INNER DECKEL TYPE T-DIE AND TEMPERATURE ADJUSTING DEVICE FOR INNER DECKEL TYPE T-DIE

摘要

PROBLEM TO BE SOLVED: To manufacture a resin sheet having a uniform thickness in its lateral direction. SOLUTION: This inner deckel type T-die has a T-die body 2 having a resin supply passage 3 for introducing a molten resin formed thereto, a pair of inner deckel parts 8 arranged in opposed relationship so as to be slidable in the lateral direction of a sheet material to prescribe the width and thickness of the formed sheet material and the heaters 9 arranged to the heater holes 9a formed to the inner deckel parts 8. The temperature adjusting device for the inner deckel type T-die 1 has thermocouples 10 for measuring the temperatures of the inner deckel parts 8 and a control means 13 for subjecting the heaters 9 to on-off control.
