DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of an adhesive sheet manufacturing apparatus according to the present invention, in which one delivery reel 10 is provided on the left side of the figure, and the other delivery reel is provided on the right side with a required space. 11 is provided, and adhesive papers 12 and 13 are wound in a roll shape. This roll-shaped adhesive paper 1
2 and 13 may be adhesive papers that are manufactured according to a predetermined production schedule and are in stock. The two reel-out reels 10 and 11 are configured to rotate clockwise as indicated by arrows.
Therefore, the left adhesive paper 12 has its surface material 12a on the upper side and the release paper 12b on the lower side, and the right adhesive paper 13 has its surface material 13a on the lower side and the release paper 13b on the upper side. It is paid out in the direction.

Further, one take-up reel 14 is provided on the lower side and the other take-up reel 15 is provided on the upper side, with a required interval above and below the opposite line connecting the two supply reels 10 and 11. Similarly, as shown by the arrows, they rotate in the clockwise direction.

Then, four peeling / sticking rolls 16 to 19 are provided in four directions around the intersection O between the opposing line connecting the pair of feeding reels 10 and 11 and the opposing line connecting the pair of take-up reels 14 and 15. It is provided so as to rotate clockwise or counterclockwise as indicated by.

Further, between the peeling / sticking rolls 16 and 17 and the take-up reel 14, and the peeling / sticking roll 1
Slitters 20 and 21 are provided between 8 and 19 and the take-up reel 15, respectively.

Therefore, the feeding reels 10 and 11, the peeling and sticking rolls 16 to 19 and the take-up reel 14,
By rotating 15 synchronously, the adhesive paper 12 of one of the reels 10 is peeled and stuck by the peeling and sticking rolls 16 and 18 on the way of feeding, and the adhesive paper 13 of the other reel 11 is peeled and stick. The surface material 13a and the adhesive material 22b of the adhesive paper 13 delivered from the other delivery reel 11 and the release paper of the adhesive paper 12 delivered from the one delivery reel 10 immediately after being peeled off by the rolls 17 and 19, respectively. 12b and 12b are overlapped with each other and cut into a required width by a slitter 20 and wound on one winding reel 14. Similarly, on the other take-up reel 15, the surface material 1 of the adhesive paper 12 fed from the one reel 10
2a and the adhesive material 22a and the release paper 13b of the adhesive paper 13 delivered from the other delivery reel 11 are superposed on each other and wound in a state of being cut into a required width.

When a sudden market need occurs, the surface material 13a and the adhesive material 2 which meet the market need.
The adhesive paper 13 having 2b is set on, for example, the feeding reel 11 on the right side, and the release paper 1 that meets the market needs is set.
The adhesive paper 12 having 2b is set on the left reel reel 10, and in this state, the reel reels 10, 11, the peeling / sticking rolls 16-19 and the take-up reels 14, 1
One of the take-up reels 14 is driven by rotating 5
In this case, the adhesive paper 23 having the surface material 13a, the adhesive material 22b, and the release paper 12b that meet the sudden market needs is wound up.

Further, since the adhesive paper 24 of a different type from the adhesive paper in stock is also wound up on the other take-up reel 15, this is also manufactured as the adhesive paper 24 that meets the market needs. Therefore, it is possible to manufacture the adhesive papers 23 and 24 which meet two kinds of market needs at a time.

FIG. 2 shows another embodiment of the present invention, in which peeling rolls 16a, 16b, 17a, 17b and
The sticking rolls 18a, 18b, 19a, 19b are provided separately, and the other configurations are the same as those in the above-described embodiment.
In this embodiment, the release papers 12b and 13b separated from the surface materials 12a and 13a are provided so that a back splitting cutting tool is pressed against the release rolls 16a and 17b in the flow direction, and the release papers 12b and 13b are attached to the release papers 12b and 13b. When slitting is performed in the flow direction, the release paper can be easily peeled off during use, which is desirable.

[0022]

As described above, according to the present invention, claim 1
In that case, by using various adhesive sheets that are manufactured and in stock according to a predetermined production schedule, combine these according to market needs, and re-peel the various adhesive sheets that are combined and combined. Since the surface material of the pressure-sensitive adhesive sheet will be peeled off with the pressure-sensitive adhesive material attached, the use of this pressure-sensitive adhesive material requires the surface paper and The adhesive material and the release paper can be re-adhered, which makes it possible to quickly produce a product of a quality and type that meets sudden market needs.

According to the second aspect of the present invention, a product that meets the market needs can be manufactured at a low cost by using an extremely simple structure including a pair of pay-out reels, a pair of take-up reels, and two pairs of peeling / sticking rolls. It can be manufactured.

Further, according to claim 3, the market needs are met by an extremely simple structure of a pair of delivery reels, a pair of take-up reels, a pair of peeling rolls and a pair of sticking rolls. The product can be manufactured at low cost, and the installation state of the peeling roll and the adhesive roll can be adjusted independently according to the surface material forming the adhesive paper, the adhesive material or the release material, and the adhesiveness. be able to.

According to the fourth aspect, it is possible to provide a sticking paper having a width that meets the market needs.
