SHOE UPPER MOULDING DEVICE Russian patent published in 2014 - IPC A43D11/00 

FIELD: process engineering.

SUBSTANCE: invention relates to shoe upper moulding device. The device comprises vacuum chambers arranged one above the other and having the working agent feed openings, a loading compartment composed of a vessel with a closing door, a hollow torus-shape steam generator, an evacuated vessel communicated with a vacuum pump and a control system. A fixed perforated partition is arranged between the bottom chamber and the loading compartment. The top chamber has a flat vault without a heater used as an accumulator of air forced by the vacuum pump from the bottom chamber and the evacuated vessel. Note here that, for an increase in moulding force, an extra P-pressure transducer is used connected to a computer, a conversion unit and a control solenoid to allow the compressed air feed from the air accumulator into the cylinder piston end when required.

EFFECT: provision of the controlled moulding force.
