Apparatus and method for producing polygonal hollow profiles, as well as polygonal hollow profile

摘要

Device for producing polygonal hollow profiles with a base frame (2) and an upright mounting wall (10), which is a rotatable winding core (7) polygonal cross section with a drive (6) on which a vorgerillter supplied via feed rollers (29) can be wound film strips (60), wherein the film strip (60) on both edges fold preforms, of which adjacent during winding and nesting in each other to form a fold is to be closed, wherein in the mounting wall (10) concentrically with respect to the axis of rotation of the winding hub (7) mounted shafts (16) with rockers (20) are arranged, on the winding core (7) directed roller tools (30), characterized in that at least a first molding roll (41) and a second molding roll (42) are provided which, in the axial direction of the hollow profile to be produced outside of the winding hub (7) are arranged, wherein the first molding roll (41) on the outer side of the tube and the second molding roll (42) on the inner side of the tube is arranged and at least one of the shaping rollers (41, 42) in such a way with the film strip (60) in..
