Wiredrawing Machines, Overhead Take-Off Type

An accumulation-type drawing system that has a succession of pulleys mounted on a framework above the machine. Wire passes from the die around a block, over an overhead pulley via a pulley on the waffle arm and on to the next die. A twist is thus imparted to the wire between each reduction. This difficulty is accentuated if for any reason one block of the machine has to be stopped for example when it is full. In this case all preceding blocks must also be stopped and where machines are equipped with an automatic control to stop full blocks this control also stops the preceding blocks. With double blocks only the full block need be stopped.
