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.

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.

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.

Various techniques involve a device for entangling a plurality of individual threads of a composite thread in a melt-spinning process for the production of crimped yarns. The device to this end has a plurality of entanglement nozzles which are collectively held on a support. In order to enable a flexible utilization of the entanglement nozzles and of thread guiding, the entanglement nozzles on the support are assigned at least one thread guide in such a manner that the threads are guidable optionally in the entanglement nozzles and/or in the thread guide.

Additives such as colourants may be incorporated into polymeric materials such as polyesters, such as in polyester fibre production, by use of a liquid formulation comprising colourant and a vehicle. The vehicle may comprise a functionalised pentaerythritol, trimethylolpropane or trimellitate. The liquid formulation is suitably contacted with the polymeric material in a melt processing apparatus.

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 device for the production of strand-shaped products such as synthetic bands, fiber strands, monofilaments, or films, which are extruded from a polymer melt. The device includes an extrusion device, a cooling device, several rolling feed units and several processing devices mounted between the rolling feed units. In order to obtain short control paths and compact machine units, the processing devices according to the invention are arranged in tiers one above the other, wherein the rolling feed units face each other at both ends of the processing devices so that the product passes through the processing devices in the opposite direction.
摘要:
A melt spinning device produces a plurality of multi-filament threads which includes a spinning apparatus, a cooling apparatus, a drawing apparatus and a winding apparatus. The drawing apparatus has a plurality of godet units entwined by threads, each of said units having a plurality of godets, which are axially rectified to a coil spindle of the winding device. The transition of the threads as yarn from the drawing device to the winding device is executed by a guide godet which is aligned axially crosswise to the godets of the godet units and under the drawing device, so that the threads can be guided by simple partial wrapping after rotation of the thread running plane of the yarn by 90°.

Disclosed herein is a field emission device which makes it possible to reliably mass-produce nanofibers having satisfactory quality, even if field emission is conducted in such a way that high voltage is applied to a collector while a nozzle block is grounded. The field emission device includes a collector (150), a nozzle block (110) and a power supply (160) which has a positive electrode connected to the collector, and a negative electrode that is connected to the nozzle block in such a way that the potential of the negative electrode drops to the ground potential. The field emission device further includes an auxiliary belt device (170) which has: an auxiliary belt (172) that is made of an insulating and porous endless belt and encircles the collector; and an auxiliary belt drive unit (174) rotating the auxiliary belt at a transfer speed of the long sheet.
