Abstract: A feeder for strip material has two carriage assemblies that reciprocate to move material intermittently through the feeder. The carriage assemblies are mounted on base plates that are adjustable relative to the center line of the feeder to accommodate different material widths. Each carriage assembly includes a clamp to grip the material. The clamp is moved between open and closed positions by an actuator that is orientated to transfer force directly between the clamping arms without transmitting clamping forces to the motor used to displace the actuator.
