FIELD: ceramic industry.
SUBSTANCE: invention relates to powder material compaction and can be used during ceramic tiles moulding. Powder material layer pressing device comprises transfer surface, located below it pressing surface and flexible pressing surface. Latter is installed with transfer surface overlapping. Device includes pressing facilities, made with possibility to press pressing surface against transfer surface, as well as flexible and resilient pliable facility to hold powder material layer in transverse direction. Layer expansion compensation is provided by facilities, located after pressing facilities in powder material layer movement direction. Said compensation facilities are separated from pressing facilities and comprise lower and upper plates. Upper plate has at least three pistons, each of which is located in direct contact with upper pressing surface and connected with control unit. Latter performs independent control over each piston, acting with differential pressure.
EFFECT: result is provision of compensation pressure constant value applied to layer along entire width of powder material layer.
