Definitions

  • the subject of the invention is a machine, the role of which is to automatically pose and fix a junction tab used to join transversely the two parallel strips which constitute the slider closures.
  • Slider closures are used a lot in making clothes; we know that this kind of closure is presented as a ribbon composed of two parallel strips which have on two longitudinal edges close to each other stapling means that a slider allows to hang together or release.
  • closures are supplied by manufacturers in rolls of great length; intervals where the strips are devoid of attachment means separate the successive closings.
  • a transverse joining tab which securely joins the two parallel strips, below the hooking means when the closure is put in position of use.
  • This connecting tab makes the closure easier to handle, to set up and to sew on clothes. It also contributes to reinforcing the stop for the travel of the cursor which is provided on the stapling means.
  • the main object of the invention is to achieve a machine which sets up and sews connecting tabs on slider closures supplied in strips of very long length rolled up; this strip is rewound in a roll after sewing the junction tabs and the slider closures are separated from each other just when they are used.
  • a machine according to the invention ' comprises a means of unwinding a strip of rolls of slide fasteners, a means of rewinding this strip of slider closures, a sewing machine with presser foot having a low stitching position and a raised position, means for guiding in the longitudinal direction tolerating a limited movement in transverse direction under the presser foot of the strip of slider closures between the means and the rewinding means.
  • a means of continuous supply of tape to constitute the junction tabs is disposed above the strip of slider closures, guide means guide this tape between the cutting blades arranged transversely to the latter of a cutting member ; a clamp with two branches placed transversely to the same ribbon is mounted on a means for driving in translation of said clamp between a first position upstream of the cutting blades of the cutting member and a second position downstream of the presser foot at the level of the upper side of the slider closure strip.
  • the clamp is supported by a movable element in rotation with an amplitude of 180 ° in one direction and in the opposite direction.
  • This element comprises an actuator with alternating travel in a transverse direction to the ribbon so that the branches of the clamp can be moved between a first position in which they contain the ribbon and a second position in which they are recessed with respect to the same ribbon .
  • the element disposed in a direction transverse to the strip of slider closures is coupled to the piston rod of a jack by means of a slide provided with a rack; this element is provided with a toothed wheel meshing with the rack which imposes a rotation of 180 ° at the time of its displacement in translation.
  • the jack and the rack are arranged in a plane parallel to the strip of slider closures but with an inclination which corresponds to the path between the first position and the second position of the clamp relative to to said band.
  • a detector of the terminal end of each slider closure is placed in the path of the strip and the operation of the various components of the machine is controlled by this detector when the terminal end of a slider closure arrives to this detector.
  • the machine comprises, upstream of the presser foot, a holding means which serves to properly hold the junction tab deposited by the clamp on the strip of slider closures during the cutting of the ribbon by the '' cutter before stitching by the sewing machine.
  • the machine of the invention comprises a sewing machine 1, of any suitable type available commercially, which comprises a presser foot 2 movable under the effect of automatic internal members between a raised position where this foot is on Figure 1 and a low stitching position.
  • Each closure 5 has a terminal end 7 which precedes an interval 6.
  • the entire strip 4 is guided by guide means of which only two are shown and designated by the references 8 and 9 in FIG. 1. These guide means pass the strip 4 under the presser foot 2 and direct it up to 'to a means of winding 10 this strip on itself which therefore moves in the direction indicated by an arrow F while passing through the sewing machine 1.
  • the guide means 8 comprises a detector 8A at the end of each slider closure 5; when the latter have metal stapling elements, the detector is of the magnetic type. It is this detector 8A which controls the succession of operations which will be described later.
  • the guide means 9 it is advantageous for the guide means 9 to comprise an end of strip 4 detector, for example an optical detector, intended to stop the machine when the strip 4 comes to an end.
  • a ribbon supply means 11 is installed above the strip 4 of slider closures. This feeding means It provides a ribbon 12 which descends towards the sewing machine 1 and towards the upper face of the band 4.
  • a cutting member 13, comprising a fixed lower blade 14 and a movable upper lamp 15 connected to a jack 16 , is arranged upstream of the sewing machine 1.
  • the tape 12 passes between the cutting blades 14, 15.
  • This clamp 17 is carried by an element 19 movable in rotation which comprises a jack 20 of which one end of the piston rod is provided with the clamp 17 while the opposite end is provided with a toothed wheel 21 The latter meshes with a rack 22 which is part of a means 23 for translational driving of the element 19 and of the clamp 17.
  • This means 23 comprises a slide 24 which carries the rack 22 and which is connected to the piston rod of a jack 25.
  • the latter, the slide 24 and the rack 22 are arranged in a plane parallel to the strip 4 of the closures 5 but the slide 24 and the actuator 19 are guided in translation by slides 26, 27 respectively which are inclined.
  • the inclination is chosen so that the clamp 17 occupies a first position at which it is upstream of the cutting member 13 at the level of the tape 12 above the strip 4 and a second position at which the same clamp 17 is downstream of the presser foot 2 and rests on the upper face of the strip 4, or at least it is not far from this surface.
  • the jack 20, the piston rod of which carries the clamp 17, has a stroke which enables it to give the latter, in the transverse direction to the ribbon 12, a first position at which this ribbon 12 is contained between the branches 18, and a second position at which branches 18 are set back relative to this same ribbon 12.
  • a holding means 28 consisting of a jack arranged vertically and provided with a pad 29 capable of being applied against the strip 4, or more exactly as will be seen below, against the tape 12 resting on the strip 4 which itself rests on the plate of the sewing machine.
  • the machine of the invention operates as follows.
  • the strip 4 of successive slider closures 5 is wound by the winding means 10, which causes it to unwind from the unwinding means 3 passing in the direction F under the presser foot 2 and through the guide means 8, 9.
  • the detector 8A detects the terminal end of a slider closure 5, it causes the movement of the strip 4 to stop.
  • This detector is placed by relative to the presser foot 2 so that, when the strip 4 stops, the terminal end 7 is located just downstream of this same presser foot 2.
  • the ribbon 12 is supplied by the supply means 11; the clamp 17 is pushed by the jack 20 to its first position at which the ribbon 12 is taken between the branches 18 upstream of the cutting member 13 whose movable blade 15 is in the open position.
  • the jack 25 is actuated to push the slide 24.
  • the rack 22 rotates the toothed wheel 21 and, consequently, the clamp 17.
  • the length of the rack 22 is determined so that the toothed wheel 21 and the clamp 17 rotate only 180 °, after which the toothed wheel 21 is blocked by the end of the rack 22, the movable assembly 19 is driven in displacement above the strip 4 along an inclined path bringing it closer to it.
  • the 180 ° rotation of the clamp 17 has clockwise folded the end portion 12A of the strip 12 and the movement causes the branches 18 and the folded end portion 12A of the strip 12 to pass between the open cutting blades 14, 15 of the cutting member 13.
  • the movement continues until the clamp 17 arrives at its second position where the folded end portion 12A rests on the strip 4 just behind the terminal end 7 of a closure to cursor 5.
  • the pad 29 of the holding means 28 is applied against the tape 12 and it holds it on the strip 4.
  • the jack 20 pulls the clamp 17 to its second withdrawal position and the jack 25 retracts; the slider 24 returns to its initial position by carrying with it the clamp 17.
  • the jack 20 carrying the clamp 17 arrives at the end of its return stroke and the rack 22 rotates the toothed wheel 21 and consequently, the clamp 17 by 180 ° in a counterclockwise direction which returns the latter to its first position.
  • the jack 20 extends and the clamp 17 advances to again contain the ribbon 12.
  • the latter being taken in the clamp 17 upstream of the cutting member 13 and clamped under the pad 29 upstream of the presser foot 2, the jack 16 actuates the cutting blade 15
  • the ribbon 12 is cut. Its new free end portion remains retained in the clamp 17 upstream of the cutting member 13. Downstream of the latter, a long strand 12B extends to under the presser foot 2 covering the short strand 12A folded from below ; these two strands rest on the strip 4 of the slider closures.
  • the presser foot 2 is lowered at the same time as the pad 29 is raised.
  • the sewing machine 1 performs a transverse stitching 30 behind the fold which is located between the two strands 12A, 12B of the tape 12.
  • This machine is equipped, as is common, with the members necessary for movement in the direction of stitching of the strip 4 and of the tape 12 under the presser foot 2.
  • the means for guiding the strip 4 are designed to allow this transverse movement.
  • the two parallel strips of the slide fastener are joined by a connecting tab. The length thereof is determined by the distance between the cutting member 13 and the sewing machine 1.
  • the buffer 29 is not necessary; maintaining the tape 1 2 on the tape 4 can be ensured by the presser foot 2 the clamp 17 has fairly fine branches 18 or when the puncture can be made at a greater distance from the branches 18 of the clamp 17.
  • the detector 8A of the terminal end 7 of the slider closures can be deleted when the pitch of these ends 7, on the strip 4, has a constant value.
