  • the auxiliary embroidery member is constituted by an auxiliary presser foot independent of the main presser foot and comprising a pressing heel which is pierced with the opening in which the embroidery thread can be engaged with a possibility of sliding and which is placed on the path of the main presser foot, between the latter and the work plate, return means being provided to permanently urge the auxiliary presser foot towards the main presser foot, in a direction parallel to the movement of the latter, so that in operation, during said forward presser foot stroke, the auxiliary presser foot is moved away from the work plate by said return means by drawing up the embroidery thread on said given height, while during said return stroke next to the main presser foot, this pushes the auxiliary presser foot towards the work plate, the embroidery thread being then wedged between two s urges to pinch opposite the heels of the two presser feet to be folded back on itself.
  • the stitching device can produce loop stitches continuously and at a high rate.
  • this stitching device can advantageously be produced by a simple adaptation of a conventional stitching device on which it suffices to mount the auxiliary presser foot and its accessory elements.
  • the stitching device according to the invention can, if the auxiliary presser foot is not provided with an embroidery thread, function as a conventional stitching device for the production of sewing stitches, which considerably increases its profitability. .
  • the auxiliary presser foot consists of an arm parallel to the needle and the lower end of which is bent in the direction of the latter to form the pressing heel.
  • the auxiliary presser foot consists of two arms parallel to the stitching needles and connected at their lower end by a flat crosspiece which constitutes the pressing heel, this crosspiece being pierced with several openings, disposed respectively on the paths of the needles.
  • This second embodiment of the invention makes it possible to produce embroidery in multicolored loop stitches.
  • the return means will preferably be constituted by a helical spring surrounding each arm between a fixed sleeve in which the respective arm slides and a rim formed on the upper end of the latter.
  • means are provided for adjusting the height in the rest position of the heel of the auxiliary presser foot.
  • these means are constituted by at least a first adjustable stroke microvainer mounted above a respective arm of the auxiliary presser foot, its rod being movable towards said arm to come into contact with the latter. It will be understood that these means serve to regulate the height which it is desired to give to the loops to be produced.
  • a second micro-jack is mounted above each arm of the auxiliary presser foot, the maximum stroke of its rod being such that, when the stitching head is mounted on the machine, it can hold the heel of the presser foot auxiliary in contact with the piece of fabric resting on the work table of the latter.
  • This second micro-jack makes it possible to permanently maintain the auxiliary presser foot in contact with the piece of fabric to be embroidered, which enables stitching to be made.
  • the present invention also relates to a stitching or embroidery machine equipped with a stitching device as described above.
  • the first embodiment of the stitching device according to the invention comprises in a manner known per se a needle holder 1 slidably mounted inside a sleeve 2 constituting a support for fixing the device stitching on the frame 3 of a not shown stitching machine.
  • the needle holder 1 carries a needle 4 which extends perpendicular to the work plate 5 of the stitching machine as well as a presser foot 7, hereinafter referred to as "main presser foot", mounted in a well-known manner on the holder. needle 1.
  • the main presser foot carries at its free end a pressing heel 8 pierced with an opening 9 (see FIG. 2) disposed in the path of movement of the needle 4.
  • the means for moving the needle holder 1 and the main presser foot 7, means which are of known type, have not been shown in the figures.
  • the stitching device object of the invention comprises an auxiliary presser foot 10.
  • the latter is, independently of the main presser foot 7, slidably mounted along an axis parallel to the needle 4, to the inside a second sleeve 11 integral with the sleeve 2 of the needle holder 1.
  • the auxiliary presser foot 10 consists of an arm 10a parallel to the needle 4 and the lower end of which is bent in the direction of the latter , carries a heel 12 pierced with an opening 13 of small diameter (see FIG. 2).
  • the mounting of the auxiliary presser foot 10 relative to the main presser foot 7 is such that its heel 12 is disposed on the downward path of the main presser foot 7, parallel and at a distance from the presser heel 8 of the latter, while having its opening 13 located on the path of the needle 4. Once the stitching head mounted on the machine, the heel 12 is located between the work plate 5 of the latter and the pressing heel 8 of the main presser foot 7.
