Abstract
985,310. Extrusion laminating. BADISCHE ANILIN- & SODA-FABRIK A.G. Jan. 5, 1962 [Jan. 7, 1961], No. 472/62. Heading B5A. Laminated thermoplastic sheeting is produced from within die slot 3 of a flat sheeting die 1 which contains a widthwise insert 4 provided with a channel 5 and a slot 6 opening into the inlet to the die slot 3. The die 1 may be supplied with a first thermoplastic, from an extruder 8, which is divided into two streams in die distribution channel 2 by the insert 4 which is supplied with a second thermoplastic from an extruder 9. The insert 4 and the distribution channel 2 on each side thereof may also each be supplied from separate extruders to produce 3-ply laminated sheeting, with each ply of a different plastic material. Two-ply sheeting may also be produced by supplying the distributer channel 2 on each side of the insert with a separate plastic. The insert 4 may be movable towards and away from the entry to the die slot 3 and the inlets from the extruders may be arranged at the sides of the distribution channels.
