Abstract A method for feeding and discharging a blow mold employs a carrier tube adjacent the mold cavity for temporarily storing a workpiece, a discharge chute coaxially above the mold cavity, cam-positioned, slidably journaled shafts for moving the tube transversely through a slot in the discharge chute into and out of mold loading position and a stop plate blocking the delivery end of the tube when in storage position. The method involves charging a preform to the carrier tube moving with the mold while a preform is being molded into an article therein, opening the mold and ejecting the article through the discharge chute and transferring the carrier tube laterally to a mold-loading position on the cavity axis within the discharge chute while removing an obstruction at the base of the tube during such movement to permit the preform to exit the tube into the mold.
A method of feeding and discharging a blow mold comprising: A. charging a preform from an upstream station to a carrier adjacent to and moving with a blow mold while a prior preform is being molded therein; B. opening the mold and forcibly discharging the article upwardly along the mold axis through a guide chute fixed with respect to the mold axis; C. transferring the carrier laterally to a mold loading position within the guide chute; and D. removing an obstruction at the base of the carrier during such transfer movement to permit the preform to exit the carrier into the mold.
