FIELD: machine engineering.
SUBSTANCE: device for controlling the sealing comprises an electric vacuum pump, a vacuum frame. The electric vacuum pump includes two independent diaphragm pumps driven by a single electric motor and placed in the same housing. The vacuum frame includes a frame element with a moulded rubber strip installed on it. The moulded rubber strip in the area of contact with the surface of the controlled product has triangular projections, between which there are channels connected with the openings of the frame element.
EFFECT: simplification of inspections with achievement of a higher level of control, reduction of energy costs.
