    • The invention is a method and apparatus, and resultant product, for altering the form of material comprising the steps of synchronously driving a plurality of forming wheels, the forming wheels grooved to a radial depth of predetermined amount; spatially aligning the driven wheels in predetermined relationship; and feeding the material to be further formed successively to each of the forming wheels. The radial depth is sufficient to fully entrap the material. The shape of the groove conforms to the shape of the material with minimum clearance to prevent binding and yet to permit exertion of forming forces on the material.
    • 本发明是一种用于改变材料形式的方法和装置,并且得到的产品包括以下步骤:同步驱动多个成形轮,成形轮开槽至预定量的径向深度; 以预定关系空间对准所述从动轮; 并将要进一步形成的材料依次送入每个成形轮。 径向深度足以完全捕获材料。 槽的形状符合具有最小间隙的材料的形状,以防止结合并且允许在材料上施加成形力。
