Wiredrawing Machines, Cone Type
Wiredrawing machines that typically consist of two to three pairs of shafts with assemblies of three or more capstans of decreasing diameters mounted on each shaft. The dies are mounted between the two cones of the pair and are configured so that the speed of the drawn wire is less than the speed of the capstan. These slip-type machines are designed so that the wire can slip on the capstans. In most machines, the shafts are configured in pairs such that only the leading cone assembly in each pair does the pulling. The other assembly in each pair rotates at the same speed as the pulling assembly and serves to align the wire for entry into the die, Note: in some cone type machines, both assemblies draw the wire, doubling the number of available dies. The capstans on each shaft are sized to match the increase in wire speed as the wire passes through each die. See Wiredrawing Machines, Slip Type.
