Abstract:
A process for manufacturing a continuous molding continuously by injecting a synthetic resin solution in order of precedence into a plurality of molds circulating in a line along an endless track, and by solidifying the injected solution, the molds each including a plurality of pins which can protrude up into cavities in the molds, the track including a forward path and a backward path, the backward path extending substantially horizontally or sloping down under the forward path, the front end of the forward path being positioned just under the front end of the backward path, the rear end of the forward path being positioned just under the rear end of the backward path, the continuous molding consisting of a number of moldings connected end to end by a molded top plate, the moldings being open at their bottoms, the process comprising the steps of:injecting the solution into each of the molds moving along the forward path; removing the continuous molding from each of the molds by protruding the pins into the cavities and by displacing each mold down little by little in order of precedence from the molding in close contact with the molds while the injected solution is solidifying; moving from the front end of the forward path down to the front end of the backward path the molds released from the removing step; returning the molds along the backward path; and lifting the molds from the rear end of the backward path to the rear end of the forward path.
