<p>Cylindrical metal casings, contg. electric modules are lined with a blown plastic foil by a skin pack technique. Prior to the actual lining operating, the plastic foil is blown through the outer ring against a plane stretch limiter, consisting of a large-mesh wire grating. This makes the skin pack technique suitable for casings of large dia. and eliminates the formation of bulges at the bottom of air inclusions.</p> |
