A plant for making continuous yarns (30) made of silicon material comprises at least an extrusion station (12), into which the material is introduced in an amorphous condition, and extrusion means (15) which cause the material to exit from the extrusion station (12) along an extrusion axis (D). The plant also comprises a vulcanization station (16), located downstream of the extrusion station (12), at a determinate distance (“L”) therefrom, in which the continuous yarn (30) is vulcanized in a direction of treatment (T). The plant also comprises a drawing unit (18), disposed downstream of the vulcanization station (16).

The quench tube comprises a cylindrical wall through which quenching air flows when the quench tube is in use. The cylindrical wall comprises metal fibers in a nonwoven fiber structure. The metal fibers are bonded to each other at contacting points by means of metallurgical bonds thereby forming a three dimensionally bonded fiber structure.

A method and a device for producing a crimped multifilament thread are described. A multiplicity of filaments are extruded by means of a spinning machine, cooled and subsequently treated by a drawing device and a crimping device to form a crimped thread. Before the thread is wound up to form a bobbin, a multiplicity of intertwining knots is produced on the crimped thread by a treatment device. In order to obtain defined patterns of the intertwining knots within the thread, a pulse sequence of compressed air pulses at a predefined frequency is directed at the thread. The treatment device has a controllable blowing means.

The invention relates to a method and an apparatus for order control in a production process for a fiber product. In this case, at least one primary product is provided and processed further to form the fiber product, the processing steps of the further processing being performed by machines, the production process being monitored and controlled. According to the invention, in order to control and monitor a production order constituting the basis of the production process, an actual/target evaluation is performed between a target standard predefined by the production order and an actual status of the production process. The deviation from the target standard determined thereby is displayed.

An apparatus for producing and winding synthetic multifilament yarns, which has a spin unit 1 for melt spinning the yarns, at least one treatment unit 7 for treating the yarns, and a takeup unit 16 with a plurality of winding positions for winding the yarns. The winding positions 17.1-17.3 are distributed along a horizontal axis of the takeup unit 16, with a driven guide roll 12 and a yarn guide 15.1-15.3 for each winding position being arranged upstream thereof for advancing the yarn. To prevent different yarn deflections despite a different spacing between yarns while treating and while winding the yarns, the invention provides for orienting the guide roll 12 with its roll axis in the vertical direction to guide the yarns, and for arranging it laterally adjacent the yarn guides 15.1-15.3 such that the yarns can be advanced substantially in parallel relationship between the guide roll 12 and the yarn guides 15.1-15.3.
摘要:
A spinning-drawing-texturing machine for producing crimped threads is described, comprising a spinning device, a drawing device, a texturing device, and a take-up device. A plurality of threads spun by the spinning device is assigned to the drawing device, the texturing device, and the take-up device. According to the present invention, the drawing device and the texturing device are arranged in a processing module and the take-up device in a winding module underneath the spinning device. The processing module and the winding module are erected side by side and form one long side of the machine. This ensures a configuration divided by functional groups, which facilitates operation and increases operational reliability.
