ABSTRACT:
A blow molding apparatus having two rows of holding plates each for holding a plurality of preforms; supporting and conveying means for conveying the two rows of holding plates into a blow molding station while slidably supporting the holding plates so that the row pitch in the rows is variable; two rows of blow molds arranged in the blow molding station corresponding to the two rows of holding plates, each row of the blow molds being adapted to blow mold the preforms; and a linkage for changing and setting the row pitch in the rows of holding plates. The linkage includes two first support shafts arranged respectively on the opposite end faces of the two rows of holding plates in a direction perpendicular to the direction of the pitch; two first links each rotatably supported around the corresponding one of the first support shafts; and two second support shafts each for rotatably supporting the other end of the corresponding one of the first link in the coaxial or non-coaxial manner, whereby the row pitch of the holding plate rows can be changed by the vertical movement of the second support shafts.
