Claims
- 1. A multi-system circular knitting machine having a needle cylinder provided with a plurality of needles, a plate ring provided with plates arranged for movement into and out of a working zone of the needles, and control cams cooperating with the plates for producing jacquard-patterned one-face plush webs of a main thread and at least two plush threads whereby each plush thread is inserted in a selected needle in separate system portions of a series of system portions in each system and subsequently knitted together with the main thread into the mesh, the machine comprising,
- separately controllable plates arranged in pairs with the number of pairs corresponding to the number of needles which are present in the needle cylinder, one plate in each pair being a loop sinking plate for processing the main thread, and the other plate being a knockover plate for processing the plush threads;
- the series of system portions of each system of the machine including a first and a last system portion;
- means for inserting the main thread in a needle and processing the main thread exclusively in the first system portion;
- the shape of the control cams being such that in the first system portion the knockover plates only are withdrawn from the working zone of the needles while in the last system portion both the knockover plates and the loop-sinking plates are withdrawn from the working zone.
- 2. A multi-system circular knitting machine as defined in claim 1, wherein the shape of the control cams is such that the knockover plates in at least one system portion between the first and the last system portions are shifted back relative to the loop sinking plates starting from a thread introducing position insertion region.
- 3. A method of producing jacquard-patterned one-face plush webs of a main thread and at least two plush threads in a multi-system circular knitting machine of the type having a needle cylinder provided with a plurality of needles, a plate ring provided with knockover plates and loop-sinking plates arranged for forward and backward movement into and out of a working zone of the needles, and control cams cooperating with the plates whereby each system in the machine is subdivided in a series of system portions having a first system portion and a last system portion, comprising the steps of driving the needles in said first system portion of each system for inserting therein exclusively the main thread, and simultaneously driving back the corresponding knockover plates from a thread introducing position, and subsequently driving down the needles to a position close to a knockover position and simultaneously sinking the loops of the main thread over the corresponding loop-sinking plate;
- displacing in a second system-portion of a system the knockover plates into a position in which the loop-sinking of the main thread is stopped while simultaneously driving up selected needles for inserting a first plush thread, and subsequently moving down the needles to a position close to the knockover position while loop-sinking the first plush thread over an adjacent plate;
- in said last system portion of each system driving up selected needles for receiving the second plush thread and subsequently driving down the needles while loop sinking the second plush thread over the corresponding knockover plate, and thereafter in the last system portion of each system driving back the loop-sinking plates and knockover plates, and then driving down the needles into their knockover position, and then driving forward the loop-sinking and knockover plates for post-tensioning of a formed plush loop.
