Title: DEVICE FOR COMPACTING POWDER MATERIAL, IN PARTICULAR CERAMIC MATERIAL
Abstract:
A device (100) for compacting a layer (MT) of powder material; the device (100) comprises a movable surface (12), which is designed to convey the layer (MT) of powder material in a predefined feeding direction (F); a compacting belt (22) positioned over the transport surface (12); a pressing station (40, 45, 50, 55), which is designed to press the compacting belt (22) towards the transport surface (12), so as to press the layer (MT) of powder material; and an expansion countering station (80), which is designed to counter the expansion of the layer (MT) of powder material downstream of the pressing station (40, 45, 50, 55) and comprises a pusher delivering a gas under pressure to create a pushing gas cushion (STR; STR*) on the compacting belt (22).
