Abstract

L'invention concerne un support de bobine comprenant un moyen de dégagement pour comprimer un élément poussoir, tout en exerçant une résistance à l'encontre d'un moyen de compression pour prendre une bobine et des moyens pour tirer le support en sens inverse du sens de poussée de l'élément de dégagement, au moment où un élément de retenue est désolidarisé. Comme une force de compression et une force de traction s'exercent simultanément sur le support, au moment où la bobine est dégagée, une force axiale s'exerçant sur le palier d'un arbre rotatif du support de bobine est annihilée, ce qui permet de protéger le palier d'éventuels endommagements ou de risques de diminution de sa durée de vie.
