| 摘要 |
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. |
