PURPOSE:To prevent the generation of a strain in the constituting body of a changer main body and the leakage of resin upon removing a breaker plate for cleaning, by a method wherein the changer main body is provided with a resin extracting hole at a position where the breaker plate, finished in using, is opposed to the screen of the breaker plate. CONSTITUTION:A resin extracting hole 19, having the diameter of 5-10mmphi, is provided at a position opposing to the upper part of the screen of a breaker plate whose use is finished. When a second breaker plate 3 is clogged, resin, supplied into a third breaker plate 4, is supplied to a die 8 through a resin passage 9 and one part of the resin, supplied into the second breaker plate 3, is supplied to the die 8 through the resin passage 9 while the other part of the resin is discharged out of the resin extracting hole 19 under an intermediate stage wherein the second and third breaker plates are superposed with the resin passage 9 respectively. When the replacement of the breaker plates is finished, the pressure of the resin, remaining in the second breaker plate, is released by discharging the resin through the resin extracting hole 19. |
