Abstract
A machine for scraping tire treads comprising two units (10, 30), one (10) upper and one (30) lower, arranged according to a vertical axis (y--y) for the handling and positioning of a tire (2) in a symmetrical position relative to a horizontal axis (z--z) and for operating the tire in rotation around an axis of rotation coinciding with the vertical axis of such handling and operating units (10, 30). There is further provided a unit (20) for work tools (21) placed in rotation around a vertical axis parallel to the axis of rotation of tire (2) and automatic means (5, 5a) for loading/unloading tire (2) on/from lower supporting and positioning unit (30).
Claims9
A machine for scraping treads of a tire, said machine comprising an upper and lower units rotatably mounted about a vertical axis of the machine for handling and positioning the tire in a horizontal position symmetrically relative to a horizontal axis, which intersects with the vertical axis, so that the tire is clamped by said two units and rotatable therewith about said vertical axis, a work tool unit mounted adjacent the tire and on the horizontal axis, and carrying thereon a pair of work tools which are disposed symmetrically with respect to said vertical and horizontal axes, and rotatable respectively about their own vertical axes parallel to the vertical axis of the machine, and means for automatically loading/unloading the tire on/from said lower unit.
