CONTINUOUS MOULDINGS AND METHODS OF PRODUCTION THEREOF

摘要

There is provided architectural moulding apparatus (10) including a supporting frame assembly (11) and a paper roll assembly (12) which delivers a continuous paper web (13) via tension and drive rollers (14) to an adhesive applicator (22) where hot melt pressure sensitive adhesive is deposited on the web (13). The glue coated paper web (13) passes over roller (24) to a profiled polystyrene core (16) at a set-up roller assembly (25). The core (16) is delivered by a core feed assembly (15) which is adapted to receive lengths of the core (16) in abutting relation. The set-up roller assembly receives the core (16) and urges the paper web (13) glue side first into the core (16) to form the moulding assembly (32) which passes to a laminating roller assembly (33) adapted to urge the glue covered web (13) into intimate contact with the profile face of the core (16). The moulding assembly (32) then passes to a series of rollers (38) adapted to progressively fold and roll the web (13) to completely wrap the core (16). The moulding assembly (32) then passes to a finishing roller assembly (37), a consolidating roller assembly (40), and a final finishing roller (41), to ensure bonding integrity between the web (13) and the core (16). The finished moulding assembly (32) passes to a flying shear assembly (42) adapted to cut the continuous moulding assembly (32).
