ABSTRACT:
A continuous high pressure press especially adapted for molding thermosetting or thermoplastic sheet material comprises two tracks each carrying a plurality of molds which converge at the press input where sheet material is fed in. Each track is engaged by two groups of presser rails which alternately move forward while applying molding pressure and move in reverse while retracted. The pressure is applied to each rail by a hydraulic actuator acting through a pinion which meshes with a rack formed in the rail. The pinion is rotated by another hydraulic actuator carried by the piston rod of the first actuator.
