Embodiment Construction

[0025] figure 1 An exemplary embodiment of a device according to the invention for carrying out the method according to the invention is shown schematically in FIG. This embodiment relates to a device for producing small film strips from extruded film.

[0026] For this purpose, a spinning device 1 is formed by an extruder 1.1 and a spinning head 1.2. The spinning head 1.2 comprises continuous extrusion means to extrude a film from the thermoplastic melt supplied through the extruder 1.1. The extruded film 3 here enters a cooling bath 4 arranged below the spinning head 1.2, so that the film 3 solidifies on its surface. The film 3 is guided via a first roller conveyor 5 to a cutting device 6 . For this purpose, the first roller conveyor 5 has a plurality of driven rollers 13 , on the circumference of which the film is guided partially wraparound.

[0027] In the cutting device 6 individual knives cut into the film 3 in order to cut the film sheet into bundles of small film ...

Abstract

The invention relates to a method and to a device for producing strand-shaped goods in the form of small bands, fiber strands, monofilaments, or films, which are extruded from a polymer melt. After cooling in a cooling bath, a thermal treatment occurs between rolling feed units, wherein the goods are brought into contact with a hot medium. In order to be able to perform an individual thermal treatment depending on the thermoplastic material, the hot medium is provided optionally in the form of hot air or hot water according to the invention. For this purpose, the heating apparatus is formed from a forced-air oven and a water bath apparatus, which can be optionally activated to thermally treat the goods.

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 for the production of strip-like (bundle / continuous) articles in the form of tapes, fiber strips, monofilaments or films and a preamble of claim 5 The device for performing the method described in the prologue. Background technique [0002] A method of this type as well as an apparatus of this type are known, for example, from DE 102 41 371 A1. [0003] In said known method and known device, a plurality of small film strips are produced from an extruded film. The film was extruded from a polymer melt and cooled in a water bath. After cooling, the film was cut into small strips. The small film strips are drawn together as bundles via roller conveyors and stretched between two adjacent roller conveyors. For stretching, the individual small film webs are guided jointly through a heating device in which they are heated to the stretching temperature by means of heated air. The heat ...
