Patent number: 4929450Abstract: In a delivery apparatus in a machine for preparing hollow vessels by delivering mandrels supporting thereon preforms and vessels through a preform-heating zone and a draw-blow-forming zone, the downward movement of a mandrel-clamping mechanism is utilized for insertion of a preform into the mandrel and the rising movement of the clamping mechanism is utilized for withdrawal of a formed vessel. By this arrangement, insertion and fixation of preforms into mandrels and withdrawal of formed vessels from mandrels can be performed continuously, assuredly and smoothly in one apparatus while saving the waste in the blow-forming operation. If the operation of reversing the clamping mechanism is added, any particular device need not be disposed for reversing preforms.Type: GrantFiled: January 14, 1988Date of Patent: May 29, 1990Assignee: Toyo Seikan Kaisha, Ltd.Inventors: Nobuyuki Takakusaki, Yohji Mizutani, Nobuhiro Kishida, Manabu Hosokawa

Patent number: 4373891Abstract: An apparatus for cooling a transfer mandrel on whose top portion a thermoplastic resin parison is mounted and which is rotatably engaged with the peripheral portion of a rotary table. The apparatus is arranged along the peripheral portion of the rotary table adapted to rotate oppositely to a heating means. The apparatus comprises a cooling block having a cavity through which cooling water flows and a concave surface opposing to the transfer mandrel which has a profile conforming to the cylindrical portion of the transfer mandrel, means for adjusting the position of the cooling block, and a spring which pushes a surface portion opposite said concave surface of the cooling block.Type: GrantFiled: June 26, 1981Date of Patent: February 15, 1983Assignee: Toyo Seikan Kaisha, Ltd.Inventors: Nobuhiro Kishida, Kunihiro Shishido, Satoshi Haryu
