Estimating the term…
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.
Method for operating a crimping device having two driven rollers by way of which a fibre strand is conveyed through a roller gap into a stuffer box and in which the roller gap at the end sides of the rollers is sealed by compression plates,
Crimping device for crimping a fibre strand, having at least two driven rollers which therebetween form a roller gap, having a stuffer box that is assigned to the roller gap, and having two compression plates which for sealing the roller gap bear on the end sides of the rollers and to which one compression actuator is in each case assigned for pressing the compression plates,
