Abstract A process for handling workpieces by sequentially loading them into holder portions of continuously moving carrier assemblies, simultaneously abruptly shifting a group of such holders to workpiece-release positions at a discharge station while continuing movement of the carrier assemblies back toward the loading stations, and resetting the holders prior to arrival at the loading station in order to receive additional workpieces. The apparatus includes a holder trip mechanism portion of each carrier assembly, means supporting such assemblies for sequential movement along an endless path, an actuating assembly for simultaneously triggering the trip mechanisms of a group of the carrier assemblies at the discharge station and reset means for returning the holders to workpiece-engaging positions. The process and apparatus is especially adapted for use in combination with a system for temperature-conditioning elongated molded parts.
An intergral workpiece carrier assembly comprising: A. post means; B. pivotal holder means associated with the post means including arms for supporting the workpiece; C. a trip mechanism mounted with and biasing the arms to a workpiece release position; D. means for cooperating with nearby position-changing means for returning said holder means to a workpiece-engaging attitude; and E. a funnel mounted to said holder means above the arms for guiding the workpiece into engagement with the arms.
