Abstract: To retain compressible articles such as paper towels, toilet paper and the like tightly compressed in a weldable foil, a feeding push element (3) pushes the articles into a bag and, in accordance with the invention, the bottom of the bag is yieldingly restrained to permit movement of the articles into the bag while displacing the bag against a yielding force. When the bag is filled, the counter abutment plate (6) adjacent the bottom of the bag has reached a limit or terminal position, so that articles in the bag are compressed. Hold-down elements then close over the still open end of the bag, permitting sealing of the still open bag while the articles are retained compressed. The abutment plate can then be moved out of position for further transport of the filled bag with the material retained therein in compressed condition.
