Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a papermaking and molding technique suitable for manufacturing a three-dimensional papermaking product having a relatively bulky shape, such as a disposable container for a bento box, etc., and particularly, an efficient production of the papermaking product. And a papermaking and forming method and apparatus that enable continuous use of the forming carrier net.

2. Description of the Related Art In a conventional papermaking and molding apparatus, a carrier net is individually provided in each of the papermaking apparatus and the dehydration / drying part, and only the intermediate papermaking product moves while the carrier net is fixed to each apparatus. The composition was general. Further, most of the paper products formed by this are limited to flat sheet-like products. However, in such a conventional type paper forming apparatus, since the same carrier net is repeatedly used, clogging is apt to occur, and a new carrier net is replaced each time clogging occurs, or a clogged carrier is used. It was necessary to remove the net, wash it, and then reattach it. In particular, when the paper product to be formed is a container-like product having bulkiness, clogging easily occurs at the bent portion, etc., and depending on the application, the paper product to be formed has a certain degree of mechanical strength and wet strength (water resistance). Therefore, when selecting a raw material liquid to be used, a raw material liquid having a composition that can meet these requirements is also selected. However, the raw material liquid having such a composition generally has a property of easily being clogged, and also in this respect, it has inevitably caused troublesome work such as replacement of the carrier net.

Further, when dehydrating and drying the formed intermediate papermaking product, if the intermediate papermaking product immediately after the papermaking is rapidly heated to be dehydrated, wrinkles and distortions may occur in the formed papermaking product, resulting in a commercial value. The result has been spoiled. In particular, when the paper product to be formed has a complicated shape, it is unreasonable to form the paper product into a predetermined shape at one time, and wrinkles and distortions appear remarkably in the formed paper product. This is also related to the imbalance between the required processing time in the papermaking process and the required processing time in the dehydration / drying process.

In addition to this, in the papermaking process, after a certain amount of the raw material liquid has flowed out of the papermaking cup, if the outlet of the papermaking cup is left open as it is, the intermediate product held on the carrier net located below is intermediate. The residual liquid in the papermaking cup dripped onto the papermaking product, impairing the appearance of the papermaking product, resulting in a decrease in commercial value.
