Title
(DE) WALZE UND HERSTELLUNGSVERFAHREN EINER WALZE
(EN) ROLL AND METHOD FOR PRODUCING A ROLL
(FR) CYLINDRE ET PROCÉDÉ DE FABRICATION D'UN CYLINDRE
Abstract
(DE)
Walze (1) zur Behandlung von Vlies-, Textil-, Kunststoff- oder Papierwarenbahnen, mit einem Walzenträger (10) und einem um den Walzenträger (10) rotierbaren Walzenmantel (20), wobei der Walzenmantel (20) eine den arbeitenden Walzenumfang (25) bildende äußere Umfangsfläche (26) und eine innere Umfangsfläche (27) aufweist. Erfindungsgemäß ist der Walzenmantel (20) als ein einen duroplastischen Kunststoff (22) umfassender, homogener, selbsttragender Mantelkörper (21) mit einer Härte von 85 bis 95 °SHD und einem E-Modul in Längserstreckung des Mantelkörpers (21) bei Raumtemperatur von mindestens 2000 und maximal 8000 MPa und bei einer Temperatur von 70°C, vorzugsweise 120°C, von mindestens 1000 und maximal 6000 MPa ausgebildet.
(EN)
The invention relates to a roll (1) for processing nonwoven, textile, plastic or paper material webs, comprising a roll carrier (10) and a roll shell (20), which can rotate around the roller carrier (10), the roll shell (20) having an outer peripheral surface (26) forming the working roll periphery (25) and an inner peripheral surface (27). According to the invention, the roll shell (20) is designed as a homogeneous, self-supporting shell body (21) comprising a thermosetting plastic (22) and having a hardness of 85 to 95 °ShD and a modulus of elasticity in the longitudinal extent of the shell body (21) of at least 2000 and at most 8000 MPa at room temperature and of at least 1000 and at most 6000 MPa at a temperature of 70°C, preferably 120°C.
(FR)
L'invention concerne un cylindre (1) pour le traitement de bandes de non-tissé, de textile, de plastique ou de papier, comportant un porte-cylindre (10) et une chemise de cylindre (20) tournant autour du porte-cylindre (10), la chemise de cylindre (20) présentant une surface périphérique extérieure (26) formant la périphérie de cylindre de travail (25) et une surface périphérique intérieure (27). La chemise de cylindre (20) est conçue comme corps de chemise (21) autoporteur, homogène, contenant un duroplastique (22), ayant une dureté de 85 à 95 °SHD et un module d'élasticité, dans l'extension longitudinale du corps de chemise (21), de 2000 à 8000 MPa à température ambiante, et de 1000 à 6000 MPa à une température de 70 °C, de préférence de 120 °C.
