PURPOSE:To save the time and labor required for replacement of members for alteration of an adaptor and passage by a method wherein a plurality of plates each having a resin passage are stacked rotatably in a cancentric manner and then, rotated. CONSTITUTION:A resin A flows along a passage 11 inside a combining adaptor 1, carried onto a concentric circle 13 passing through a passage 10 of a plate 2 and introduced to a convergence part 14 of layers passing through a passage 9. A resin B shifts onto the concentric circle 13 along the passage 10 of a plate 3 and introduced to the convergence part 14 of the layers from the different position from that of a resin A. Moreover, a resin C shifts to the concentric circle 13 along the passage 10 of a plate 5 and introduced to the convergence part of the layers from the position different from those of the resins A and B. Likewise, corresponding operation can be done with the number of layers. Otherwise, the plates 2, 3 and 5 can be turned on the axis center 12 to change the course to the convergence part 14 of the layers simply. |
