<p>The plastics profile (P), such as a tube, is composed of a base material (1) with a shrouding (2) of a different material and at least in another color. The shrouding (2) has at least one axial gap (3), to take projecting base material through it. Both materials have different colors and/or surface structures. The base material (1) of the profile body only partially fills the gap (3) along the shrouding (2), or it fills the gap (3) wholly to lie flush with the shrouding surface (O) or projects to form a longitudinal rib profile (8). The shrouding (2) has a smooth and sliding surface. The base material fills the gap (3) in the outer shrouding as a marking stripe, visible on the outer surface (O) of the shrouding (2). The plastics profile (P) can be formed as a tongue and groove (9) at the gap (3) zone. The profile (P) is produced by coextrusion.</p> |
