FLAT BLOW MOLDER

摘要

PURPOSE:To provide a flat blow molder capable of injecting a flat parison of which a wall thickness is uniform and free from bending by preventing a bias and a deflection of a flat mandrel. CONSTITUTION:A compressing roller 19 which prevents a bias and a defelction of a flat mandrel 11 by pinching the flat mandrel 11 from both sides is provided on both left and right sides of the flat mandrel 11 above an accumulator chamber 3. Besides, an actuator 21 which separates the compressing roller 19 from the flat mandrel 11 in order to prevent contact of the flat spindle 5 with the compressing roller 19 when the flat spindle 5 is at a rise position, is provided.
