Abstract

PURPOSE: To prevent the inclusion of foreign matters as far as possible, by feeding a fluid plastic material from a single pipe to a position between a pair of calender rolls, forming a dwelling part of the material that extends throughout the whole width of the rolls, and delivering the material evenly.
CONSTITUTION: While laminate sheets 4, 5 are fed from opposite directions to the pair of the calender rolls 1, 2 with a prescribed nip therebetween, the fluid plastic material 6 is fed therebetween and a plastic molded sheet 7 is delivered from the nip. In this case, the fluid plastic material is fed to an optional position between the calender rolls from a pipe 10 to form the dwelling part of the fluid plastic material throughout the whole width of the calender rolls 1, 2 upstream of the nip. The dwelled material is evenly delivered to produce the plastic sheet. The diameter of the pipe 10 is preferably up to 1/30 of the width of the rolls.
