FIELD: mechanical engineering. SUBSTANCE: contact surface of upper working plate of the press is located above the plane where lower end of resilient member of upper part of screen is disposed at distance equal to value of vertical travel of lower part of screen. This value corresponds to deformation of resilient member necessary for its electric locking. Depth of container is chosen equal to the height of electrodes of working condenser with welding parts. EFFECT: improved structure. 2 dwg
