A fence structure is described consisting of modular panels mounted on posts. The modular panels are of thermoplastic or thermoset material having a rail portion and a connector at each end for fitting over the posts. The connector has an integral expansion joint in its central passage and each connector is offset in opposite directions to the longitudinal center of the panel to provide a hinged effect with the connectors of adjacent panels in the fence. The construction is readily adaptable to sloping ground and variation in height between panels and provides simplified installation by easy alignment.

A process for embossing a twin-web of film is described wherein a length of two superimposed webs of film are heated to a temperature above the vicat softening point, then passing the webs between a pair of embossing rolls at least one of which has an engraved surface which is sufficiently cooled to cool the webs to a temperature below the vicat softening point. The embossed webs are then passed into the nip of a pair of counter rotating driven rolls each having a high friction surface, separating the webs downstream of the nip by each of the webs maintaining contact with the surface of its respective driven roll, releasing each of the webs from its respective driven roll by continuing its passage over a co-operating pick-up or nip roll and then drawing each of the webs to separate wind-up stations.
