Definitions

  • the present invention relates to a stitching head for a stitching or embroidery machine, intended in particular for making loop stitches and comprising, for its attachment to the machine, a support in which slides at least one needle associated with a main presser foot provided a pressing heel.
  • Textile items such as T-shirts or pullovers, decorated with decorative patterns made with terry stitch, are increasingly popular with the general public, and in particular by young people.
  • the present invention proposes to remedy these drawbacks and to do this, it relates to a stitching head for stitching or embroidery machine of the aforementioned type, which is characterized in that it comprises a foot auxiliary presser independent of the main presser foot and provided with a heel pierced with at least one opening, the auxiliary presser foot being slidably mounted relative to the support of the stitching head, along an axis parallel to the needle, and in such a way that its heel is disposed in the descending trajectory of the main presser foot, parallel and at a distance from the pressing heel of the latter, while having its opening situated in the path of a respective needle, return means being designed to permanently urge the auxiliary presser foot towards the main presser foot.
  • the auxiliary is driven by the main presser foot presser foot and is rap - peeled automatically to its rest position when it is raised. Consequently, if a thick wire is engaged in the opening of the heel of the auxiliary presser foot, this wire will form, during a back and forth movement of the main presser foot, a loop which can be fixed by a seam performed using the needle.
  • the stitching head according to the invention can be produced by a simple adaptation of a conventional stitching head. It can also, if the auxiliary presser foot is not provided with a thread, operate at the conventional stitching head, which considerably increases its profitability.
  • the auxiliary presser foot consists of an arm parallel to the needle, the lower end of this arm being bent in the direction of the latter and wearing the heel.
  • the auxiliary presser foot consists of two arms parallel to the needle and connected, at their lower end, by a flat cross member which constitutes the heel.
  • means are provided for adjusting the height in the rest position of the heel of the auxiliary presser foot.
  • these means consist of at least a first adjustable-stroke micro-cylinder mounted above a respective arm of the auxiliary presser foot, its rod being directed towards the corresponding arm parallel to 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 bring the heel of the presser foot auxiliary very close to the work platform 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 head as described above.
  • the first embodiment of the stitching head according to the invention comprises in known manner a needle holder 1 slidably mounted inside a sleeve 2 constituting a support for the attachment of the stitching head 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 called “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 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.
  • return means 14 are provided to urge the auxiliary presser foot 10 permanently towards the main presser foot 7.
  • These return means 14 are constituted by a helical spring 15 mounted in compression around of the arm 10a of the presser foot 10, between a flange 16 provided at the upper end of the latter and the sleeve 11.
  • a micro-jack 17 with adjustable stroke is mounted on the above the arm 10a of the auxiliary presser foot 10 so that its rod 18 is directed towards the rim 16 of the latter parallel to the arm 10a.
  • the rod 18 of the jack 17 serves as a limiting stop for the return stroke of the auxiliary presser foot 10.
  • a second micro-cylinder 19 with a longer stroke is mounted along the first, above the rim 16 of the auxiliary presser foot 10.
  • the rod 20 of this second micro-jack brings and maintains the heel 12 of the auxiliary presser foot 10 very close to the plate 5.
  • the two jacks 17 and 19 are fixed to the frame 3 of the machine or secured to the sleeves 2 and 11 (not shown).
  • the auxiliary presser foot 10 is driven downwards by the main presser foot 7 against the action of the spring 15, so that the thick thread 21 is kept pinched by forming, under the auxiliary presser foot 10, a loop.
  • the needle 4 is set in motion to make a stitching for fixing the loop using the thin wire 22. It should be mentioned here that, for reasons related to the density of the loops, this stitching is preferably carried out in thorn stitches.
  • This height can be reduced to a minimum if the piston rod 20 of the second micro-cylinder 19 mentioned above is placed in its maximum stroke.
  • the heel 12 of the auxiliary presser foot ⁇ is permanently in contact with the piece of fabric 23 and an embroidery in stitched threads of the "Kordel" type is obtained, instead of the loops.
  • the stitching head according to the invention can be used to make conventional sewing or embroidery stitches.
  • the piston rod 18 of the micro-jack 17 will be completely retracted to bring the auxiliary presser foot 10 into its maximum high position and thus free, below the latter, a passage sufficiently open for insertion of the part. tissue.
  • This arrangement can also be provided at each end of loop embroidery end.
  • the stitching head according to the invention can have many applications without requiring any adaptation or transformation. It can therefore be profitable as much as possible and this is what makes its great interest. Furthermore, it will be noted that the stitching head according to the invention can advantageously be produced by a very simple arrangement of a conventional stitching head.
  • FIG. 5 represents, seen from the front, a second embodiment of the stitching head according to the invention. It is actually a head with several needles 4, aligned or arranged in an arc, for making multi-color embroideries.
  • the stitching head comprises a support bar 24 in which the various needle holders 1 slide.
  • Its auxiliary presser foot 10 furthermore consists of two arms 25 parallel to the needles, arranged on either side other of these, and. connected at their lower end by a flat cross 26 forming a heel which fulfills the same function as the heel 12 of the first embodiment.
  • the crosspiece 26 is pierced with openings 27 equal in number to the needles 4.
  • the arms 25 of the auxiliary presser foot 10 are each associated with a compression spring 15, and with a first and a second micro-jack 17 and 19 identical to that of the first embodiment.
