Detailed Description
The present invention will be described in further detail below by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not to be construed as limiting the present invention.
Examples are given.
See fig. 1-4.
The embodiment discloses an inserting sheet for a single-groove double-needle-bar device, which is used for being inserted into an inserting sheet groove on a needle bar, a needle groove is formed between every two adjacent inserting sheets, two knitting needle groups are placed in the needle groove, and two knitting needles in the two knitting needle groups are arranged in an installation mode that widening sheets are back to back, as shown in fig. 1.
