Problems solved by technology

[0007] However, in the above-mentioned prior art, since the ridges are arranged in the recesses, when the continuous body of the absorber is taken out from the recesses and transferred to the next conveying mechanism, it is easy to cause the continuum to catch on the ridges and cause continuous body damage problem

Embodiment

[0031] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0032] The absorptive core manufactured by this manufacturing apparatus is used as the core of an incontinence pad etc. besides disposable pants and a diaper, for example, and has an hourglass shape, for example.

[0033] Such as figure 1 As shown, this manufacturing apparatus includes a supply device 1 , a fiber laminating cylinder 2 , a conveyor belt 4 , a cutter 5 , and an anvil 6 .

[0034] The supply device 1 includes a dome-shaped housing 10 and a defibrating machine 11 . The defibrator 11 defibrates (pulverizes) the pulp supplied from the upstream into a fibrous form to generate fluff pulp (fiber). The fluff pulp fills the housing 10 and is laminated on the fiber lamination drum 2 by setting the inside of the fiber lamination drum 2 to a negative pressure. Such defibration and fiber lamination are known techniques, and are disclosed in, for example, Patent D...

Abstract

The present invention is provided with a supply device (1) for supplying pulverized fiber, and a fiber-accumulating drum (2) for continuously accumulating fiber on the external peripheral surface (2f) in a predetermined fiber-accumulating concavity (30) while the fiber supplied by the supply device (1) is suctioned from the external peripheral surface (2f) toward the inner side. The drum (2) is provided with: a mesh member (32) for allowing air to pass and for catching fiber; a mold plate (31) disposed on the external peripheral surface side of the mesh member (32) and used for forming a concave part (30); and a blocking member (34) for blocking fiber from being suctioned so that the amount of fiber to be accumulated is reduced between mutually continuous absorbent cores (C). The blocking member (34) is disposed on the internal peripheral surface side (32f) of the mesh member (32).

Description

technical field [0001] The present invention relates to a method of manufacturing an absorbent core of a disposable wearing article. Background technique [0002] As a method of producing such an absorbent core, generally, pulverized fibers are adsorbed to fiber-stacking recesses continuously formed on the outer periphery of a fiber-stacking cylinder to form a continuous body of the absorbent body. [0003] In Patent Document 1 described below, the fiber lamination recesses are provided with ridges traversing the recesses in the width direction at predetermined pitches, and thin-walled portions are formed on the continuum at predetermined pitches. This makes it easy to cut the continuum at the thin portion. [0004] prior art literature [0005] patent documents [0006] Patent Document 1: JP2009-112438A (Fig. 6) [0007] However, in the above-mentioned prior art, since the ridges are arranged in the recesses, when the continuous body of the absorber is taken out from th...
