Definitions

  • the invention relates to a device for upsetting a synthetic multifilament thread according to the preamble of claim 1.
  • a generic device is known from DE 4224454 AI.
  • the known device has a texturing device for producing a thread plug.
  • a multifilament thread is conveyed in the texturing device by means of a fluid stream and upset to a thread plug within a stuffer box.
  • the filaments of the thread are deposited in the form of loops and arches.
  • the thread is heated in order to obtain a high impression of the loops and arches within the filaments.
  • a cooling device is provided at a fixed distance below the texturing device, by means of which the thread plug is cooled. As a result, the loops and arches of the filaments are fixed within the thread plug, which leads to crimp resistance.
  • the transition of the thread plug from the texturing device to the rest device thus represents a phase in which the heat contained in the thread plug acts on the polymer of the thread.
  • the transition from the texturing device to the cooling device thus forms a warm section in which heat is neither supplied nor removed from the outside. In the known device, the length of the warm section is fixed.
  • the invention is characterized in that the length of the hot section, the. is formed between a plug outlet of the texturing device and a plug receptacle of the cooling device, is variable.
  • the length of the hot section is variable.
  • an adjusting means is provided, by means of which the distance between the stopper outlet of the texturing device and the stopper holder of the cooling device can be adjusted.
  • a very short warm stretch or a long warm stretch for thermal treatment of the thread plug can thus be predetermined, regardless of the speed of the thread plug.
  • the adjusting means for changing the distance between the texturing device and the cooling device can interact with a height-adjustable texturing device or with a height-adjustable cooling device.
  • the texturing device is designed to be height-adjustable, the position of the plug outlet of the texturing device is changed by the adjusting means relative to the plug holder of the cooling device.
  • the adjusting means acts in such a way that the position of the plug holder of the cooling device can be changed relative to the position of the plug outlet of the texturing device.
  • electrical, electromechanical or electrohydraulic devices are suitable as adjusting means.
  • the cooling device is formed by a cooling drum which has at least one plug groove which forms the plug receptacle and is circumferentially arranged on the circumference of the cooling drum.
  • the cooling drum is driven at a peripheral speed, which is essentially adapted to the speed of the thread plug to ensure a uniform plug formation within the texturing device.
  • the plug outlet is preferably formed by a discharge tube.
  • a minimum spacing is preferably maintained between the end of the inquiry tube and the plug groove of the cooling drum, so that a trouble-free transition of the thread plug from the texturing device into the cooling device is possible.
  • the discharge pipe of the texturing device is preferably oriented essentially perpendicular to the plug groove of the cooling drum. This results in a strong deflection of the thread plug, which enables the plug to be broken open and thus better cooled on the cooling drum. However, it is possible that the discharge pipe is aligned substantially tangent to the plug groove. There is no significant deflection of the thread plug.
  • the particularly advantageous development of the invention according to claim 7 is characterized in that not only the distance between the stopper outlet and the stopper but also the degree of deflection of the thread stopper is adjustable.
  • the impact position of the thread plug is changed relative to the circumference of the cooling drum by the interaction of the adjusting means with a texturing device that can be displaced relative to the cooling drum or with a cooling drum that can be displaced relative to the texturing device.
  • a short distance between the stopper outlet and the stopper holder is associated with a strong deflection of the thread stopper and vice versa a large distance is linked with a small deflection.
  • the impact position of the thread stopper is advantageously determined by the degree of deflection, so that the choice of a deflection angle can simultaneously determine the point of impact of the thread stopper.
  • the deflection angle can be set in a range between 0 ° and 90 °.
  • a combination between a height-adjustable texturing device and a displaceable cooling drum or vice versa represents a particularly preferred development of the invention.
  • a small deflection of the thread plug can be combined with a short distance, that is, a short warm section.
  • a very slow-acting cooling of the thread plug is achieved.
  • a long warm section can also be combined with a strong deflection of the thread plug.
  • the texturing device preferably has a nozzle-shaped conveying channel and a stuffer box, the thread being guided through a conveying fluid within the conveying channel of the texturing nozzle and opening into the stuffer box.
  • the thread is conveyed by means of conveyor rollers and guided into a stuffer box.
  • the height-adjustable cooling device can be guided into a contact position.
  • the texturing device for applying a thread and for starting the process is thus freely accessible.
  • the cooling device is then returned to an operating position in which a warm section predetermined for the respective process is set.
  • the device according to the invention is particularly suitable for crimping freshly spun synthetic multifilament threads made of polyamide, polyester or polypropylene.
  • the individually adjustable warm stretch enables optimal texturing with very high curling resistance for every type of polymer and every yarn that can be produced. However, it is also possible to immediately curl a thread drawn from a supply spool by means of the device according to the invention.

Abstract

L'invention concerne un dispositif de frisage par compression d'un fil multifilament synthétique, dans lequel ce fil est compressé à l'aide d'un système de texturation, jusqu'à l'obtention d'un enchevêtrement de fil. Cet enchevêtrement de fil est ensuite refroidi à l'aide d'un système de refroidissement puis démêlé jusqu'à l'obtention d'un fil frisé. Dans la zone de transition entre ce système de texturation et ce système de refroidissement, l'enchevêtrement de fil parcourt une ligne de chauffe, sensiblement définie par la distance entre une sortie d'enchevêtrement du système de texturation et une partie réception d'enchevêtrement du système de refroidissement. Selon cette invention, un moyen de réglage permet de régler la distance entre cette sortie d'enchevêtrement et la partie réception d'enchevêtrement.
