Abstract
The present invention relates to a sheet assembly with a permeability at least to gaseous media, as well as a method for manufacturing same. The object of the present invention is to produce a sheet assembly which may be used as a forming fabric, press fabric and/or drying fabric, including as a press felt or drying felt. This object is achieved in that a sheet assembly according to the present invention is characterized by a foil (1) of a substantially liquid impermeable material which is coordinated with a reinforcement structure (3) which is disposed wholly or partially within the foil (1) and is permeable to gas and possibly also to liquid, at least the foil (1) displaying substantially vertical through-channels (2).
