Embodiment Construction

[0012] The details of the method for manufacturing disposable diapers according to the present invention can be better understood from the following description with reference to the accompanying drawings.

[0013] attached figure 1 It is a partially broken top view showing an open type disposable diaper 1 according to the present invention. The diaper 1 generally comprises a bodily fluid absorbing member 2 which is rectangular and slightly elongated in the longitudinal direction of the diaper 1, and an hourglass-shaped sheet-like support member 3 . Viewed in the longitudinal direction, the diaper 1 structurally comprises a front waist region 6 , a rear waist region 7 and a crotch region 8 extending between the two waist regions 6 , 7 . The size of the diaper 1 in the longitudinal direction is divided in half by the center line N-N.

[0014] The support member 3 comprises an inner panel 4 facing the wearer's body and an outer panel 5 facing the wearer's undergarment, the inn...

Abstract

A continuous first web (351) moving in a first machine direction (A) to obtain an absorptive member (302) for a disposable diaper has its outer surface coated with a hot melt adhesive agent (354), and then it is guided into between an upper cutter roll (361) and a lower cutter roll (362) and cut, thus forming an individual absorptive member (302). With the adhesive agent(354) pressed against the peripheral surface of a guide roll (363), the absorptive member (302) is guided into between the lower cutter roll (362) and the guide roll (363), and then transferred to an angle conversion roll (364). After the absorptive member (302) has changed its direction on the angle conversion roll (364), it is joined to a second web (352) moving in a second machine direction, through the adhesive agent (354). Preferably, the upper and lower cutter rolls (361, 362) have a diameter smaller than that of the angle conversion roll (364).

Description

technical field [0001] The present invention relates to a method for manufacturing disposable diapers. Background technique [0002] Japanese Patent Application Laid-Open No. 1992-161152A discloses a method for manufacturing absorbent articles such as disposable diapers. According to the method disclosed in this publication, a web is coated with a layer of adhesive on one surface, and then the web is guided between a roller as a cutting device and a roller as a redirecting device and Cut to obtain individual absorbent bodies, the web is a series of individual absorbent bodies and extends in one machine direction. The individual absorbent bodies are continuously rotated 90° about their own axis from the machine direction to a transverse direction perpendicular to the machine direction on the reorientation device and then attached to the outermost sheet supplied along the machine direction so that the The individual absorbent bodies are spaced along the machine direction ont...
