<p>Device for machining indentations in headrest tubes, comprising a support matrix that holds a tube in order to make indentations in it, positioned on a press that exerts a pressure on said matrix in a vertical direction such that the tube is rigidly secure in the support matrix. In addition, the device has a roller holder in which can turn freely at least one form roller, connected by an arm to a vertical displacement mechanism formed by a motor, an eccentric piece and a connecting rod, such that the roller can move up and down. In addition, a motor is coupled through a spindle to the assembly formed by the support matrix and the press, allowing it to move horizontally.</p> |
