Abstract: A device for laying a plastic film on a roller (7), especially a molten plastic film on a drying roller (7), with an air squeegee (15) having an air outlet aperture (25) extending transversely above the foil web (1), is integrated into the air squeegee (15) for edge blowing and is arranged in such a way that a common shared effective pressure application line is produced, and/or the air outlet apertures (27) of the air squeegee (15) can be adjusted along said air squeegee (15) and thus to differing effective widths across the foil web.

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

Abstract: An improved transport device for a moving material web, in particular a stretching system for plastic film webs which is in particular suitable for high circulating speeds, is distinguished by the fact that a guide rail system (3) comprising at least one guide rail (3', 3") and along which tenter elements (1) can be moved by means of a linear motor drive (5), is integrally incorporated in the relevant linear motor (5', 5"). The respective tenter element (1) is supported with respect to the guide rail system (3) by means of a sliding bearing or a combined sliding and roller bearing.

Abstract: An improved transport device for a moving material web, in particular a stretching system for plastic film webs, comprises tenter elements (1) which can be moved along a guide rail system (3) on both sides of the material web (11). In this case, on both sides of the moving material web (11), a linear motor (5', 5") and a guide rail (3', 3") are provided, preferably in each case at least above and below the moving material web (11). The sequence of the guide rails located above, in relation to the linear motor, is opposite with respect to the moving material web, to the linear motors located below and the guide rail located below. In an alternative preferred embodiment, a maximum vertical and a maximum horizontal distance (a, b) are provided between a point of intersection (S) at the clamping point of the material web (11), which distance is selected such that the tenter mounting is stressed as little as possible.

Abstract: A device for crosswise stretching and fixing of plastic sheeting includes a chain carriage (5) which has an positionally adjustable first roller (7') and a second roller (7) mounted thereon. Tension, resulting from tractive forces transmitted when the chain carriage (5) travels in a running direction, is translated into a prestress force directed substantially in the crosswise direction of a guide rail (11). The prestress force holds the adjustable first roller (7') in constant prestress contact with a first running surface (1") of the guide rail and the second roller (7') in steady contact against a second running surface (1') of the guide rail.
