Buncher versus Twinner
The main difference between a twinner and a buncher is that in most cases a twinner processes just two single wires or flexible cores that are supplied by motor-driven payoffs with a dancer control or a drag brake(s) and the take-up reel is the only means of setting the speed. Conversely, a buncher can have many wires from one or more reels or stem packs. The product speed is set by an internal capstan and the take-up reel is in torque mode.
