Abstract
A wire uncoiler for holding coils of wire on mandrels for uncoiling and drawing by a downstream wire drawing machine. The movable restraining arm of each mandrel is biased by a spring mechanism to control wire payoff to the downstream drawing machine. The spring mechanism can be manually adjusted by a crank handle to control the tension in the spring and therefore the amount of restraining force applied by the restraining arm. The manual adjustment can be done while the wire drawing machine is actively drawing wire from the mandrel.
