Abstract
A helical support for radially supporting an elastically expanded insulating tube includes an extruded body consisting of a plurality of windings extending substantially parallel to each other. Each of the windings is at least partially connected at lateral edges thereof in a longitudinal direction of the helical support. The lateral edges are separably connected by at least one laser weld seam.

A helical support for radially supporting an elastically expanded insulating tube, comprising:
- an extruded body consisting of a plurality of windings extending substantially parallel to each other, each of the windings being at least partially connected at lateral edges thereof in a longitudinal direction of the helical support, the lateral edges being connected by at least one laser weld seam.
A production device for producing a helical support for radially supporting an elastically expanded insulating tube, comprising:
- a holding device having an outer circumferential face for receiving an extruded body, the holding device being rotatable about a longitudinal axis thereof;
- at least one pressure roller positioned adjacent to the holding device for receiving the extruded body there between, the pressure roller exerting pressure on the outer circumferential face of the holding device;
- and
- a laser welding device moveable relative to the holding device.
A method for producing a helical support for radially supporting an elastically expanded insulating tube, comprising:
- winding a plurality of windings from an extruded body substantially parallel to each other to form the helical support;
- and
- welding lateral edges of the adjacent windings at least partially to each other along a longitudinal direction of the helical support with laser light to form a laser weld seam.
