ABSTRACT:
An apparatus for packaging a stack of goods by shrinking a shrinkable foil covering on it comprises a delivery mechanism for drawing a foil tubing from a roll of tubing which cuts away a piece from the foil tubing and closes the top of that piece by an end weld seam, and a framelike vertically movable shrinking mechanism which heats all sides of the piece covering the stack of goods. To avoid a premature shrinking of the shrinkable foil covering or the foil tubing a nozzle device for making an air curtain extending substantially horizontally is provided under the delivery mechanism but above the range of travel of the shrinking mechanism and a blower for providing the air flow for the air curtain is connected with the nozzle device.
