PREFORM CONVEYING DEVICE AND PREFORM MANUFACTURING EQUIPMENT

摘要

The opening side of a preform 2 is covered with a sealing disk 32, and the interior of the preform 2 is evacuated to bring the preform 2 into intimate contact with the sealing disk 32, thereby holding the preform 2 to a moving frame 31. Even the wide-mouthed preform 2 having a wide opening is appropriately held to the moving frame 31, without the use of a gripping mechanism having a great gripping force.
