An embroidery device for crochet machines of the type having a looper arrangement and with a reciprocable needle bar for moving its needles into operative association with guide needles driven in an orbital pathway for loading warp threads carried thereby onto the needles of the needle bar. A plurality of bars driven in a rectangular pathway support tube elements through which weft threads are guided for linking them with the chains formed by warp threads. One of the rectangularly driven bars carries a plurality of guide tubes through which embroidery threads are guided. These guide tubes are also operatively connected to a supplementary vertical drive movement created by the pulling action of flexible members interconnecting the guide tubes with individual pulling elements. A pattern control unit is operatively connected to the pulling elements which are effective in causing the embroidery threads individual to each element to become linked within a chain so that it will not show on the fabric being formed or it is linked between two continuous chains when it is desired that it appear on the surface as part of a pre-selected design.
An embroidery device for forming designs on a base fabric with crochet machines having a plurality of needles mounted for movement toward and from warp thread guides for forming chains of warp threads and weft thread tubular guides mounted on a plurality of rectangularly driven bar members for feeding weft threads to the needles to be interlocked with the chains of warp threads, said embroidery device comprising:
