These materials are received in separate metering devices that are able to move over a bench, being placed over the mould in accordance with a specific sequence of discharge and movements. It is defined by a fixed perimeter frame (10, 32) with apertures (12, 33) of the dimensions of the door, in which slides, snugly, a first framework (11, 34) and a second framework (14, 35) that can be moved inside the first framework and whose hollow is occupied by a series of pads or blocks (21, 22, 36, 37, 38) that can move independently through the action of respective cylinders (39, 40, 41) in order to occupy the raised position, forming the voids (15, 16, 29) for panelling or glazing, if any.
