Abstract
Continuous, elongated material is fed lengthwise in steps by clamping devices of which one is stationary on supporting structure, the other is reciprocated. Each device includes clamping jaws backed by a fluid-operated jack and return springs in such a manner that the stationary jack is spring-biased toward the clamping position, and the reciprocating jack is spring-biased toward the material-releasing position, both jacks being operated intermittently, against the restraint of the return springs by the simultaneously supplied pressure fluid. The return spring in the reciprocating jack is weaker than that in the stationary jack. The springs may be replaced by equivalent pneumatic devices.
