Abstract:
Apparatus for forming an extended nip between a mating roll and a shoe roll for treating a product web, the shoe roll having a stationary carrier and a flexible roll shell which can rotate around the carrier and which, in the region of the extended nip, is supported on a hydrodynamically lubricated running surface of a press shoe guided on the carrier, for which purpose a device for applying lubricant to the inner side of the roll shell is provided, where, in an inlet region, the press shoe has a plurality of holes which are arranged transversely with respect to the machine running direction, are connected to a lubricant supply in order to be fed with lubricant and, for this purpose, end at the running surface, and the holes comprise restrictors whose resistance is designed for a pressure drop of 5 to 15 bar.
