Plastic tube, especially a pneumatic tube

摘要

A plastic hose, and more particularly a pneumatic hose, is provided with at least two electrical conductors extending along the hose body. These conductors are in the form of strips ( 11 and 12 ) of a metallized braid of plastic material or of natural fiber with a spacing apart on the hose body ( 13 ). Accordingly high flexibility of the plastic hose ( 10 ) is achieved with satisfactory electrical conductivity of the strips ensuring safety as regards breakage.
