To take a packaging material from a storage section by adhesion, and at the same time, prevent the adherent force from decreasing.

A packaging material sticking part 17a of a packaging material letting off body 7, is formed into a tacky part by an adherent tape T which is let off from a tape coil 12. Accompanying the moving operation of the packaging material letting off body 7 so that the packaging material may be taken out, a control lever 45 of a tape recovering device 40 is operated while being in contact with a cam member 52 of a control mechanism 50. By this method, a take-up drum 41 is turned to take up the adherent tape T, and the adherent part of the adherent tape T corresponding with the packaging material sticking part 17a, is switched from a used one to an unused one.
