Abstract
1,220,507. Sheet-extrusion dies. BADISCHE ANILIN- & SODA-FABRIK A.G. 21 June, 1968 [23 June, 1967], No. 29708/68. Heading B5A. A sheeting die for thermoplastics comprises die lips 4, 5 which are formed by dividing a solid cylinder along or parallel to the longitudinal axis thereof and are accommodated within a cylindrical recess formed in die parts 1, 2, one or both lips being rotatable about the longitudinal axis of the recess to adjust the die aperture. As shown, die lip 4 is fixed, detachably or otherwise, to die part 2, and lip 5 is rotated by at least two levers 11 (only one visible), each of which is screw-threadedly engaged with a manually rotatable and tiltable screw 6, rotation of which pivots the lever and rotates the die lip. Each lever 11 is lockable in position by a nut 12. Also provided are a transversely adjustable restrictor bar 8, heaters 9 and thermocouple 10. Preferably the gap between lips 4, 5 converges in the downstream direction.
