Abstract

A sheathed elongated profile, that is, shaped product, is disclosed. The elongated profile may include a main profile body that is at least partially sheathed in a first synthetics component. The elongated profile may also include at least one disposal, that is, protrusion, on the main profile body that is not completely sheathed in the first synthetics component and at least partially sheathed in a second synthetics component. Methods and devices for producing the elongated profile are also disclosed.

First claim

What is claimed is:

1. A method for sheathing an elongated profile part, the method comprising:
providing the elongated profile part, wherein the elongated profile includes a main profile body and at least one disposal part;
sheathing, at least partially, the main profile body with a first synthetics component, such that the first synthetics component is attached to the main profile body; and
at least partially sheathing the at least one disposal part with a second synthetics component, such that the second synthetics component is attached to the disposal part,
wherein the first synthetics component is adhesively bonded to the main profile body, such that the attachment between the first synthetics component and the main profile body is stronger than the attachment between the second synthetics component and the disposal part.

2. The method according to claim 1 , wherein the first synthetics component is a self-adhesive synthetic material.

3. The method according to claim 1 , wherein the first synthetics component is extruded fluidly on the main profile body, and at the same time, the second synthetics component is extruded fluidly on the at least one disposal part.

4. The method according to claim 1 , wherein the main profile body and the at least one disposal part correspond to different portions of one piece made of the same material.

5. The method according to claim 1 , wherein the main profile body and the at least one disposal part are made of different materials.

6. The method according to claim 1 , wherein the at least one disposal part is partially sheathed with the first synthetics component so that a transitional area of the at least one disposal part, adjacent to the main profile body, is sheathed in the first synthetics component.

7. The method according to claim 1 , wherein the main profile body is a conductor having at least one layer, and the at least one disposal part is a lateral contact tab coupled to the conductor.

8. A device for sheathing a longitudinal profile, comprising:
a part having a passage for continuous throughput of the longitudinal profile, the passage having a cross-section corresponding to a cross-section of the longitudinal profile, wherein the longitudinal profile has a main profile body and at least one disposal part; and
two extrusion nozzles, located in the passage, respectively having and feeding a first synthetics component and a second synthetics component, the two extrusion nozzles respectively feeding the first and second synthetics components to at least partially sheath the main profile body in the first synthetics component, such that the first synthetics component is attached to the main profile body,
wherein the at least one disposal part is at least partially sheathed in the second synthetics component, such that the second synthetics component is attached to the disposal part, and
wherein the first synthetics component is configured to bind to the main profile body, such that the attachment between the first synthetics component and the main profile body is stronger than the attachment between the second synthetics component and the disposal part.

9. The device according to claim 8 , wherein the device has a seal that is forcibly opened when a disposal part enters the passage such that leakage of the first synthetics component and the second synthetics component is prevented.

10. The device according to claim 8 , wherein the device has a moveable element which is openable and closeable via a control system when the at least one disposal part is inserted.

11. A sheathed elongated profile which has been sheathed using extrusion, comprising:
a main profile body that is at least partially sheathed in a first synthetics component, such that the first synthetics component is attached to the main profile body; and
at least one disposal part on the main profile body that is at least partially sheathed in a second synthetics component, such that the second synthetics component is attached to the disposal part;
wherein the sheathing of the main profile body and the sheathing of the at least one disposal part are both applied in a single extrusion process, and
wherein the first synthetics component is adhesively bonded to the main profile body, such that the attachment between the first synthetics component and the main profile body is stronger than the attachment between the second synthetics component and the disposal part.

12. The profile according to claim 11 , wherein a clearance between the at least one disposal part and the main profile body is filled with the first synthetics component.
