Abstract
Arrangements are described which allow a printing stock web to be reliably drawn through a drier. A draw-in member which grasps the tip of a printing stock web has a power transmission, e.g. a roller chain, which runs in a guide. Plates or blowing boxes which are movable vertically to the draw-in plane of the printing stock web and form closures in the guide by lateral projections of their side walls are provided to prevent dirt from penetrating into this guide. Rollers or cylinders are provided for additional correction of a lateral displacement of the printing stock web while the web is drawn in by the draw-in member. A friction-locking engagement, i.e., particularly rolling friction or adhesive friction, causes these rollers or cylinders either to exert a transverse traction on the printing stock web themselves or, in order to compensate for the lateral displacement of the printing stock web, secure the printing stock web in the correct position due to a transverse traction produced by an oppositely directed displacement of the guide.
