3 Claims. (C1. 66-121) This invention relates to circular knitting matype disclosed difficulty has been encountered in chines and more particularly to circular knitting insuring that the wrap or embroidery yarns w, machines arranged to knit a.`wrap or embroidery which are fed to the selected needles n1 by the yarn on selected ones of needles knitting a fabric wrap yarn finger 161, would maintain a position 5 of a single yarn or of a plurality of yarns in. on the selected needles when the body and facing 5 plating relation to form an embroiderypattern yarns b and f, respectively, are fed to the selected plated on the face of the fabric, and it is an obneedles by the yarn fingers F1 and F4, IGSDGC- ject of this invention to provide an improved tively, such that the wrap yarns would-.be found method of plating to insure .the desired yarn beon the face of the fabric'when the loops on thek ing on the outside of the fabric and it is a. furselected needles were cast oil' and knit as the l0 ther object of this invention to provide a needle wrap yarn w and the facing yarn j tended to be of improved construction for carrying out the imtransposed as to position and to bring the facing proved method of plating. yarn to the face of the fabric at the pattern in Inthe drawing in which only suchparts of a place 0f the Wrapping yarn.

In the operation of knitting machines of the shown in the drawin; as feeding the facing yarn 55 to the needles, and the displacement of the body and wrap yarns has occurred. Where the wrap yarn w is taken by alternate needles of a group to interlace the Wrap yarn with the needles of the group the movement of the wrap yarn into the notches 4 of the needles taking the yarn positions the wrap yarn further towards the back of the needles than formerly and renders the movement of the wrap yarn in back of the remaining needles of the group much easier and less liable to improperly position the wrap yarn with respect to other yarns taken by the Wrapped needles.

In the manufacture of the needle the notch is formed by applying a die under pressure to the needle blank before the hook is bentto shape so the needle is substantially of the same strength and cross-sectional areaI in the region of the notch as a needle without the notch and there is no tendency, either because of the shape of the notch or because of a reduction in the amount of metal at the notch, for the needle to break at the notch. Fig. 7 of the accompanying drawing illustrate the manner in which the notch is dieformed to provide substantially the same crosssectional area and strength at the notch as elsewhere in the hook portion of the needle.

In the claims wherever reference is made to a body yarn, it is intended such term shallalso include the facing yarn where the fabric is knit of a plurality of yarns in plating relation as well as the body yarn where the fabric is knit of Ibut a single yarn.

The method of plating described is not claimed herein as it is claimed in the divisional application Serial No. 206,048, led May 4, 1938.

What is claimed is:

1. A needle having a hook with the inner surface upwardly and outwardly inclined from the needle shank and a notch at the junction of said inner surface and shank to retain one yarn while another yarn is passed over the rst yarn to a position against said inner surface, said needle having substantially the same cross-sectional area and strength at the notch as elsewhere in the hook. .f

2. A latch needle having a yarn retaining notch at the junction of theinner faces of the shank and hook, said notch being arranged to retain a plating yarn to properly position said yarn with the remaining yarn in the knitted loop, said needle having substantially the same cross-sectional area and strength at the notch as elsewhere in the hook.

3. A needle having the inner face of the upper portion of the hook'a at surface inclinedto the axis of the needle shank and a notch at the junction of the inner face and shank to retain one yarn while a second yarn is passed over said first yarn to engage said at surface, the face of said notch merging into said inner face of the upper portion of the hook, said needle having substantially the same cross-sectional area and strength at the notch as elsewhere inthe hook.
