Abstract

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.

Description

The invention relates to a plastic profile, for example a plastic tube or the like, of a sheathed base material or of another, at least differently colored material, wherein the production of the plastic profile is effected by extrusion of the material.

BACKGROUND OF THE INVENTION

These plastic profiles, in particular plastic tubes, are in principle notorious. For example, to fix the color sheath and the marking strips running in line on the surface of the res. the tubes are in addition to gluing the strip, applying marking strips, etc. with the help of paint on the surface of the profile, etc. uses a technology that uses two coextuders for the profile shroud and marking strips alongside one base material extruder. Substrates for profile cladding and marking strip application etc. they may be of a different nature, for example decisive features or the application of materials of different quality to the profile itself and the jacket may be decisive.

Such processes are not very permanent on one hand (adhesive strips) and on the other hand due to the three extruders needed (one extruder and two coextruders) expensive and expensive. The challenge is to create profiles that are provided with axial strips, recesses and ridges, and are simple and affordable.

SUMMARY OF THE INVENTION

This task is fulfilled by profiles, the advantage of which is not to attach any number of identical belts, etc., in a simple manner, for example also for marking strips in or on the profile, etc. but especially in saving one coextruder, because instead of the two coextruders so far, only one is needed now, and finally in creating any pipe or tube transitions. tires; the profile casing to the strips, depressions and ridges, from smooth to straight and profiled, also in the possibility of using various materials and combinations of materials such as PE, PVC, RUR foam, etc., pastes. In addition, different colors and surface structures can be used.

BRIEF DESCRIPTION OF THE DRAWINGS

The invention is explained in more detail by way of examples. The drawings show:

Fig. 1 is a perspective view of the hollow profile of FIG. 2 shows an embodiment variant of FIG. 1 with a plurality of tubular profiles, FIG. 3 shows an embodiment variant of FIG. 2a fig. 4 shows a further embodiment variant of FIG. 2

DETAILED DESCRIPTION OF THE INVENTION

The profile P shown in FIG. 1, e.g. the rectangular hollow profile of thermoplastic, such as PE, is formed by an inner core 1 and an outer sheath 2, both of which may be of different materials, for example additionally differently colored. The casing 2 is not completely closed, on the contrary it is formed with at least one slit 3. The belt 4 visible on the surface of the P profile, for example the marking strip, is formed of a material The strip 4 is closed, for example, with the surface of the casing 2 seamlessly, but it can also be formed as an elongated profile 8 extending over the surface O of the casing 2 or as a longitudinal groove 9 as shown. FIG. Third

Fig. 2 shows a pipe connection consisting of three protective tubes R1. R2. R3 cable, wherein the cable protective tube R1 is not provided with any marking strip, the cable protective tube R2 is provided with one marking strip 4 and the cable protective tube R3 is provided with two marking strips 4 and 5. Connecting bridges between the two outer protective tubes R1 / R3 and the inner protective tube of the cable R2 are marked 6, 7.

FIG. 3, it is evident that these connecting bridges 6, 7 are embossed on the cable protective tubes R1, R2, R3 or can be clamped by means of a shaped reinforcement 6a, 6b into the longitudinal groove 9. The individual profiles P or the cable protective tubes R1, R2, R3 for example, as shown in FIG. 4 can be connected to each other by means of a groove 9 formed in the profile and from a spring 10 projecting from another profile by or without connecting bridges 6, 7.

The invention thus provides a variety of possibilities for marking, joining, etc. and its advantage is a simple production method using a simple tool.
