ABSTRACT:
In a molding machine for soap and similar materials, the control systems applied to the feed, molding, processing and discharge members totally or partially consist of pneumatic and/or oleodynamic pistons. The control systems are preferably applied to the grippers of the pieces to be molded, to the mobile upper mold, to the centering device and to the device controlling the rotation of the lower die and to the device for controlling the sucker type extraction of the pieces already molded. The control systems of this invention can totally or partially replace the present control systems of mechanical type. The combination of conventional mechanical systems with those of this invention may vary according to individual requirements.
