Definitions

  • the invention relates to a blind sewing machine of the type specified in the preamble of claim 1.
  • the fabric flexor is axially displaceable in a sleeve against the action of a helical compression spring arranged in the sleeve, the pretensioning of which can be changed without influencing the position of the fabric flexor with respect to the sleeve.
  • the sleeve is oriented perpendicular to the needle plate arranged on the head of the blind sewing machine and in turn can be moved axially back and forth on the fabric support arm of the blind sewing machine by means of a drive shaft mounted in the fabric support arm, with which the sleeve is connected so that even the smallest distance can be changed, up to which the sleeve can approach the needle plate when the blind sewing machine is in operation.
  • the stop against which the fabric flexer bulges the sewing material inserted into the blind sewing machine is pivotably mounted on the needle plate on the side thereof facing away from the fabric flexor about an axis running transversely to the material feed direction and is adjustable by means of an adjusting screw engaging the stop and screwable into the stitch plate,
  • an adjusting screw engaging the stop and screwable into the stitch plate
  • blind sewing machines of this type are not readily suitable for the subsequent sewing of labels with an unevenly thick peripheral edge on finished items of clothing along the label edge. It is not guaranteed that when sewing on such a label the bow needle of the blind sewing machine always sticks exactly the same depth into the item of clothing, for example when sewing on a square label with two folded-over parallel edges along all four label edges both on the two single-layer label edges and on the two two-ply label edges. This but is necessary for the correct attachment of the label. If, for example, it is to be sewn onto the lining of the item of clothing, on the one hand the bow needle must not pierce the layer of fabric covered by the generally very thin lining and on the other hand it must not happen that the bow needle does not pierce the lining.
  • the invention has for its object to provide a blind sewing machine of the type specified in the preamble of claim 1, with which labels with a non-uniformly thick peripheral edge, in particular square labels with two folded parallel edges, subsequently to finished items of clothing along the peripheral label edge or all four Label edges can be sewn on perfectly.
  • the blind sewing machine shown in FIGS. 2 to 4 is used, for example, to subsequently attach a rectangular label 1 to the lining 2 of a jacket 3 in the region of the middle back seam 4 of the jacket outer material 5 along all four label edges 6, 7, 8 and 9 sew on with a seam 10 each.
  • the two longitudinal edges 7 and 9 of the label have one layer, the two transverse edges 6 and 8 have two layers, because the two cut edges 11 of the label 1 cut off from a tape have been folded over.
  • the sewn-on label 1 runs transversely to the back seam 4 of the outer shell material 5.
  • the blind sewing machine has a needle plate 12 and a curved needle 13, which swings back and forth above the needle plate 12 along an arc-shaped movement path in the direction of the arrows 14 and 15 when the blind sewing machine is in operation.
  • the needle plate 12 and the bow needle 13 are provided on the head of the blind sewing machine.
  • the blind sewing machine has a presser plate 17 which is loaded by a helical compression spring 16 on the throat plate 12 and a fabric flexor 18 which is oriented perpendicular to the throat plate 12 and moves back and forth in a straight line in the direction of the arrows 19 and 20 when the blind sewing machine is in Operation.
  • the presser plate 17 and the flexor 18 are provided at the free end of the support arm 21 of the blind sewing machine, on which the helical compression spring 16 of the presser plate 17 is supported and with which the support arm 21 projects under the head of the blind sewing machine.
  • the fabric flexor 18 is axially displaceable in a sleeve 24 axially displaceably in the fabric support arm 21 and connected by means of a link 22 to a drive shaft 23 rotatably mounted in the fabric support arm 21 against the action of a helical compression spring 25 and cooperates with a stop 26 on the throat plate 12.
  • the pretension of the helical compression spring 25 arranged in the sleeve 24 can be changed by means of an adjusting nut 29 which can be screwed onto the end of the shaft 28 of the fabric flexor 18 which is provided with an external thread and protrudes from the bottom 27 of the sleeve 24 and with which a locking nut 30 also interacts can be screwed onto the end of the shaft 28.
  • the stop 26 is L-shaped and has a first arm 31 and a second arm 32, which are perpendicular to each other.
  • the throat plate 12 is provided on the side facing away from the fabric flexor 18 with a projection 33, on which the stop 26 is pivotally mounted about an axis 34, so that its first arm 31 into a slot 35 of the stitch plate 12 and towards the fabric flexor 18 protrudes, while the second arm 32 of the stop 26 extends approximately parallel to the throat plate 12 in order to be supported by an adjusting screw 36 on the throat plate 12, which can be screwed into a threaded bore at the free end of the second arm 32.
  • the stop 26 is provided with a bolt 37 which is received in a corresponding bore 38 at the free end of the projection 33 and has a head 39 which overlaps the bore 38.
  • the throat plate 12 is also provided with a bridge 40 which bridges the slot 35 of the throat plate 12 which runs transversely to the pivot axis 34 of the stop 26 at the end facing away from the adjusting screw 36.
  • the free end of the fabric flexor 18 is conical across the slot 35 of the needle plate 12 and the first arm 31 of the stop 26 is provided with a groove 41 on the free end facing this fabric flexion tip, which is parallel to the Slot 35 extends and on the right in Fig. 2 from an oblique nose 42 of the first arm 31 which projects downward to the right.
  • the stop 26 has a guide bar 43 parallel to its second arm 32 on the right-hand side in FIG. 2, the distance of which from the lateral nose 42 of the first arm 31 can be changed, for which purpose the guide bar 43 is attached to the stop 26 by means of two screws 44 is attached, which each pass through an elongated hole 45 of the guide bar 43 running parallel to the first arm 31.
  • a fixing needle 46 is provided on the fabric support arm 21 of the blind sewing machine, which extends parallel to the fabric flexor 18 on the right-hand side in FIG. 3 and can be moved to the slot 35 of the needle plate 12 by means of a compressed air cylinder 47 .
  • the compressed air cylinder 47 displaces a carrier 48 with an arm 49 bent at right angles to the fabric flexor 18, on which the fixing needle 46 is arranged and which rests with its end face 50, which runs transversely to the fabric flexor 18, on a likewise flat side surface 51 of the fabric flexor 18, so that the fabric flexor 18 cannot rotate in the sleeve 24.
  • the jacket 3 and the label 1 are inserted into the blind sewing machine and at the end of each of the first three seams 10 are rotated by a right angle that the four label edges 6, 7, 8 and 9 successively on the stop 26 of the needle plate 12 on the in Fig. 2 run past the same on the right.
  • the jacket 3 and the label 1 are gradually advanced in the usual way in the direction of the arrow 52 (FIGS. 3 and 4), the resilient flexor 18 after each feed step by the jacket 3 by the in the the slot 35 extending in the direction of advance 52 bulges out the opening of the throat plate 12 and presses against the stop 26 thereof, namely into the groove 41 of the first arm 31 thereof, while the respective label edge 6 or 7 or 8 or 9 through the nose 42 of the first arm 31 of the stop 26 from the feed 2 of the jacket 3 is spread apart, which engages between the label edge 6 or 7 or 8 or 9 and the lining 2.
  • the presser plate 17 can also consist of two parts, which are arranged in FIG. 2 to the right or left of the flexor 18 and are each separately movable perpendicular to the throat plate 12.
  • the arching needle 13 which swings back and forth transversely to the feed direction 52, sticks after each feed step into the label edge 6 or 7 or 8 or 9, which is bent by the nose 42 of the stop 26 from the jacket 3 or its lining 2 and on the guide bar 43 of the stop 26 abuts, which is also arranged on the side of the stop 26 facing the curved needle 13 when it vibrates in the puncturing direction 14.
  • the arch needle 13 pierces the lining 2 of the jacket 3 at the apex of the bulge caused by the fabric flexor 18, in order to pierce the lining 2, as is particularly evident from FIG. 2 can be seen, and finally to swing back in the direction of arrow 15 according to FIG. 2.
  • the stop 26 of the throat plate 12 is adjusted by means of the adjusting screw 36 so that the curved needle 13 sticks securely into the lining 2 of the jacket 3, and only into the lining 2 and not also into the outer jacket 5.
  • the guide bar 43 of the stop 26 is set so that the desired distance 55 of each seam 10 results from the associated label edge 6 or 7 or 8 or 9 (Fig. 1).
  • the fixing needle 46 is used as an aid. If, for example, as shown in FIG. 4, when sewing the third edge 8 of the label 1 to the lining 2 of the jacket 3 as illustrated in FIG. 2, the last stitch 56 of the seam 10 in question has been completed and the jacket 3 and the label 1 have subsequently been advanced by one step in the direction of the arrow 52, namely during the oscillation of the curved needle 13 in the direction of the arrow 15 after leaving the label edge 8 and its subsequent oscillation in the direction of the arrow 14 in Fig. 2 to the position shown in FIG.
  • the blind sewing machine is stopped, the compressed air cylinder 47 is actuated to move the fixing needle 46 so that it at least in the jacket 3 or its outer fabric 5 and lining 2 the place of the last bow needle insertion 57, namely below the point where the bow needle 13 last pierced the label edge 8, and finally moved the presser plate 17 by means of a compressed air cylinder, not shown, away from the throat plate 12 to the jacket 3 and that Release label 1.
