Abstract
A web crushing arrangement for a card web comprises cooperating working rolls (6,7) which are supported by a pressure-loadable support member (23), elastic pressure transmitting means (26,29) being provided between the working roll (7) and the support member (23). By supplying compressed air between the surface of the working roll (7) and the pressing surface (27), of the pressing slat (26) facing and shaped to be complementary to it, an air film is generated between the complementary surfaces.
Claims13
Web crushing apparatus for a card web comprising cooperating rolls, a pressing member which is pressable against one roll with facing complementary surfaces on the pressing member and the roll, and means for supplying air under pressure to the facing complementary pressing surfaces on the whole length of the rolls such that due to compressed air supplied, an air film is formed between the pressing member and the one roll, which film transmits the load from the pressing member to the roll and wherein the pressing member is formed by a substantially rigid member which is guided for radial movement with respect to the one roll and which is pressed against the one roll by resilient loading means.
