Description

[0004]
On the other hand, this type of tissue paper is bonded to the plies (thin paper layers) by embossing so as not to separate in use. For this reason, in the conventional equipment provided with the above-mentioned ply machine and inter folder separately, for example, as shown in FIG. 9, it is between ply machine 100 after superposing primary continuous sheets 101 and 102 until winding. The embossing bonding was performed by the embossing roll 120.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail.
(Example of inter folder)
FIG. 1 shows a folded plate type inter folder 1 targeted by the present invention. In the figure, the secondary source roll R which is set in the master roll support 2 inter folder 1 is shown. The required number of secondary original rolls R are set side by side in the direction perpendicular to the plane of the drawing, and in the case of this example, they are slit to the width of the product tissue by a ply machine not shown in advance. The original roll R wound in a multiple width of, for example, a double width is set. In addition, as a ply machine, the thing of the structure which abbreviate | omitted the embossing roll 120 from what is shown in above-mentioned FIG. 9 is used suitably.

(About the present invention)
The present invention is intended to perform embossing bonding of plies to each other prior to folding in such an inter-folder. Specifically, extending from the sheet roll support 2 as shown in FIG. 1 the sheet guide path to the folding mechanism 20, particularly preferably from the outlet side of the slitter equipment (not shown) to the folding mechanism 20 sheet It is recommended to provide the embossing bonding device 10 in the guiding path. As this embossing joining apparatus 10, as shown also in FIG. 8 for example, it has a pair of rolls 11 and 12 which have the embossing convex part 11a in one roll 11 outer peripheral surface, Sheet 3A, 3B between this rolls 11 and 12 It is desirable to use an embossing process. Thus, it is possible to emboss and join the plies to the sheets 3A and 3B which are being transferred from the raw fabric roll support portion 2 to the folding mechanism portion 20. As an operating speed of the inter folder at this time, it is desirable to set it as 150 m / min or less, especially 120-140 m / min.

(Others)
Needless to say, the present invention can be applied not only to the folded plate type inter folder as in the above example but also to other types, for example, a roll type inter folder. Further, the present invention is, for example, a type in which an original roll of the same width as the product tissue is set, or a slitter having a width twice or more the product tissue width and provided in the inter folder prior to folding. can also be Rukoto applied type or the like to divide the continuous sheet product tissue width, with respect to known inter folders by. However, the present invention is an inter-folder in which the original fabric roll R which is slit to the width of the product tissue paper by the ply machine in advance and wound with multiple widths of the product tissue paper is set as in the illustrated example. Particularly preferred.
