ABSTRACT:
For molding complex mechanical components from plastic material in sheets, any portions of the material projecting from the mold are folded about the respective edges of the mold. The sheets are transferred to the mold on a number of retractable bars moving in relation to at least one reference bar; and a finger is moved towards the mold by an articulated parallelogram mechanism, and is mounted on a supporting bar located between two adjacent retractable bars and adjustable for so orienting the finger as to fold the projecting portion of sheet material in either one of two opposite directions.
