Apparatus and Method for Manufacturing Absorbent Body Associated With

Absorbent Article Full Description BACKGROUND The present invention relates to an apparatus and method for manufacturing an absorbent body bonded to an absorbent product; as a non-reusable diaper. For example; The non-reusable diaper includes an absorbent body that absorbs the aforementioned liquid. The absorbent body contains a settling body in which the liquid absorbent material is precipitated in a certain shape; Saag Representation of the liquid absorbent material with Mannam fiber core and granular super absorbent polymer to retain the shape of the deposited object and to prevent its rupture when wearing the absorbent product; The deposited body 3 passes between a pair of upper and lower pressure rolls 41a' and 1lgp' 0 rounds as shown in Figure 1a. Protrusions 42' are normally located on the pressure cylinder 41 - one of the former pressure rollers - fitted on its outer circumferential surface 41 q'. Accordingly; Protrusions are formed on the deposited body 3. In the patent ol the pattern of intaglio formation is represented by the rhombic lattice pattern. List 1 of citations: patent f for invention 1 [Unexamined Japanese Patent Application Publication No. 5 2011-115245 . General description of the invention The diamond-shaped mesh pattern is formed by a press roll 14 with projections 5 42' forming networks in the shape of a diamond on the outer peripheral surface 41' Jie" Figure 1b A diagram showing the projections 42' forming networks on Certain form; It is an advanced view in which the peripheral surface 41 s” of the pressure cylinder 41 extends over a plane. As shown in the form (al

The 42' protrusions forming the rhombic lattices are formed by joining a group of linear projections 06-5508660 42p; And 42 p'... at the inner sections c p 42 p. Among the de gens are linear protrusions Fig. 42p; 42 p....; The linear protrusions 42p' and 42g' adjacent to each other along the axis of rotation C41 of the pressure cylinder 41 (hereinafter referred to as direction AA) - 5 opposite each other - are inclined to the direction of rotation D41A. Accordingly; This pair of protrusions 2p»42p serves to segment the rhombic regions A42p' and A42p on the outer peripheral surface 41q » of the pressure cylinder 41a. Each rhombic region A42a contains a portion of a42au' dotted in the shape of [co] where there is ea a42au' in the preceding half of the rhombus A42a. The volume of the previous half a42p' is reduced in the a y direction opposite to 0 direction of rotation of the deg A41' of the pressure cylinder 141) and the half of 1817 a42p' is a gia tapered region part a42p'. In the case of These linearly shaped contiguous 42r and 42r' protrusions segment the tapered-end region gia a42r Cob in the reverse direction; when the pressure roller [14] compresses the deposited body 3; a solid part referred to as the solid spot is formed; locally; in the deposited body 3. This may cause several problems 5. The following are the reasons for the formation of this solid spot: First, we assume that the outer circumferential surface 41 q “as shown in Figure 1 [b] of the pressure cylinder 41 includes parts of the area A 42 gg’ with a tapering end in the reverse direction In this case, as shown in figure [of] the deposited bodies 3 move in the direction of transport through the disk g41 ' between a pair of rotating pressure dolphins 1+ja' and 1lg'.During this movement, the parts of the sorbent material Jah are compressed each precipitator 3 to flow in reverse rotational direction of DJA41' pressure cylinder 41A; As indicated by the arrows in Fig. 1c. Accordingly; In the tapered area part A42U' the air and liquid sorbent accumulates in the fine terminal section 5 A42U' located on the anterior side. In the case of a high rate of distribution of the sorbent

For air and liquid » A part of the precipitated body 3 corresponding to the tapered terminal section 421 p u ' is compressed by protrusions 42 p '. so; The air pressure rises and the density of the absorbent material increases. for these reasons; The part becomes stiffer than the other parts. Accordingly; A solid spot forms. The hard patch may cause the wearer to feel uncomfortable and thus prevent the liquid from being absorbed. This invention has been prepared with the aforementioned problems in mind; its benefits are to prevent stain formation

The solid that may form when the precipitated body in contact with an absorbent product is compressed. Solution to the problem: One of the aspects of the invention to achieve the aforementioned feature is the manufacture of a device for manufacturing an absorbent body connected to a product (ake).

0 The precipitated body consists of a precipitated liquid absorbent material; of the following: A pair of rotating components that rotate so that they feed the precipitated body toward the Jil direction while inserting it between the outer peripheral surfaces of the rotating component pair in a compact manner A pair of rotating components is fed into the deposited body along the (Jal) direction A y direction is determined by the spindles of rotating components; And

5 Provide a series of linear projections protruding from the outer circumferential surface of at least one pair of rotating components; Among the linear shaped “Ban” ridges is a pair of adjacent bulges in the direction of the A-R region on the outer circumferential surface; The segmented region is interpolated in the a-y direction;

0 The segmented region includes ela a tapered region gia is smaller in size gia the tapered region in the y direction as it extends opposite to the direction of rotation of the rotating components 3
