| 摘要 |
The invention relates to a process for applying a plastic covering around a tube-or wire-shaped object, which comprises preparing a solution of a high molecular polyolefin, especially polyethylene or polypropylene and an organic solvent, with a concentration of between 5 and 50 wt.% and extruding said solution through an annular extrusion gap, around a tube-or wire-shaped object fed within the circumference of the gap. After discharging, stretching and substantially removing solvent from the extrudate, this is contacted with the object to be covered. The covered product is cooled and solvent is further removed from the covering. If appropriate, an after-treatment is applied to the covered object.
