Abstract
An extrusion blow molding method includes detecting an exit velocity of a tube exiting a head during a blow molding cycle for forming the tube. A melt accumulator receives part of the melt conveyed by an extruder or discharges melt in addition to the melt conveyed by the extruder in dependence on the detected exit velocity. The melt accumulator discharges melt if the detected exit velocity is less than a target value for the exit velocity and receives melt if the detected exit velocity is greater than the target value for the exit velocity.
