ABSTRACT:
A device for applying pressure to the surface of an advancing workpiece has at least one continuous belt forced against the belt by fluid introduced into an inflatable pad demarcated by part of one of the pressure-application belt's strands, on the side facing the strand by a rectangular slab, and at the longitudinal and transverse edges of the slab in terms of the direction the belt travels in by a sealing strip of plastic or similar material at the edge of the slab and resting against the belt. Such sealing strips are exposed to high pressures and temperatures. To increase their life, solid shapes of a solid lubricant are accordingly embedded at intervals in the sealing strip with an active surface exposed against the associated strand of the belt.
