Verfahren zur Herstellung von längs- und/oder quergereckten, insbesondere simultan biaxial gereckten Folienbahnen

摘要

An improved device for producing longitudinally and/or transversely drawn-out foil webs, in particular foil webs simultaneously drawn-out along two axes, is characterised in that the actual clamping means (19) that hold the edges of the foil are held and anchored, together with the nipper carriage (17) that carries them, by means of an overlying bridge (27), so as to leave a gap (29) under the bridge (27) in the cross view. A shielding wall (41) projects upwards into said gap (29). The top edge (37) of the wall (41) ends above the plane (25) of the foil web.
