Embodiment Construction

[0021] Such as figure 1 and figure 2 As shown, the papermaking equipment of an embodiment provided by the present invention is used for making tissue paper. The papermaking plant comprises a forming section 10 , a wet transfer section 20 and a drying section 30 .

[0022] The forming section 10 includes a series of guide rolls 12 and a fabric 14 moving around the guide rolls 12 , and a headbox 16 . The fabric 14 forms an endless loop. A suspension of raw fibers for papermaking is cast via a headbox 16 onto a fabric 14 and forms a paper web 11 on the moving fabric 14 . The web 11 is brought to the junction of the forming section 10 and the wet transfer section 20 by the movement of the fabric 14 and transferred to the wet transfer section 20 .

[0023] figure 1 Only one headbox 16 is shown in , it can be understood that more can be set in actual production. Moreover, existing other types of molding units 10 can be used for the molding and papermaking of household paper i...

Abstract

A papermaking device comprises a forming portion, a wet transfer portion and a drying portion, wherein the forming portion is used for forming the papermaking raw materials into paper webs, the wet transfer portion is used for transferring the formed paper webs to the drying portion for drying, an airflow generation box is arranged on the wet transfer portion, the surface of the airflow generation box, which faces the paper webs, is provided with holes, the airflow generation box is used for jetting airflow to the paper webs through the holes and forming patterns on surfaces of the paper webs, and the patterns are used for replacing embossed patterns formed in an embossing process after the paper webs are dried. The invention further provides a papermaking method. Tissue paper manufactured through the papermaking device and the papermaking method can form the patterns similar to the embossed patterns in front part of papermaking, so that the rear part embossing working procedure can be omitted, and the papermaking process can be shortened.

Description

technical field [0001] The invention relates to a papermaking device and a papermaking method, in particular to a papermaking device capable of forming patterns similar to embossing and a corresponding papermaking method. Background technique [0002] Household paper is widely used in daily life, such as facial tissue, toilet paper, wiping paper, etc. are well known to the public. Usually, in order to improve certain physical properties of tissue paper, such as bulkiness, water absorption, etc., and to increase the aesthetics of tissue paper, certain processes are used to form concave-convex patterns or patterns on the surface of tissue paper. Thereby enhancing the added value of household paper. [0003] At present, the process of forming patterns on the surface of household paper is mainly to emboss the paper in the post-processing section. The embossing process in the processing section usually makes the paper pass through the embossing nip formed by two rollers to achi...
