Abstract
Techniques are directed to operating a crimping apparatus, and to a crimping apparatus for crimping a fibre strand having at least two driven rollers and a stuffer box. A nip is formed between the rollers and is sealed off at the end faces of the rollers by press plates. The press plates at the start of the process are temporarily actively pressed against the end faces of the rollers by press actuators, and, once a contact position has been reached, are held in place by generation of a clamping force by clamping actuators. Each press plate, in addition to a press actuator, is thus also associated with a clamping actuator for clamping of the press plate, the press actuators and clamping actuators being controllable by at least one control unit.
