Circular knitting machine and method for knitting double-sided plush fabric with circular knitting machine

Abstract

A circular knitting machine used to weave a double-sided plush fabric. The circular knitting machine comprises a horizontal needle bed, a sinker bed and a vertical needle bed. The horizontal needle bed comprises a plurality of hook needles and a plurality of cutters spaced at intervals between the plurality of hook needles, the sinker bed comprises a plurality of sinkers, and the vertical needle bed comprises a plurality of knitting needles with cutters and a plurality of crochet needles spaced at intervals between the plurality of knitting needles with cutters. Before the knitting needles with cutters to be ready for cutting a first pile loop: a latch needle comprised in the plurality of knitting needle with cutters that is ready for cutting yarn comprises been completely cleared, and the plurality of knitting needle with cutters to be ready for cutting yarn passed through at least one plain stitch cam.

What is claimed is: 
     
         1 . A circular knitting machine comprising:
 a horizontal needle bed comprising a plurality of hook needles and a plurality of cutters spaced at intervals between the plurality of hook needles;   a sinker bed comprising a plurality of sinkers; and   a vertical needle bed comprising a plurality of knitting needles with cutters and a plurality of crochet needles spaced at intervals between the plurality of knitting needles with cutters;   wherein the circular knitting machine is configured to knit a double-sided plush fabric, the plurality of knitting needles with cutters are configured to form a basic structure and a first pile loop and a second pile loop connecting with the basic structure respectively with the plurality of hook needles and the plurality of crochet needles, the first pile loop and the second pile loop are respectively cut by the plurality of knitting needles with cutters and the plurality of cutters to form a plurality of plush structures respectively located on two opposite sides of the basic structure, before the plurality of knitting needles with cutters to be ready for cutting the first pile loop: a latch needle in the plurality of knitting needles with cutters to be ready for cutting yarn is completely cleaned, and the plurality of knitting needles with cutters to be ready for cutting yarn passed through at least one plain stitch cam.   
     
     
         2 . The circular knitting machine as claimed in  claim 1 , wherein each of the plurality of knitting needles with cutters is composed of a latch needle member and a cutter plate. 
     
     
         3 . The circular knitting machine as claimed in  claim 1 , wherein each of the plurality of knitting needles with cutters comprises the latch needle, and a blade with a horizontal height lower than that of the latch needle, and the latch needle is a head of each of the plurality of knitting needles with cutters. 
     
     
         4 . The circular knitting machine as claimed in  claim 3 , wherein the plurality of hook needles, the plurality of cutters, the plurality of sinkers, the plurality of knitting needles with cutters and the plurality of crochet needles are respectively guided to act by a plurality of cams. 
     
     
         5 . The circular knitting machine as claimed in  claim 1 , wherein the plurality of hook needles, the plurality of cutters, the plurality of sinkers, the plurality of knitting needles with cutters and the plurality of crochet needles are respectively guided to act by a plurality of cams. 
     
     
         6 . A method for knitting a double-sided plush fabric with a circular knitting machine, comprising:
 a first loop-forming procedure: feeding two yarns, and knitting a basic structure formed by one of the two yarns, and a first pile loop connected to the basic structure by at least one of a plurality of knitting needles with cutters and at least one of a plurality of crochet needles;   a second loop-forming procedure: feeding the two yarns, and knitting the basic structure formed by one of the two yarns, and a second pile loop connected to the basic structure by at least one of the plurality of knitting needles with cutters and at least one of a plurality of hook needles, the first pile loop and the second pile loop being located on two sides of the basic structure;   a first yarn-cutting procedure: controlling at least one of the plurality of knitting needles with cutters to cut the first pile loop to form a plush structure; and   a second yarn-cutting procedure: controlling one of a plurality of cutters to cut the second pile loop to form the other plush structure;   wherein the first loop-forming procedure does not follow by the first yarn-cutting procedure, when the plurality of knitting needles with cutters cut the first pile loop: a latch needle in the plurality of knitting needles with cutters to be ready for cutting yarn is completely cleaned, and the plurality of knitting needles with cutters to be ready for cutting yarn passed through at least one plain stitch cam.   
     
     
         7 . The method for knitting the double-sided plush fabric with the circular knitting machine as claimed in  claim 6 , wherein the method is achieved by sequentially performing the first loop-forming procedure, the second loop-forming procedure, the first yarn-cutting procedure and the second yarn-cutting procedure.
