Document Type and Number:
Japanese Patent JP2968576
Kind Code:
B2
Abstract:
PURPOSE:To solidify, extrude and produce a tabular body having desired wall thickness efficiently by vertically moving at least one plate of an upper plate and a lower plate constituting a movable block by a thickness regulator and bringing the clearance of the inner recessed section of the movable block to an adjustable state. CONSTITUTION:A format 2 installed between the adapter 11 of the nose section of an extruder 1 and a take-up gear 3 is constituted by pivotally supporting and connecting a fixing block 21, a connecting block 22, a movable block 23, etc., mutually from the extruder 1 side. At least one plate of an upper plate 231 and a lower plate 231' organizing the movable block 23 is shifted vertically by thickness regulators 25, 25', and the clearance of the inner recessed section (b) of the movable block 23 is brought to an adjustable state. A molten resin A is discharged from a nozzle hole (a), is spread into the inner recessed section (b) by a spreader 210, reaches the connecting block 22 while receiving the braking of the take-up gear 3 and wall thickness is increased, and the resin is regulated in specified thickness in the cooled movable block 23 and shaped.
