Abstract

The plastic web passes from the extruder over pref. a rotatable roller, to a mould having co-operating upper and lower parts which are intermittently moved together to profile the web, and whilst one portion of the web is being moulded the roller is rotated to form the part of the web between the extruder and mould into a reserve consisting of two freely hanging loops on opposite sides of the roller. The part of the web forming the reserve is subsequently forwarded for moulding pref. by a pair of feed rolls. The web forming the reserve may be heated the method allows moulding of webs directly downstream of the extruder irrespective of the thickness of the web or depth of profiling.
