[Action]

 According to the above-mentioned device of the present invention, the feeding of the single-sided adhesive tape and the clamping of the feeding end, the tape application by the pressing plate, the tape cutting, and the releasing of the clamping are performed by the known single-sided adhesive tape (see Japanese Patent Publication No. 54-714). The same as in the above case, but the non-adhesive tape is separately fed out along with the above operation. At this time, adjust those of the non-adhesive tape with respect to the feeding speed and timing of the single-sided adhesive tape so that the non-adhesive surface remains at the upper and lower ends of the single-sided adhesive tape in the guide roll section. Set the length of the tape, cut the non-adhesive tape just before the guide roll section, and polymerize it with the single-sided adhesive tape. After that, in accordance with the action of the above-mentioned single-sided adhesive tape, the tape is unrolled, the feeding end is pinched, the lowering of the nipping tool is performed, the upper and lower parts of the one-sided adhesive tape are fixed by the pressing plate, the tape is cut, and the nip is released. Complete the side seal of the package. The side seal of the obtained roll-shaped package is due to the adhesion of the single-sided adhesive tape, but the non-adhesive tape is present in the middle part, and this part remains as the non-adhesion part, allowing the operator to grab and pull it out. To do.

The number of side seals formed by superposition of the single-sided adhesive tape and the non-adhesive tape is not limited to one, and it is also possible to use two or more side seals that cross each other.

Therefore, as shown in FIG. 2, the length of the single-sided adhesive tape T after cutting is longer than that of the non-adhesive tape T ′ as the sealing tape pressed against the end surface of the roll-shaped package R, and at least the upper and lower sides. It is necessary that the non-adhesive tape T'exists on both parts.

Then, by pressing the one-sided adhesive tape T and the non-adhesive tape T'on the end surface of the roll package R in a superposed state, as shown in FIG. It is possible to obtain the side seals which have the parts and which are fixed to each other by the one-sided adhesive tape T '.

As the non-adhesive tape T, an ordinary tape such as paper or film can be used, and the polymerization cutting of the above-mentioned one-sided adhesive tape T and the non-adhesive tape T ′ is performed by the feeding speed of the one-sided adhesive tape T, It can be determined by setting the speed timing of the non-adhesive tape T ′ whose speed is adjusted by the motor 9 with the guide roll 8 and adjusting the cutting timing of both cutters 4 and 11 with respect to the feeding speed.

Thus, the non-adhesive tape T ′ cut into a required length by operating the apparatus having the above-mentioned structure according to the above-mentioned operation description is pressure-polymerized and adhered by the guide roll 3 parts to the one-sided surface. Both the adhesive tape T and the non-adhesive tape T'are sandwiched by the sandwiching piece 6 and are stretched to the end face adhered position of the roll-shaped package R and pressed by the pressing plates 1A, 1B and the sub-pressing plates 1C, 1D to be in the middle. After the non-fixed portion is left, the roll-shaped package R is pasted and fixed to the end surface thereof, then cut by the cutter 4, the nipping is released, and the next work is performed again to complete the side seal.

In this way, as shown in FIG. 3, the roll-shaped package R placed on the support base 14, usually the roll-shaped package R wrapped around the outer periphery in the pre-packaging step, has a non-fixed portion in the middle. Because of the presence of the tape, it is possible to easily grasp the tape by the operator's hand and pull out the roll-shaped package R 3 for easy handling.
