Abstract
Pour le déroulement et l'enroulement de bandes métalliques, on fait usage de broches extensibles (1) sur lesquelles est appliqué un revêtement (4) pour broche de bobineuse, afin d'éviter que les bandes métalliques (3) sensibles soient endommagées par les mâchoires dures (6) des broches. Comme lors de l'écartement des broches (1), dans la plupart des cas, la limite maximale d'élasticité du matériau élastomère constituant le revêtement est dépassée, entraînant ainsi des déformations permanentes, il arrive que le revêtement (4) s'élargisse et se détache malencontreusement de la broche (1) avec la bobine (3). Pour empêcher que le revêtement (4) soit sollicité au-delà de sa limite d'élasticité critique, on a prévu dans ledit revêtement (4) une entaille (5) s'étendant approximativement en forme de spirale d'une extrémité à l'autre de ce revêtement (4).For unwinding and winding metal strips, use is made of extendable spindles (1) on which is applied a coating (4) for the winder spindle, in order to prevent the sensitive metal strips (3) from being damaged by them. hard jaws (6) of the pins. As during the spacing of the pins (1), in most cases the maximum elastic limit of the elastomer material constituting the coating is exceeded, thus causing permanent deformations, the coating (4) sometimes widens and accidentally detaches from the spindle (1) with the coil (3). To prevent the coating (4) from being stressed beyond its critical yield strength, there is provided in said coating (4) a notch (5) extending approximately in a spiral shape from end to end. other of this coating (4).
