<p>PURPOSE: To provide an extrusion laminator capable of setting the purge time at the start time of extrusion to the optimum value corresponding to the kind of a resin, capable of preventing the wasteful discharge of a resin and capable of also efficiently performing the transfer to usual operation without delaying timing. CONSTITUTION: The purge time (t0) stored in a purge time memory part 16 is selected on the basis of the kind of a resin inputted by an input means 14 and, on condition that the measuring time (t) of a time starting measurement from the indication of operation start inputted by the input means 14 coincides with the purge time (t0), purge operation is stepwise transferred to usual operation in the optimum timing.</p> |
