  • the tip 77 a of the movable foil 77 is elastically inserted into the hole 82 of one of the paillettes 80 of the strip 81 and, during the forward movement, thrusts forwards the strip 81 that feeds the paillettes 80 , making it slide on the bottom of the groove 78 and making it advance by a quantity more or less equal to the diameter of the paillettes 80 in use.
  • the first paillette 80 a of the strip 81 that has to be applied finds itself with its hole 82 in axis with the hole 73 in the toothed pulley 72 through which the needle passes.
  • a centering device is provided, consisting of a supporting pin 79 fixed to the protruding part of the PAILLETTES foot 70 .
  • a ring 85 rotates on the pin 79 , bearing a positioning hook 86 with the same diameter as the hole 82 of the paillettes 80 in use, a drive lever 90 and a return-action spiral spring 87 .
  • the tip 77 a of the feed foil 77 thanks to its shape, jumps elastically from the hole 82 of the previous paillette 80 to that of the following paillette on the strip 81 , without making it slide backwards because it is braked by a felt 88 which presses it against the bottom of the groove 78 , while a peg 89 mounted on the cursor 76 thrusts the drive lever 90 backwards, causing the positioning hook 86 to lift, the end of which, hook-shaped, exits from the hole of the paillette 82 in which it was inserted and also causes the spiral spring 87 to load.
  • the tip 77 a of the feed foil 77 enters into the hole 82 of a paillette 80 and thrusts the strip 81 forwards, making it slide on the bottom of the groove 78 , while the peg 89 gradually releases the drive lever 90 and consequently, due to the effect of the thrust of the spiral spring 87 , the pointed hook of the positioning hook 86 , is lowered and inserted into the hole 82 of the previous paillette 80 on the strip 81 , exactly centering the first paillette 80 with the axis of the relative sewing needle 14 .
  • a plane contrasting foil 91 suitably shaped, keeps the strip 81 pressed inside the groove 78 in the last segment between the positioning hook 86 and the toothed pulley 72 .
  • the feed movement of the strip 81 occurs during the descending movement of the sewing needle 14 , so that the needle 14 enters into the hole 82 of the paillette 80 to be applied (the first on the strip 81 ) at the moment when the paillette 80 is centered with the axis of the needle 14 by the positioning hook 86 .
  • a rotary blade 92 is provided, consisting of a hardened steel ring 93 inserted into the lower part of the hole 73 in the toothed pulley 72 where the needle passes.
  • the ring 93 has a protuberance in the part facing downwards which protrudes from the lower plane of the toothed pulley 72 ; the protuberance in turn has a small sharpened platelet 94 rotating in a circular groove which, during its rotation, comes into contact with the side of the strip 81 and is inserted into the throat between one paillette 80 and the next, cutting the first paillette 80 at the moment after that when the needle 14 has entered the hole 82 of the paillette 80 .
  • the bobbin that feeds the strip 81 is positioned above the paillettes foot 70 and is supported by an arm equipped with a pin on which the bobbin rotates, attached to the structure of the machine.
  • the feed foil 77 and the support of the rotation pin 79 of the positioning hook 86 are adjustable so as to allow the exact phasing thereof and to obtain the exact distance between the hole 82 of the paillette 80 in which the positioning hook 86 is inserted, and the first paillette 80 of the strip 81 that is to be applied.
  • the paillettes 80 can be applied on the fabric 11 in three different ways: sequential, superimposed and with star point, which have already been described in detail.
  • paillettes 80 Apart from the continuous application of paillettes 80 , both sequential, superimposed and with star point, it is also possible to alternate the application of paillettes with segments of normal stitching or embroidery type stitching, and thus create a very large number of ornamental patterns.
  • the PAILLETTES type robotized foot 70 is suitable to apply paillettes 80 of variable diameter, for example 3 mm, 5 mm, 7 mm, by making the necessary modifications and adjustments of the components.
  • the TRESSE′ type slider 51 is similar to the ECORDING type robotized foot 30 , since it is equipped with a toothed pulley 31 a substantially equal to that of the ECORDING type robotized feet 30 , provided with the same insert made of ceramic material, in this case indicated in its entirety by the reference number 32 a , provided with a central hole 61 for the needle 14 a.
  • the TRESSE′ type slider 51 is provided with a clamping device 52 able to selectively clamp the rotation of the toothed pulley 31 a so that, when the latter is clamped, the movement of the toothed belt 23 determines the movement of the TRESSE′ type slider 51 along the corresponding guide 50 , transverse to the fabric 11 .
  • a needle 14 a is mounted at every one of the ends of the needle-bearing bar 13 a , without the corresponding standard feet 28 , 28 a on the auxiliary supporting bar 19 , while on the needle-bearing bar 13 b a plurality of needles 14 are mounted, corresponding to the number of stitches to be performed, with the standard feet 28 mounted on the rear part of the auxiliary supporting bar 19 , in correspondence with the needles 14 .
  • the tape or ribbon or trimming 48 is fed from a bobbin, of a substantially conventional type and not shown in the drawings, and is made to pass in a corresponding hollow 62 made through on the insert 32 a of the toothed pulley 31 a.
  • the TRESSE′ type slider 51 substantially provides the following functioning cycle.
  • the TRESSE′ type slider 51 is stationary, for example at the right end of the auxiliary supporting bar 19 .
  • the toothed pulley 31 a is clamped by the clamping device 52 ( FIG. 10 ) in a position such that its central hole 61 is in axis with the needle 14 a mounted at the right end of the needle-bearing bar 13 a , and its hollow 62 through which the tape 48 passes is behind said needle 14 a with respect to the side on which the fabrics 11 are inserted.
  • the sewing machine 10 starts to sew, the fabrics 11 are fed forwards, all the needles 14 perform parallel stitches and the stitch of the needle 14 a mounted at the right end of the needle-bearing bar 13 a fixes the tape 48 to the fabric 11 .
  • the TRESSE′ type slider 51 acts as a fabric pressing element.
  • a third step of the cycle the needles 14 stop in a high position, the feed of the fabric 11 is stopped and the clamping device 52 releases the toothed pulley 31 a ( FIG. 11 ).
  • the command motor 26 of the toothed belt 23 performs a small rotation sufficient to make the toothed pulley 31 a rotate by 90°, so that the hollow through which the tape 48 passes moves to the left of the needle 14 a with respect to the side on which the fabrics are inserted.
  • the clamping device 52 clamps the toothed pulley 31 a in the position reached.
  • the command motor 26 moves the toothed belt 23 , which draws the TRESSE′ type slider 51 along the sliding guide 50 until it covers the whole width of the fabric 11 .
  • the tape 48 passes through the corresponding hollow 62 and is laid transverse on the fabric 11 .
  • the TRESSE′ type slider 51 reaches the left end of the auxiliary supporting bar 19 and the central hole 61 of its toothed pulley 31 a is in axis with the needle 14 a mounted at the left end of the needle-bearing bar 13 a.
  • the command motor 26 of the toothed belt 23 stops and the clamping device 52 releases the toothed pulley 31 a .
  • the command motor 26 performs a small rotation sufficient to make the toothed pulley 31 a rotate by 90° to take the hollow 62 behind the needle 14 a , with respect to the side on which the fabrics are inserted.
  • a sixth step is performed in which the sewing machine 10 starts sewing.
  • the fabrics 11 are made to advance and the needles 14 perform parallel stitches so that the needle 14 a fixes the tape 48 to the fabric 11 , while the stitches of the needles 14 mounted on the needle-bearing bar 13 b fix the tape 48 on the fabric 11 as it is laid transversely during the fourth step.
  • a subsequent seventh step of the cycle the needles 14 stop in a high position, the fabric 11 stops and the clamping device 52 releases the toothed pulley 31 a .
  • the command motor 26 of the toothed belt 23 performs a small rotation sufficient to make the toothed pulley 31 a rotate through 90°, so that the hollow 62 moves to the right of the needle 14 a , with respect to the side on which the fabrics 11 are inserted.
  • the clamping device 52 clamps the toothed pulley 31 a in the position reached.
  • the command motor 26 makes the toothed belt 23 move in order to draw the TRESSE′ type slider 51 along the sliding guide 50 until the central hole 61 of the pulley 31 a is in axis with the needle 14 a mounted at the left end of the needle-bearing bar 13 a .
  • This drawing of the TRESSE′ type slider 51 causes the tape 48 to be laid transversely for the whole width of the fabric 11 .
  • the movement of the toothed belt 23 can be supplied, instead of by the command motor 26 , by any suitable drive means, for example of a pneumatic, hydraulic, mechanical, electromagnetic or other type.
  • toothed belt 23 can be replaced by another transmission element, such as for example a chain, a rack or other.
