Definitions

  • This invention is concerned with improvements in or relating to a heel rest arrangement for a pulling over and lasting machine, comprising a mounting for a heel-engaging member, which mounting, and thus the heel- engaging member therewith, is supported for movement in a direction extending heightwise of the bottom of a shoe to be operated upon and also in a direction extending lengthwise of such shoe bottom.
  • the heel rest arrangement will comprise a heel-engaging member, which may be pivotally mounted, for engaging the back seam region of the shoe, about a pivot supported on a mounting, the mounting being in turn supported for movement in the shoe-lengthwise direction in order to accommodate to different sizes of shoe last.
  • the back seam region thereof will be located at different locations heightwise of the shoe, the mounting for the heel-engaging member is itself mounted for heightwise movement thus to accommodate to shoes of different heel height.
  • the adjustment of the heightwise position of the heel-engaging member is at the discretion of the operator.

  • the provision of the indicator means which may be e.g. a visual display either on a screen or via a lamp or the like, dispenses with the need for the operator to exercise skill and experience in moving the mounting to its desired heightwise position, the operator now being required only so to move it until the visual display changes to indicate that a correct positioning has been achieved; where, therefore, a display on a screen is used, either the display may be changed or the display may be removed from the screen, while in the case of a lamp or the like the lamp need merely be switched off.

Abstract

Dans une machine de remise sur forme et de montage, on prévoit un agencement de support de talon (26) comprenant un dispositif détecteur de position (potentiomètre linéaire (52)) permettant de contrôler la position réelle de l'élément en contact avec le talon (bloc talon (32)), ainsi qu'un organe comparateur servant à comparer la valeur du signal de sortie du détecteur à une valeur prédéterminée, représentant la position désirée du bloc talon (32) dans le sens de la hauteur. Lorsqu'il se produit une différence entre ces deux valeurs, un affichage (30) peut indiquer la différence, afin qu'elle soit corrigée par l'opérateur, ou l'on peut utiliser un organe motorisé pour déplacer automatiquement le bloc talon (32) jusqu'à la position correcte. Dans une variante, on utilise également un organe de verrouillage qui est libéré dès qu'une différence se produit, ce qui permet à l'opérateur d'ajuster en hauteur la position du bloc talon (32), l'organe de verrouillage (50) reprenant automatiquement sa fonction. La commande est organisée de sorte qu'il soit impossible de commencer un cycle d'opérations tant qu'une différence est détectée.
