insert a weft thread at least over part of the width of the knitted fabric in order to connect the individual knitted chains to one another.
  • thread layers 30 are still in use if are attached to a common rod 32, which is also slidably mounted in a guide 26 of the swing arm 28.
  • the thread layer 30 serves to act on a single thread along a knitted chain of the knitted fabric.
  • the swing arm 28 is pivoted back and forth about an axis 34 by means of a drive (not shown in more detail) in order to bring the longitudinal weft guides 18, 20 and the thread layer 30 into the respectively required position for removing the threads by the hook needles 4.
