ABSTRACT:
A first transfer mechanism of a biaxial stretch blow-forming apparatus has sliders that are transported along a circular transportation passage. The sliders slide along a circular guide rail installed on a turntable. Each of the sliders is swung to left and right by a swing arm as the turntable rotates, and a feed pitch of a preform holding groove formed in a holding plate installed at an end of each of the sliders is changed. The feed pitch can be changed by a simple mechanism. Because the holding groove always faces a radial direction, receiving and handing over actions of a preform sent along the circular transportation passage can be reliably performed.
