The present invention relates to a device for forming a loop or pile on the surface of the fabric, and more particularly to a device capable of forming a loop or pile stretch in the embroidery machine, but selectively forming a loop or pile on the surface of the embroidery fabric.

Embroidery generally refers to embroidering with needles, threads and other simple tools. Western embroidery and oriental embroidery are the types. Western embroidery includes French embroidery, Swedish embroidery, tulle embroidery, and cord. Embroidery, Ribbon Embroidery, Beads Embroidery, Spangle Embroidery, Cut Work Embroidery, Drawn Work Embroidery, Quilting Embroidery, Marvel Embroidery, Latch Hook latch hook embroidery, smoking embroidery embroidery, and so on.

Examples of pile fabrics include velvet, towel fabrics, carpet fabrics, and the like. There are various methods for producing the pile fabrics, but methods for cutting and forming woven fabrics tricot-laceled have been proposed. However, since the formation of the pile or loop on the surface of the embroidery fabric according to the present invention is to form only a portion of the fabric for decoration, it is obvious that there is a difference from the manner of implementing the structure of the fabric such as the double weave.

Regarding a device for generating a loop or pile stitch in the related art, Korean Patent Laid-Open Publication No. 96-14459 discloses a large, small tension bar (3,4), tension roller (2) and a large shaft to embroider embroidery.
