  • Patent number: 3946924
    Abstract: A tube haul-off machine for extruded tubes comprising at least one pair of parallel spaced annular supporting wheels supported for rotation in opposite directions about a common axis. Each supporting wheel carries rotatable haul-off wheels which are arranged at a radial distance from the axis corresponding to the outer radius of the tube, and the axes of which are inclined relatively to the common axis. The haul-off wheels of one supporting wheel are inclined in the opposite direction of the haul-off wheels of the other supporting wheel. Upon rotation of the supporting wheels the haul-off wheels in engagement with the surface of the tube will travel along helices about said axis on the peripheral surface of the tube thereby to pull the tube along the axis.
