Title (EN) APPARATUS FOR THE AUTOMATIC CUTTING OF ELEMENTS MADE OF ELASTOMERIC MATERIAL
(FR) APPAREIL POUR COUPER AUTOMATIQUEMENT DES ELEMENTS EN ELASTOMERE
Abstract: front page image
(EN)The present invention relates to an apparatus for the automatic cutting of an element (50) made of elastomeric material, comprising: a rotary blade (11) having a continuous and curvilinear cutting profile, at least one cooling unit for cooling (16) said blade, a supporting structure (12) for supporting said blade, a feed device (14) for moving said supporting structure transversely relative to said element, a motor unit (15) for spinning said blade, and at least one structure (51) for supporting and feeding said element (50) to said blade. In accordance with the present invention, the ratio of the speed of rotation of said blade to the traversing speed of said feed device is between 10 and 40. Furthermore, said cooling unit (10) conveys cold air at least onto a radially outer portion of said blade, and at least one cutting surface on said blade, interacting, during the cut, with said element (50) of elastomeric material has non-stick properties.
(FR)L"invention concerne un appareil pour couper automatiquement un élément (50) en élastomère, comprenant: une lame circulaire (11) dont le profilé coupant est continu et curviligne ; au moins une unité de refroidissement pour refroidir (16) cette lame ; une structure support (12) pour recevoir la lame ; un dispositif de chargement (14) pour déplacer ladite structure support transversalement par rapport à l"élément ; une unité moteur (15) pour faire tourner la lame ; et au moins une structure (51) pour recevoir et charger ledit élément (50) relativement à la lame. Selon l"invention, le rapport entre la vitesse de rotation de la lame et la vitesse de déplacement du dispositif de chargement se situe entre 10 et 40. En outre, l"unité de refroidissement (10) amène de l"air froid au moins sur une partie radiale extérieure de la lame. De plus, au moins un plan de coupe de la lame, interagissant, durant la coupe, avec ledit élément (50) en élastomère, a des propriétés anti-adhérentes.
