ABSTRACT:
The press guide roll (15) or web guide roll (4) comprises a fiber-reinforced plastic roll tube (20; 6) and a wire layer (7) wound on the surface of the roll tube (20; 6) in order to form substantially peripherally directed grooves (17). On either side of the roll middle (M), complementary sections (7b, 7c) of the windings (7) are inclined slightly relative to the peripheral direction and thus form a wire layer which is mirror symmetrically disposed about the roll's middle plane (M). The web guide roll (4) therefore laterally guides and automatically centers the material web.
