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.

A method for producing at least one crimped multifilament synthetic yarn through the use of a texturing process, wherein a stream of heated gaseous medium is brought into a texturing channel (1), (2), (3), wherein synthetic filaments (4), (5), (6) are displaced and deformed by the heated gaseous medium in the texturing channel (1), (2), (3), wherein both the temperature and the flow rate of the gaseous medium are measured, and wherein the heat flow is regulated. To this end, the device comprises a regulating device (50) and, for each texturing channel (1), (2), (3), at least one temperature sensor (60), (61), (62) and a flow sensor (57), (58), (59).

A tow band for electronic cigarette tip is a tow band of cellulose acetate provided by uniting and crimping a plurality of filaments into a bundle, in which a total denier is set to a value in a range of 10000 to 40000 (inclusive) and a filament denier is set to a value in a range of 6.0 to 20.0 (inclusive), and where the total denier is denoted by TD and a breaking strength of the tow band is denoted by F, a ratio F/TD is set to a value of 0.0015N/denier or more.

Techniques produce a crimped composite thread, in which multiple individual threads are extruded in each case in the form of a plurality of strand-shaped filaments, cooled, drawn by means of a drawing device and together crimped by means of a crimping device to form the composite thread. Before the multifilament individual threads are crimped, they are entangled separately in each case by means of an entangling unit of an entangling device. A position and/or orientation of at least one of the entangling units relative to the drawing device, the crimping device and/or a further one of the entangling units is changed during the production of the crimped composite thread.

A textile stuffer box comprises a housing assembly having a yarn entrance and a yarn exit, and cooperating interior chamber-forming surfaces. The chamber-forming surfaces defines a multi-stage internal crimping chamber for receiving and accumulating a moving length of ply-twisted yarn between the entrance and exit of the housing assembly. The crimping chamber comprising an upstream fixed-volume stage and a downstream adjustable-volume stage. A weight-balanced gate selectively adjusts a volume of the downstream adjustable-volume stage of the crimping chamber, thereby controlling axial compression of yarn accumulating inside the upstream fixed-volume stage of the crimping chamber.

A system and method for controlling and improving the consistency of yarn texture in a yarn system. The system and method are configured to monitor, improve and/or control the operating parameters of the yarn system. A plurality of sensors sense the operating conditions and send the sensed conditions to a processor. The processor and/or a user monitoring the system can make adjustments to the operating parameters in a parameter is outside of a predetermined tolerance.
