The bonding surface between the second base paper B and the fine grain composite roll 3 is defined as an outer surface H1, and the bonding surface between the second base paper B and the first base paper a is defined as an inner surface H2 (in this case, the inner surface H2 of the second base paper B and the inner surface F2 of the first base paper a are bonded together between the emboss roll 1 and the fine grain composite roll 3). Thus, when viewed from the inner surface H2 of the second base paper B, a second texture B1 in a convex shape is observed; when viewed from the outer surface H1 of the second base paper B, a second texture B1 in a concave shape can be observed.

Further, according to different product requirements, the pattern lug boss 11 can be simultaneously press-fitted with one or more composite fine points 31, so as to form one or more composite point positions C in the overlapping area D. Therefore, the number of the compound points C in the overlap region D of the present embodiment can be adaptively adjusted according to actual production requirements, and one or two or three or more compound points C can be formed in one overlap region D, so as to realize that the first base paper a and the second base paper B are pressed together to obtain a required compound paper product.

Further, the first base paper a or the second base paper B of the present embodiment may be one or more layers of combined paper, wherein the first base paper a may be one or more layers of combined paper, and a part of the layers or the whole layers may be pre-embossed sequentially or multiple times by one or more pre-embossing roller sets (not shown), and then fed between the pressing roller 2 and the embossing roller 1 to form the intaglio pattern a1 by embossing. Similarly, the second base paper B may be one or more layers of combined paper, and a part of or all of the layers may be pre-embossed sequentially or multiple times by one or more pre-embossing roller sets (not shown), and then fed between the embossing roller 1 and the fine grain composite roller 3.

Further, for the first base paper a or the first base paper B bonded by the multi-layer paper, the thickness is relatively thicker, and thus, when viewed from the inner surface F2 of the first base paper a, the depth of the first texture a12 formed at this time is relatively deeper, and a remarkable concave shape is presented; when viewed from the outer surface H1 of the second base paper B, the second texture B1 formed is observed to be relatively deeper in depth, and to exhibit a noticeable dent shape. On the contrary, for the first base paper a or the second base paper B combined by a single-layer paper or a thin paper, the thickness is relatively thinner, and thus, when viewed from the inner surface F2 of the first base paper a, the depth of the first texture a12 formed at this time is relatively shallower, and the dent shape may not be obvious; when the outer surface H1 of the second base paper B is observed, the depth of the formed second texture B1 is relatively shallow, and the outer surface H1 of the second base paper B may not exhibit obvious concave shapes, so that the observer can visually feel that the outer surface H1 of the second base paper B is a flat surface.

The non-glue compounding device of another embodiment as shown in fig. 12 further includes at least one set of pre-embossing roller set 4 for embossing the second base paper B, wherein the pre-embossing roller set 4 includes pre-embossing rollers and press rollers which are abutted against each other, so that the second base paper B is embossed by the pre-embossing roller set 4 in advance and then enters the fine grain compounding roller 3 and the roller surface of the embossing roller 1 together with the first base paper a to complete non-glue lamination and non-glue compounding, and thus the non-glue laminated compound paper has thicker thickness and softer hand feeling. The fine grain composite roller 3 may have the composite fine dots 31 disposed in a position area (for example, a kitchen composite paper product) that avoids the grain pattern formed by pre-embossing the second base paper B, so as to avoid damaging the grain pattern. In addition, the fine dots 31 of the fine grain composite roller 3 can be partially or completely overlapped with the position area of the grain pattern formed by the pre-embossing of the second base paper B (such as a paper product of a sanitary reel), and a person skilled in the art can select a proper mode as required.

Further, as shown in fig. 13 and 14, the second base paper B is embossed by at least one set of pre-embossing roller set 4 to form a plurality of pre-embossed patterns B2 arranged in order, so that the surface patterns of the second base paper B are enriched, and the non-adhesive composite paper has richer patterns, strong water absorption and locking capabilities, strong stereoscopic impression, strong layering, soft hand feeling and good fluffiness.

The above-described embodiments are merely preferred embodiments of the present invention, which are not intended to limit the present invention in any way. Those skilled in the art can make many changes, modifications, and equivalents of the embodiments of the invention without departing from the scope of the invention. Therefore, the content of the technical scheme of the utility model, according to the equivalent change made by the idea of the utility model, should be covered in the protection scope of the utility model.
