The invention is based on a plastic film for producing a plastic jacket for a thermal, Cold or sound insulation of a pipeline, a container or an apparatus in which of the Plastic film wound on a supply roll in the circumference of the insulation to be sheathed plus an overlap allowance, the corresponding piece is cut off and placed around the pipeline and is connected at the cut edges.

The problem still to be solved with the invention of this acquaintance is to be seen in To improve plastic films of the type mentioned so far that with simple adjustment possibility of the jacket to the most varied of pipe diameters, the simplest possible application of the jacket is also possible for unskilled workers.

To solve this problem, the invention provides that the "plastic film has a tendency to roll, that the film section has the shape of a closed tube, corresponding to the diameter of the to be sheathed Isolation, assumes.

This plastic film makes it possible to adapt to a wide variety of pipe diameters on the one hand and on the other hand to facilitate easy application even by unskilled workers, because only the plastic sheath in its length of one suitable for the respective insulation Roll must be cut off and then already has the corresponding rolling tendency, resiliently expanded and then folded over the pipe insulation. This work is also child's play unskilled workers perform.

The invention is explained in more detail using an exemplary embodiment in conjunction with the drawing explained. Here shows

Fi g. 1 is a perspective view of a supply roll with the plastic film from which a piece has been unwound and is shown bent up,

2 shows a perspective view of a film section ready for assembly, the film section is shown with solid lines in the open state, while with dashed lines Lines indicate the shape that the film section will take on due to its tendency to roll strives

3 is a side view of an insulated pipeline with the jacket,

F i g. 4 shows a side view in the plane IV-IV of FIG. 3.

The drawing shows the method steps for the method for producing a plastic jacket for a heat, cold or sound insulation plastic film for producing a

tion of a pipeline, a container or apparatus in which one on a supply roll 1 wound plastic film on the circumference of the insulation to be sheathed 4 plus an overlap allowance corresponding piece 2 is cut to see the pipeline 3 is laid and connected at the cut edges.

A plastic film is used with such a permanent rolling tendency that the film section 2 the shape of a closed pipe, corresponding to the diameter of the pipe to be sheathed Insulation 4, adopts.

In the case of the plastic film, the tendency to roll is carried out in such a way that the plastic coating is applied to a diameter range from the minimum diameter in question to the largest Diameter of any conceivable size is possible.
