D'après le document EP-A-0070813 on connait déjà un dispositif automatique qui prélève le vêtement d'une machine qui coud les deux bas pour former le corps des collants destinés à recevoir un soufflet et le transfère à une machine qui coud les soufflets.According to document EP-A-0070813, an automatic device is already known which takes the garment from a machine which sews the two stockings to form the body of tights intended to receive a bellows and transfers it to a machine which sews the bellows. .

On sait aussi qu'avant la formation du collant ou après la couture de soufflet on doit effectuer la couture au bout des bas au moyen d'une ultérieure machine qui jusqu'à présent a été alimentée manuellement.It is also known that before the formation of the pantyhose or after the gusset stitching, the seam at the end of the stockings must be carried out by means of a subsequent machine which until now has been fed manually.

Le but principal de la présent invention est d'automatiser aussi l'opération d'alimentation d'une machine à coudre les bouts des bas et de permettre la couture successive du soufflet, avec un procédé complètement automatisé.The main object of the present invention is also to automate the operation of feeding a machine for sewing the ends of the stockings and to allow successive sewing of the bellows, with a completely automated process.

On est parvenu à ce résultat en conformité de la présente invention en adoptant l'idée qui consiste dans la couture des bouts d'un collant en le prélevant de la machine qui forme le collant et ainsi avant la couture du soufflet et en outre dans la préparation d'un déchargement du collant avec les bouts cousus de façon à utiliser un dispositif connu qui transfère le vêtement à une machine à coudre les soufflets.This result has been achieved in accordance with the present invention by adopting the idea which consists in sewing the ends of a pantyhose by removing it from the machine which forms the pantyhose and thus before sewing the bellows and also in the preparation of unloading the pantyhose with the ends sewn so as to use a known device which transfers the garment to a machine for sewing the bellows.

En conformité du procédé suivant l'invention on prévoit, en succession:

  • - de séparer les jambes du vêtement qui se trouve encore sur la machine de formation du corps, par aspiration dans deux cannes de renversement correspondantes de la machine pour coudre les bouts;
  • - de prélever le vêtement en élargissant la ceinture de son corps et le transférer sur une première section de la machine pour coudre les bouts en renversant le corps sur lesdites cannes;
  • - de renverser les jambes sur les dites cannes et de positionner les deux bouts du vêtement aux extrémités des cannes;
  • - de coudre lesdits deux bouts;
  • - de prélever le vêtement avec les bouts cousus en élargissant la ceinture de son corps, et le trans- ferer sur une deuxième section de la machine pour coudre les bouts en redressant les corps autour de deux cannes de support correspondantes dans lesquelles sont aspirées séparément les jambes du vêtement avec les bouts cousus;
  • - de raidir la zone périnéale ouverte du vêtement destinée au soufflet;
  • - de pratiquer par découpe une ouverture, si manquante, dans la zone périnéale raidie du vêtement;
  • - d'orienter le vêtement par rapport à un dispositif transporteur qui opère la prise du bord de ladite ouverture à travers cette ouverture.
In accordance with the process according to the invention, there is provided, in succession:
  • - to separate the legs of the garment which is still on the body forming machine, by suction in two corresponding reversing rods of the machine to sew the ends;
  • - take the garment by widening the belt of his body and transfer it to a first section of the machine to sew the ends by inverting the body on said rods;
  • - invert the legs on the said canes and position the two ends of the garment at the ends of the canes;
  • - to sew said two ends;
  • - take the garment with the ends sewn by widening the belt of his body, and transfer it to a second section of the machine to sew the ends by straightening the bodies around two corresponding support rods in which the legs of the garment with the ends sewn;
  • - to stiffen the open perineal area of the garment intended for the bellows;
  • - practice by cutting an opening, if missing, in the stiffened perineal area of the garment;
  • - Orient the garment with respect to a transport device which operates the grip of the edge of said opening through this opening.
