Abstract

The invention relates to an arrangement for pulling the tail of a web-like material through a drying or cooling plant. In such a plant the web-like material is floated on air at a given distance from a surface provided with air delivery orifices. The web-like material (10) is thereby caused to pass zig-zag over drivable reversing rolls (2), while an endless traction or pulling member (3) in the form of a belt or rope runs in a separate path through the plant, substantially parallel to the material web, and is provided with means (12,13,14,15) with the aid of which the forward web end or tail (11) is attachable for pulling through the plant. At least one of the reversing rolls (2) is adapted at one end portion for carrying the tail pulling member either directly or over a pulley (9) drivably connected to said end portion. Driving the tail traction member is performed with the same means as drive the reversing rolls. The means (13) for fixing the tail (11) to the traction member (8) has a given stretching ability for preventing the material web (10) from rupturing.
