Definitions
- the invention relates to a method for operating a crimping device according to the preamble of claim 1 and a crimping device for crimping a fiber strand according to the preamble of claim 6.
- Such crimping devices are used in particular in the production of staple fibers.
- the fibers of the fiber strand are crimped.
- the fibers of the fiber strand are passed through a nip which is formed between two driven rollers.
- the nip is followed by a so-called stuffer box, in which the fibers of the fiber strand are conveyed.
- the roll gap is sealed at the end faces of the rolls by a pressure plate in each case. It is customary to press the pressure plates against the end faces of the rollers with a pressing force.
- a crimping device in which the pressure plates are held on the end faces of the rollers by means of a pressure actuator and where a superimposed rotary drive leads to rotation of the pressure plates.
- a superimposed rotary drive leads to rotation of the pressure plates.
- wear is possible due to the pressure plates resting on the end faces of the rollers with a pressure load.
- the relative movements between the pressure plates and the end faces of the rolls to observe heat development, which leads to an increase in temperature of the adjacent fiber strands.
- the friction which is necessary for the wear and the heating, is also not significantly reduced by the rotation of the pressure plates, since the speed vectors of the pressure plates and the end faces of the rollers are not rectified.
- crimping devices are known in the prior art, in which a defined sealing gap is set between the end faces of the rollers and the pressure plate.
- DE 102 43 203 A1 discloses a crimping device in which the pressure plates are each arranged on the end plates of the rollers via a side plate with a predefined sealing gap.
- the sealing gap can be adjusted using a fixative.
- preset sealing gaps between a pressure plate and the end faces of the rollers generally have the disadvantage that individual filaments of the fiber strands are pressed into the sealing gaps. To this extent, wear between the pressure plates and the rollers is avoided, but with the after part that fibers are pressed from the nip into the sealing nip.
- the invention has the particular advantage that no pressing force acts between the pressure plates and the end faces of the rollers during operation of the crimping device.
- the pressure plates are immediately fixed in a position, in which there is almost no sealing gap, by clamping.
- the pressure plates are briefly pressed against the end faces of the rollers at the start of a process and are held in place by a clamping force after reaching a system position.
- the Kisseselvorrich device has a separate clamping actuator for clamping the printing plates, which can be controlled together with the pressure actuators by at least one control unit. After activating the clamping actuators, which fix the pressure plates in their respective system positions, the pressure actuators can be deactivated. In operation, there is no need to press the pressure plates against the end faces of the rollers.
- the pressure plates are clamped with a radially acting clamping force such that the pressure plates remain in the contact position during operation.
- the compressive forces generated in the interior of the nip by the water strand are to be absorbed by the clamping forces on the printing plates.
- the process variant is particularly advantageous in which each of the pressure plates is connected to a rotary drive and a superimposed rotation relative to the relevant end face of the rollers in the investment position. This will make the pressure on the pressure plate even reached.
- the crimping device has rotary drives which are coupled to the pressure plates, so that the pressure plates can rotate relative to the end faces of the rollers.
- the method variant is preferably carried out, in which the pressure plates are pressed axially against the end faces of the rollers with a pneumatically generated pressure force. No high forces are required, since the pressure forces occurring in operation in the nip are intercepted solely by the clamping forces acting on the pressure plates. The pressure force only serves to set the gap-free pressure plate position before the start of the process.
- the pressure plates are preferably held radially in the on position with a hydraulically generated clamping force. This ensures that the pressure plates remain in their contact positions during the operation of the crimping device.
- the sealing gaps that may form during operation are exclusively dependent on the material of the components and their modulus of elasticity. In extreme cases, these may only be a few micrometers.
- the setting of the pressure plates and the fixing of the pressure plates can preferably be achieved by means of a support piston which rests on one end face of one of the pressure plates.
- the forces for adjusting the pressure plates and for clamping the pressure plates can thus advantageously be generated directly on the support piston by the pressure actuator and the clamping actuator.
- the support pistons each have a rotatable shaft section, which are non-rotatably connected to the pressure plates and which are coupled to the rotary drives.
- the support pistons can be connected to the corrugated sections by a bearing, which enables the pressure forces to be transmitted.
- the crimping device according to the invention is particularly advantageous in a further development, in which one of the pressure actuators act axially and one of the clamping actuators radially on a support piston which rests on a pressure plate.
- the pressure actuator and the clamping actuator can thus advantageously be integrated into a structural unit which is assigned to the pressure plates with a support piston.
- the pressure actuator advantageously has a compressed air supply and the clamping actuator a hydraulic supply.
- the variant in which the pressure actuator and the clamping actuator are integrated in one housing is particularly compact.
- the unit can therefore also be operated advantageously in the harsh environment of a fiber line.
- the method according to the invention for operating a crimping device and the crimping device according to the invention thus offer the particular advantage that the fiber strands can be crimped and guided with great uniformity even in the edge area of the roll gap.

- Fig. 1 shows the embodiment in a front view
- Fig. 2 is a side view. Only the components of a crimping device that are essential to the invention are shown here.
- the crimping device has two driven rollers 1.1 and 1.2, which are arranged in a machine frame (not shown here) and are driven by at least one motor (also not shown here).
- the rollers 1.1 and 1.2 form a nip 2 between them.
- the rollers 1.1 and 1.2 are assigned a stuffer box 3 on an outlet side of the nip 2.
- the stuffer box 3 is delimited on both ends of the rollers 1.1 and 1.2 by a side plate 4.1 and 4.2, respectively.
- a side plate 4.1 and 4.2 Arranged between the side plates 4.1 and 4.2 is a base plate 3.1 and an upper plate 3.2, which between them the chamber inlet of the stuffer box 3 parallel to the wall form zen gap.
- the base plate 3.1 and the top plate 3.2 are directly assigned to the circumference of the rollers 1.1 and 1.2 on the inlet side of the compression chamber 3.
- the side plates 4.1 and 4.2 in the area of the nip 2 each have a pressure plate 5.1 and 5.2.
- the pressure plate 5.1 is left in the side plate 4.1 and is axially movable. Accordingly, the printing plate 5.2 is embedded in the side plate 4.2.
- the side plates 4.1 and 4.2 each have a recess 6.1 and 6.2.
- a support piston 7.1 and 7.2 is assigned to each of the pressure plates 5.1 and 5.2.
- the support pistons 7.1 and 7.2 penetrate through the side plates 4.1 and 4.2 and lie on the end faces of the pressure plates 5.1 and 5.2.
- a pressure actuator 8.1 and a clamping actuator 9.1 act on a projecting end of the support piston 7.1.
- the pressure actuator 8.1 and the clamping actuator 9.1 are connected to a control unit 11.
- a second pressure actuator 8.2 and a second clamping actuator 9.2 act on the free, projecting end of the support piston 7.2.
- the pressure actuator 8.2 and the clamping actuator 9.2 are also coupled to a control unit 11.
- the pressure actuators 8.1 and 8.2 and the clamping actuators 9.1 and 9.2 are only shown schematically in FIG. 1.
- electrical, pneumatic or hydraulic pressure actuators can be used, which testify an axially acting pressing force on the support pistons 7.1 and 7.2.
- the clamping actuators 9.1 and 9.2 could be formed by electrical, pneumatic or hydraulic clamping elements, which generate a radially acting clamping force on the circumference of the support pistons 7.1 and 7.2.
- the pressure plates 5.1 and 5.2 are initially moved synchronously axially by activation of the pressure actuators 8.1 and 8.2 by the control device 11 and guided with a pressing force on the end faces 10.1 and 10.2 of the rollers 1.1 and 1.2.
- the clamping actuators 9.1 and 9.2 are activated via the control unit 11, so that the support pistons 7.1 and 7.2 are fixed in their current position by a clamping force on the circumference.
- the pressure plates 5.1 and 5.2 are held by clamping in their contact position on the end faces 10.1 and 10.2 of the rollers 1.1 and 1.2.
- the pressure actuators 8.1 and 8.2 are deactivated, so that no contact forces act, and the pressure plates 5.1 and 5.2 remain in their contact position without contact pressure.
- fiber strands are now fed to the rollers 1.1 and 1.2.
- the fiber strands are drawn through the rollers 1.1 and 1.2 in the nip 2 and leads into the adjacent stuffer box 3 ge. This creates high operating pressures within the nip, which act against the pressure plates 5.1 and 5.2. To this extent, these compressive forces are caught by the clamping forces on the support pistons 7.1 and 7.2. There are no sealing gaps here.
- the pressure actuators 8.1 and 8.2 and the clamping actuators 9.1 and 9.2 can also be partially controlled by separate control devices which are shown in dashed lines in Fig. 1 and are identified by the reference numerals 11.1 and 11.2.
- the setting of the pressure plates 5.1 and 5.2 and the clamping of the pressure plates 5.1 and 5.2 on both end faces of the rollers 1.1 and 1.2 can thus be carried out independently of one another.
- the connection of the clamping actuators 9.1 and 9.2 and the pressure actuators 8.1 and 8.2 to the support pistons 7.1 and 7.2 is also exemplary. Depending on the design of the pressure actuators and clamping actuators, these could also act directly on the pressure plates and, for example, be partially integrated in the side plates.

- the pressure actuator 8.1 and the clamping actuator 9.1 are integrated in a housing 12.
- a support piston 7.1 is guided in a housing bore 20.
- the housing bore 20 is closed at one end and connected to a compressed air supply connection 13 formed on the housing 12.
- an air chamber 15 is formed within the housing bore 20.
- a return spring 18 is tensioned between the support piston 7.1 and the housing 12.

- the seals 19 limit the Ausspa tion 21 and act between the housing 12 and the support piston 7.1.
- a pressure chamber 16 is formed on the circumference of the clamping bush 17 and communicates with a hydraulic supply connection 14 in the housing 12.
- the support piston 7.1 has a projecting end which rests on a face of the pressure plate 5.1.
- the clamping actuator 9.1 is activated via the hydraulic supply connection 14. For this purpose, a hydraulic fluid is passed under high pressure into the pressure chamber 16, which leads to a clamping of the support piston 7.1 via the clamping bush 17. As soon as the support piston 7.1 through the clamping actuator

- the rotary drives 22.1 and 22.2 are activated via the control device 11 in order to rotate the pressure plates 5.1 and 5.2 relative to the end faces 10.1 and 10.2 of the rollers 1.1 and 1.2.
- each of the support pistons 7.1 and 7.2 has a shaft section 23.1 and 23.2 at the end facing the pressure plates 5.1 and 5.2, which is rotatably held on the support pistons 7.1 and 7.2.
