PROBLEM TO BE SOLVED: To provide a lip gap setter of a thermally displacing type T-die capable of dealing with a positive error and a negative error of a thickness of a sheet or the like, with proper balance at a lip gap regulating time without operating an unbalanced force at a thermally displacing member at the same time as pushing or pulling the member by a push-bolt and a pull-bolt. SOLUTION: The lip gap setter of the thermally displacing type T-die comprises the thermally displacing member for pushing or pulling a flexible lip by a thermal displacement to regulate a lip gap, and a preset bolt coupled to the member. The bolt has the push-bolt and the pull-bolt. The lip gap setter pushes the member by the push-bolt and simultaneously pulls the member by the pull-bolt to preset the member. The push-bolt or the pull-bolt is arranged at a central axis of the member. The pull-bolt or the push-bolt is symmetrically disposed at both sides of the push-bolt or the pull-bolt with the central axis of the member as a symmetrical axis. |
