Apparatus for manufacturing webs of synthetic thermoplastics comprises a machine frame, a cooling roller mounted in said machine frame and provided with drive means, and an extrusion die mounted in said machine frame and spaced above said cooling roller and connected to a supply line for molten plastic material and having a die slot which faces the cooling roller and is parallel to a generatrix of said roller, also comprising two electrodes, which in the direction of rotation of the cooling roller precede the slot and are disposed adjacent to the lateral end portions of the slot and mounted in the machine frame and directed toward the cooling roller, and electric cables electrically connected to the electrodes and to the cooling roller. The electrodes consist of brush electrodes consisting of wire ends arranged like a brush.

Apparatus for splicing the trailing end of a web from an exhausted supply roll to the leading end of a web from a new supply roll comprises a cutting mechanism consisting of a cutter cylinder having a single cutter and a backing cylinder and serving to make a transverse severing cut through both superimposed webs passed between said cylinders, one of which is provided in a longitudinal strip- or sector-shaped portion with suction holes for retaining the leading end of the new web behind the severing cut. The apparatus also comprises a tape-applying cylinder, which is adapted to carry a tape which is adhesive on one side, and to apply the adhesive tape to the two webs at their abutting cut edges as they pass between the tape-applying cylinder. An outwardly facing adhesive tape is secured to the leading end of the web from the new supply roll and the backing cylinder which is associated with the cutter cylinder is adapted to be rotated at a peripheral velocity that is equal to the velocity of the web from the exhausted roll and to be moved into engagement with the new supply roll, which is adapted to be accelerated to the same peripheral velocity. The backing cylinder constitutes also the backpressure cylinder associated with the tape-applying cylinder, and means are provided for moving the cutter cylinder and the tape-applying cylinder into and out of engagement with the common backing cylinder.

Overlapping sheet articles on a first suction conveyor are intermittently diverted in groups by a lowerable second suction conveyor having a direction-changing roller which can be intermittently applied to the first conveyor and moved along therewith at the same speed and then returned.
