<p>A device for cross-ribbing of a diagonal strip subjected to constant pressure, in which device the constant pressure is directed at a set of cleaning rollers 12 for executing the cross-ribbing together with the cross- ribbing rollers 68, which rollers have on the surface projections 88. Each of the cleaning rollers 12 is supported in an essentially frictionless manner and the constant pressure is fed in with the aid of an elastic film 60 operating on top of the piston 56, which piston can move in an essentially frictionless manner in a pneumatic cylinder 52. <IMAGE></p> |
