Description

[0001] The present invention relates to an edge saver for a paper manufacturing apparatus,

More particularly, the present invention relates to an edge saver for a papermaking machine, and more particularly, to a wire part of a papermaking machine, in particular, a medicine injected into a top ply including a pulper is separated from a filler ply and a bottom ply, To an edge saver that can be improved.

A general paper making apparatus will be described with reference to FIG.

A wire part 10, which includes water, cellulose fibers, a liquid carrier, and the like, and which is further provided with a pulper as the case may be, A press part 20 in which a transferred material (hereinafter referred to as a paper making raw material) is compressed to form a canvas while water is removed in a second order, a dryer part 30 to be further dried, A rear calender part 40, a reel part 50 and a winder part 60, and the like.

For example, a typical three-ply tributary production process will be described in detail. A top ply filler 11, a filler ply, And a bottom ply fixing unit 13 and head boxes 11A, 12A and 13A for supplying papermaking raw materials are respectively provided on the upstream side .

The papermaking materials of the top ply, the filler ply and the bottom ply are lapped together with the part of the water being removed and transferred to the press part 20. In this process, the papermaking materials are also removed, The papermaking raw material mixture is introduced into the wire pit 15 without being discarded and mixed and then reintroduced into the wire part 10 process.

However, in the case of the top ply process, unlike the filler ply process and the bottom ply process, the outer surface of the finally produced triboelectric fluid and the printed surface are formed, so that a high-priced pulper is injected into the head box 11A. If the raw materials re-introduced in the ply process are mixed together at the wire pit 15, it is difficult to collect only the pulp, which can not be put into the top ply process.

In addition, edge trimming must be performed in each step of the conventional general wire part 10. For example, if the width of the wire portion is 5000 mm at the time of being inserted in the head boxes 11A, 12A, and 13A, edge trimming is performed by 100 mm when transmitted to the press part 20, . The edge trimmed paper stock is recovered through the wire pit 15 or the like as described above.

Here, the efficiency of the productivity decreases because the edge trimmed to reduce the width results in damage to the final production paper. Since the edge trimming itself is a necessary process, it can be considered that if the amount of the paper material damaged by the edge trimming is reduced, the productivity efficiency can be increased accordingly.
