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.
Claims13
A 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 end sides of the rollers is sealed by a first compression plate and a second compression plate,
- wherein
- the first compression plate and the second compression plate at the start of a process are, for a time, actively pressed onto the end sides of the rollers and upon reaching a bearing position are in each case held by a radially acting clamping force, wherein
- a compression actuator and a clamping actuator act on a supporting piston which bears on an end side of one of the compression plates.
A 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 a first compression plate and a second compression plate which for sealing the roller gap bear on end sides of the rollers, the first compression plate and the second compression plate both having a respective compression actuator for pressing on the compression plates,
- wherein
- the first compression plate and the second compression plate both additionally have a respective clamping actuator for clamping the compression plates, and in that at least one control apparatus for controlling both the compression actuators and the clamping actuators is provided,
- the at least one control apparatus is configured so that the compression plates at the start of a process are briefly actively pressed onto the end sides of the rollers and upon reaching a bearing position are in each case held by a radially acting clamping force, and
- one of the compression actuators is configured to act axially and one of the clamping actuators is configured to act radially on a respectively assigned supporting piston which bears on one of the compression plates.
