Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a core using a paper core (IIIJ curved blade method).

The purpose of this invention is to continuously form a core of six eaves that is stretched. The object of the present invention is to provide a core material that does not restore its shape to a plate unless stress is applied to it.

Another purpose of this invention is to streamline the core material manufacturing process, shorten the manufacturing process time, improve work efficiency, and reduce application costs. It's about trying.

The structure of this invention is as follows: A pair of upper and lower paper sheet rolls (12) is prepared (12), and the IM of these pairs is
A belt-shaped paper sheet is fed from the Ei roll by rotating it counterclockwise. Subsequently, one of the upper pair of paper sheets is submerged in water for a constant period of time in the length direction of one of the upper paper sheets, and a large number of IH perforations are submerged in water for a constant period of time, and the inner surface of this paper sheet is submerged in water. A band-shaped inner ((

Form the inner IH11 glue allowance part K on the 1st corner of the perforation (), and apply a landing agent to the inner glue allowance part of one paper sheet and the inner +1111 glue allowance part of the other paper sheet. Apply the adhesive, remove the glue margins from the pressing part, prepare a composite paper sheet, cut this paper sheet into 9 pieces at a certain length in the width direction, and throw m bodies for the paper core into litters. , On the outer surface of one of the paper sheets that together constitute the m-body for the paper core, on one side of the perforation that extends 14 to the inside @1 glue allowance, add the outer 1lffl glue allowance in the shape of a band 1j21. ,
And on the outside + tll side of the paper sheet on the fih side, form an outside 1lffl glue allowance part in the form of a band in the perforation pond 1llll located at the corner of the inner glue allowance part, and purchase the seventh vapor core Ill alone. 11-side paper sheet for external use II glue allowance and second paper core m
After applying the concubine agent to the outer side of one paper sheet, apply jiff pressure to both sides of the body.
After adhesion, the outer glue margin of the 1st paper sheet that makes up 1lffl inside the third paper container and the outer side of the 10th paper sheet that constitutes the second paper core m body. Glue area (inner eyelid agent), apply, both sexes 111 (push the glue area FJ-, adhere to I, below 181) < t 1st and above for each paper core. This is an oil refining method in which the outer adhesive part of the paper sheet is pressed and cored with a vapor core that is 1" thick.

The details of this invention will be explained below with reference to the accompanying drawings.

If one paper sheet/a is shifted by the width A of the inner glue margin S in the length direction of the paper sheet/b on the h side, then the perforation 3 of the paper sheet/a on the The gear η is pressed to form perforations 3a with a distance H equal to the distance gH, and at the same time, on the inside surface of this paper sheet /b, one of the perforations 3a and the other side of the set perforations 3a are inwardly formed. 1 [111 Glue margin, ta formed into a belt shape (~, inner glue margin j of one paper sheet 1-/a and capacity paper sheet 1-/1) +1111 Glue margin 5a formed with glue The adhesive agent is applied through the roller 7, and the glue portions 3 and 3 on both inner sides are pressed by the roller 7 to form a composite paper sheet.

This composite paper sheet is cut in the width direction with a knife g to a certain degree, and a plurality of paper core tubes are provided (see Figures 4 and 5). One of the paper seas that make up the suspension 9)/a outside tll

You are free to cut the sub-section vertically by a certain width depending on the purpose.

Since the present invention has the above configuration, it has the following advantages.

(c) Since each process of perforation, inner and outer glue margins, pressing, and cutting can be carried out continuously using the paper sheet fed continuously from the anti-roll (jb), it is possible to rationalize manufacturing work and reduce manufacturing time. It is possible to shorten the time.

Since a series of steps are carried out continuously, the quality of the product can be stabilized.

Drunkenness By increasing the efficiency of manufacturing, it can contribute to reducing production costs.
