ROLLER

Номер: US20160251781A1
Принадлежит:

A roller guides and processes synthetic strand material. The roller includes a drivable roller shell. The roller shell has, on a projecting free end thereof, a cover which is effective relative to the surroundings. In order to secure the end of the roller shell relative to an operating side, the cover is freely rotatably connected to the roller shell. 1. Roller for guiding and treating synthetic strand materials , having a drivable roller shell , which has , on a projecting free front end thereof , a cover which is effective with respect to a surrounding environment , wherein the cover is connected to the roller shell in a freely rotatable manner.2. Roller as claimed in claim 1 , wherein at the front end a cover carrier is provided between the roller shell and the cover claim 1 , which cover carrier is fixedly connected to the roller shell and rotatably holds the cover.3. Roller as claimed in claim 2 , wherein the cover carrier has a central bearing bore claim 2 , in which a bearing journal is rotatably held claim 2 , and in that the cover is fixedly connected to the bearing journal.4. Roller as claimed in claim 3 , wherein the bearing journal is mounted in the cover carrier by one or more rolling bearings.5. Roller as claimed in claim 4 , wherein the roller shell is assigned a heating means on the inside claim 4 , and in that the cover at the front end is assigned a thermal insulation on an inner side or outer side.6. Roller as claimed in claim 4 , wherein the cover is formed from an inner cover and an outer cover claim 4 , wherein the inner cover and the outer cover encase a thermal insulation.7. Roller as claimed in claim 6 , wherein the thermal insulation is formed by a plurality of air chambers claim 6 , wherein the air chambers are uniformly distributed within the cover.8. Roller as claimed in claim 7 , wherein the air chambers are formed by circumferential grooves on a front end face of the inner cover claim 7 , which front end face is opposite a closed front ...

Method and device for melt spinning and cooling a plurality of monofilaments

Номер: US20120112381A1
Принадлежит: Oerlikon Textile GmbH and Co KG

The invention relates to a method and a device for melt spinning and cooling a plurality of monofilaments which are extruded through a plurality of openings of a spinneret and guided into a cooling bath. The removal process consists of redirecting the monofilaments within the cooling bath. According to the invention, in order to prevent adhesion and an oblique pull-off, the monofilaments are divided into multiple filament groups after extrusion, said groups consisting of multiple monofilaments, and the filament groups are individually redirected independently of each other within the cooling bath into multiple redirecting positions by separate redirecting sheaves.

Method and Apparatus for Fibrillating Synthetic Ribbons

Номер: US20130055536A1
Принадлежит: OERLIKON TEXTILE GMBH & CO.KG

The invention relates to a method and apparatus for fibrillating synthetic ribbons in an extrusion process for the production of, for example, grass fibers. The extrusion process creates a sheet of ribbons from an extruded foil or a multiplicity of extruded monofils, and stretches them conjointly. The ribbons are led side by side in a parallel arrangement along the circumference of a fibrillating roll with a partial wrap. To produce a pattern of fibrillation irrespective of the thickness of the ribbons and the elasticity of the ribbons, the invention provides that a multiplicity of short partial cuts is made in the ribbons by a plurality of successively engaging rows of blades on the fibrillating roll each having a multiplicity of projecting cutting tips. 1. A method for the fibrillation of plastic ribbons comprising:generating ribbons as a ribbon bundle from an extruded film or numerous extruded monofilamentscollectively stretching the ribbonsfeeding the stretched ribbons in parallel, adjacently, with a partial wrap about the circumference of a fibrillation roller,generating a plurality of short partial cuts are on the ribbons by a plurality of successively engaging rows of blades on the fibrillation roller, each row having a plurality of projecting cutting tips with blades.2. The method according to claim 1 , wherein at least two groups of short partial cuts are generated on the ribbons by means of offset cutting tips on two successively engaging rows of blades.3. The method according to claim 1 , wherein the ribbons are adjusted prior to and/or after the fibrillation individually or in groups in such a manner that the partial cuts are generated such that the cuts are substantially symmetrical on each ribbon and have a minimum spacing to the ribbon edges.4. The method according to wherein the fibrillation roller is driven for the generation of the partial cuts on the ribbons with a circumferential speed which is faster than a feed rate of the ribbons.5. The method ...
