Definitions
- the invention relates to a pressure roller for a Spinning preparation machine, for interaction with a counter roll for the Moving fiber material with one roller core and one on the roller core attached cover made of rubber elastic material, with an addition of Distributed electrically conductive material at least in the region of the peripheral surface of the Coating.
- Such pressure rollers are usually used in spin mill preparation machines, e.g. Combing machines and draw frames, used in different places.
- the pressure rollers each interact with a driven counter roller in the machine Fiber material, e.g. Fiber material in the form of a fleece.
- Fiber material e.g. Fiber material in the form of a fleece.
- the object of the invention is the printing roller specified above to train that the risk of winding formation in operation is permanently reduced.
- peripheral surface of the coating is a Coating carries, which contains the finely divided electrically conductive material.
- the finely divided electrically conductive material e.g. Metal powder and / or graphite powder, serves for, electrostatic charges from the peripheral surface of the Derive coating of the pressure roller.
- the conductive material can be rubber-elastic throughout Material of the cover of the pressure roller distributed be.
- the peripheral surface of the coating has a coating made of dirt-repellent, wear-resistant plastic, especially polytetrafluoroethylene, which is finely divided contains electrically conductive material.
- a coating should be flexible and less thick have as the cover made of rubber-elastic material, for example a thickness of about 0.5 to 1 mm. So that electrostatic Charges from the coating to the machine frame
- the coating can be derived with bearing journals carried by the roller core, which at least partly made of metal, electrically conductive be connected. When the entire roll core is molded together Bearing journal made of metal, this could be electrical conductive connection be made that also the rubber-elastic material of the cover is finely divided contains electrically conductive material.
- the trunnions can consist of metal or at least coated with metal Have peripheral surfaces.
- electrically conductive element can be used, e.g. a rotatable metal roller or a metal scraper.
- the printing rollers shown each contain a roller core 1, the bearing pin 2 at its ends wearing.
- the bearing pin 2 can with the roller core 1 be integrally formed or used in this be.
- On the circumference of the roll core 1 there is a coating 3 arranged from rubber-elastic material.
- the coating 3 in turn carries a coating on its peripheral surface 4 made of a dirt-repellent, wear-resistant Plastic, preferably made of polytetrafluoroethylene (“Teflon").
- the platen roller is for use in a spinning preparation machine (not shown) determines e.g. in a combing machine or a line in which the Pressure roller cooperates with a counter roller 5.
- the Counter roll 5 is in the frame of the machine, not shown rotatably and drivably mounted.
- the pressure roller 1, 2, 3, 4 is from a loading device, also not shown pressed down against the counter roller 5 in order to Fiber material, e.g. a non-woven fabric that by rotation the counter roller 5 is to be moved towards the counter roller jam.
- an electrical conductive material e.g. Metal powder and / or graphite powder.
- Fig. 1 is the coating 4 with the bearing journal 2, which are at least partially made of metal, electrically connected, thus resulting charges can be derived from the machine frame.
- This electrically conductive connection can for example be produced that also the end faces of the coating 3 and the roller core 1 an electrically conductive coating wear which the coating 4 with the peripheral surface of the journal 2 connects.
- the bearing pins 2 usually consist entirely of metal; but they can also consist of another material, e.g. made of fiber composite material, and only on their peripheral surfaces be coated with metal.
- the roller core 1 can also consist of metal, and in such a case the said can be electrical conductive connection from the coating 4 to the Journal 2 also be made so that the coating 3 made of elastic material also finely divided contains electrically conductive material.
- FIG. 2 stands with a rotating roller 6 on the circumferential surface of the coating 4 made of metal in contact, which electric charges from the coating to the machine frame.
- Additives may be added, especially chalk flour.
