Abstract

PROBLEM TO BE SOLVED: To improve efficiency and to make a simplified apparatus by forming double corrugated paper sheets by a method in which two paper sheets are passed between stepped rollers of a pair, a flat paper sheet is laminated on each of the sheets, and two corrugated paper laminated paper sheets are produced simultaneously. SOLUTION: Four base paper 1 rolls are provided, and processing into corrugate paper 3 is done by passage between stepped rollers 2 having the middle paper 10 of the base paper 1 and paper 11 in a pair. Paste is applied to the step top part 4 to the paper 10 by an applicator with the corrugated paper 3 arranged in parallel to the other roller 2, and paper 9 is laid on it simultaneously and pressed between the other roller 2 and a roller 14. Next, paste is applied to the step top part 4 of the corrugated paper 3 of the paper 11 with a pasting tool 15 and pressed with a roller 16 from above during the application, paper 12 is laminated on the paste-applied paper, and laminated paper 6 is passed between a roller 18 and a roller 19 and taken up by separate winding rods 7 to make corrugated paper 8.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stepping apparatus for producing corrugated paper and embossed laminated paper.

[0002]

2. Description of the Related Art A conventional stacking device can only produce one piece of corrugated paper. Further, in an apparatus capable of producing two corrugated paperboards simultaneously, there is a method of producing two sheets of a matte packing wrapping paper of Japanese Patent Application No. 44-016606, which is the same applicant, simultaneously. In this method, two cores of corrugated paper were manufactured by forming a core with a corrugating roller.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to develop a simplified apparatus which can increase the efficiency by manufacturing two sheets simultaneously.

[0004]

In order to achieve the above object, a pair of stepped rollers is formed, and two base papers are formed between the stepped rollers to form a cardboard. The paper is laminated to produce two pieces of corrugated laminated paper at the same time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1 which is a schematic left side view, arrows indicate the direction of travel, and there are four base papers 1 wound in a roll shape. From the back into a paper 9, b paper 10, c paper 11, and d paper 12, and pass through a stepped roller 2 having a pair of central b paper 10 and c paper 11 to be processed into corrugated paper 3. The glue is applied to the top 4 of the b-paper 10 with the a gluing tool 13 in a state where the two-ply corrugated paper 3 is along the other stepped roller 2. The a-paper 9 is overlapped, the glued portion is firmly adhered by sandwiching and pressing between the other stepped roller 2 and the a-roller 14, and then the step of the c-sheet 11 of the sheet 3 of the lower surface is formed. Glue is applied to the top part 4 with the b-gluing tool 15, and b
The glue is surely applied by pressing with the roller 16, and the d paper 12 which is the flat paper 5 is overlapped on the c paper to which the glue is applied, and the lamination is overlapped between the c roller 18 and the d roller 19. By passing the paper 6 through, the adhesion of the flat paper 5 finally bonded is strengthened, and each of the laminated papers 6 processed in the above-mentioned process and in a two-ply state is taken up by a separate take-up rod 7 and stepped up. It is desirable that the roll paper 8 is provided, and the take-up rod 7 is provided with a suction hole 17 for sucking air, and the end of the bonding paper 6 overlapping the pair by the suction hole 17 on the flat paper 5 side. It is possible to suck, easily separate and wind, and the shape of the stepping roller 2 may be a stepping roller for producing corrugated paper into a linear step. An embossed roller may be used by forming a step.

[0006]

The production efficiency is doubled by simultaneously manufacturing the corrugated paper, and by processing the base paper by stacking two base papers, only one pair of stepped rollers is required, so that the structure of the apparatus can be simplified.
