  • the pulling down of the stocking which has already been turned over is promoted by the fact that the upper straps 7, which rotate in the same direction as the lower straps 8 at the beginning of the cycle, are stopped during the pulling-off phase and thereby slightly brake the downward movement of the stocking.

Abstract

Un cycle de travail de l'appareil pour retourner les bas commence lorsqu'un bas (44), dont l'extrémité a été cousue sur une machine à mailler (41), est amené dans sa zone distributrice (40) où il est introduit, en étant centré, dans une griffe (26). Il est prévu à cet effet, une cellule photoélectrique (43) fournissant une impulsion pour le début du cycle, au moment où le bas a atteint la position exacte. De cette façon, le bas est saisi par la griffe (26) qui est poussée entre deux bandes (7) déplaçables séparément, au moyen d'un chariot (33) coulissant sur les éléments de guidage longitudinaux (34, 35), cependant que le bas (44) suspendu à la griffe (26) s'élève entre deux bandes sans fin (8), également entraînées, séparément, disposées sous les deux bandes supérieures précitées (7). L'extrémité inférieure du bas est suspendue au-dessous des deux bandes inférieures (8), dans un intervalle prévu entre deux peignes pouvant être écartés l'un de l'autre (46). Lorsque le chariot (33) atteint la position de fin de course précitée, il actionne un détecteur magnétique (38) par l'intermédiaire duquel les deux bandes inférieures (8) ainsi que les peignes (46) se ferment, cependant que la griffe (26) s'ouvre et est ramenée, par l'intermédiaire du chariot (33), en sa position initiale, dans la zone distributrice (40) de la machine à mailler (41). Le bas est maintenu par les bandes fermées (8). Par retour de la griffe (26), un autre détecteur magnétique (39) est actionné, lequel entraîne la fermeture des bandes supérieures (7) ainsi que le début de rotation des deux bandes (7, 8), ceci dans un sens tel que leurs brins se faisant directement face se déplacent vers le haut. De plus, une barre d'inversion (3) se déplace rapidement vers le bas, ce qui active une deuxième cellule photoélectrique (58) disposée entre les peignes (46) et les bandes inférieures (8). La barre d'inversion (3) est maintenue un court instant à la hauteur à laquelle se trouve la deuxième cellule photoélectrique (58). Dès que le bord libre de la partie de la jambe du bas retourné (44) n'obscurcit plus la cellule photoélectrique (58), les deux peignes (46) sont séparés l'un de l'autre par l'intermédiare de celle-ci, et les bandes supérieures (7) s'ouvrent avec un léger retard, cependant que la barre d'inversion (3) est de nouveau entraînée vers le haut, et que le sens de rotation des bandes inférieures (8) est inversé. Une fois que le bas retourné est retiré de la barre d'inversion (3), la cellule photoélectrique (58) est de nouveau libérée et agit de manière à maintenir les bandes inférieures (8), cependant qu'en même temps, les bandes des deux paires sont ouvertes, permettant ainsi le démarrage d'un nouveau cycle de retournement du bas suivant.
