Abstract:
A device for feeding a curable, liquid-containing material into, through and out of the device, the device comprising:a trough having a longitudinal, axial direction of extension;a conveying screw rotatably disposed in the trough and having a rotation axis extending axially of the trough, the conveying screw being shaped and the trough being shaped and positioned such that rotation of the screw around the rotation axis conveys the material downstream axially through the trough, the trough and the conveying screw having an upstream end and a downstream end with respect to the conveyance of material through the trough; the conveying screw being generally cylindrical and the screw having such a diameter and the axis of the screw being so placed that the height of the conveying screw in the trough is taller than the maximum filling level of material in the trough:a barrier at the downstream end of the trough preventing exit of material from the trough; anda transfer device at the downstream end of the trough comprising an element which bridges and passes through the barrier for conveying the material through the barrier and out of the trough;the transfer device further comprising a conveyor rotatably disposed in the trough and rotatable around the rotation axis of the conveyor screw; the conveyor being shaped for raising material from the bottom of the trough to an upraised position, and for there transferring the upraised material to the element.
