The lower position is used upon discharge of the loose material into the bag. The apparatus comprises dust collecting means for collecting dust within the lower section of the hollow tube when the lower section is in the lower position and the bag is filled with the loose material. The apparatus further comprises means for moving the lower section of the hollow tube along a substantially vertical axis between the raised and the lower positions.
