Abstract

PURPOSE:To facilitate fine adjustment of the thickness of an extrusion sheet by providing a hole for measuring the distance from a certain reference surface to a chalk bar or a movable lip at the main die body, at a part of the main die body positioned in opposite to a choke bar or movable lip. CONSTITUTION:The main die body 1 is provided with a lip consisting of a stationary lip member 2a, and a movable lip 24. The movable lip member 2b is moved upward and downward by means of a center screw mechanism 3 to set the opening degree l of the lip at a predetermined fundamental value. A choke bar 4 is provided in contact with the rear part of the movable lip member Qb. The choke bar 4 is adjustable of its relative position between the main die body 1 and the stationary lip member 2a by means of a screw mechanism 5 engaged with the main die body 1 and the choke bar 4. A hole 10 is provided along the center axis within the male screw 6. This hole 10 is for measuring the distance from a certain reference surface L to the surface 4a of the choke bar. For measuring the opening degree y of the choke bar, the distance x between a summit a of an antenna 11, and the reference surface L, is first measured.
