ABSTRACT:
A stentering machine having a drying zone and a pretreatment zone for coating a web of material on both sides and drying it is described. One aim consists of deflecting a web of material coated in the vertical position and stretched out in width, in order to introduce it into a conventional flat tenter frame, without damaging the coating. According to the invention, the web of material is needled into a pair of stentering chains having a predetermined chain pitch, and deflected from the vertical into the horizontal position on such a large arc that the difference between the sum of the chain pitches that form the arc chords and the arc length itself becomes small enough to be ignored.
