Problems solved by technology

Parts with markedly uneven elongation are the main causes of uncomfortable wearing and leakage of body fluids, etc.
[0003] However, in the existing manufacturing devices and manufacturing methods of wearing articles, there is no work to uniformize the elongation of the elastic member (for example, JP-A-8-197498 A, JP-A-8-511707 A, JP-A-8-511707 A, Table Hei 11-53060 and Special Table Hei 11-504228, etc.)

Embodiment Construction

[0020] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0021] Fig. 1(a) shows an example of the production apparatus of the present invention. The manufacturing apparatus shown in FIG.

[0022] The stretching part 1 receives the elastic member X, stretches the elastic member X by a given multiple, and sends it out. As stretcher 1, a medium speed V can be used M A belt conveyor 10 that conveys the elastic member X. at speeds lower than V M The low speed V L The elastic member X input from the upstream is accelerated by the belt conveyor 10 to the middle speed V M . Therefore, the elastic member X expands due to the speed difference.

[0023] The conveying part 2 has a plurality of pads P receiving the stretched elastic member X i And the cutter 31 which cuts this elastic member X into predetermined length. Pad P i Arranged around the drum 20, connected with the drum 20 through the pillar 11, as shown by the arrow...

Abstract

An apparatus for producing an article having an elastic member, comprises: a stretcher for receiving the elastic member at a low velocity VL and outputting the elastic member at a medium velocity VM; a carrier including a first pad and a second pad for picking up the elastic member from the stretcher, and a cutter for cutting off the elastic member while carrying the elastic member; and a station for carrying a web at a high velocity Vh and disposing the cut-off elastic member from a pad onto the web. When the elastic member striding over the first pad and the second pad is cut off, an interval between the first pad and the second pad is shortened so as to reduce a shrinking force of a portion of the elastic member between the first pad and the second pad.

Description

technical field [0001] The present invention relates to a manufacturing device and a manufacturing method of an article having an elastic member. Examples of such articles include sanitary napkins and disposable diapers and underpants. Background technique [0002] In disposable articles, elastic members are arranged on the surface of the sheet to form gathers in order to fit various parts of the wearer. The elastic members are preferably arranged on the surface of the sheet with as uniform elongation as possible. The portion where the elongation rate is significantly uneven is the main cause of wearing discomfort, body fluid leakage, and the like. [0003] However, in the existing manufacturing devices and manufacturing methods of wearing articles, there is no work to uniformize the elongation of the elastic member (for example, JP-A-8-197498 A, JP-A-8-511707 A, JP-A-8-511707 A, Table Hei 11-53060 and Special Table Hei 11-504228, etc.). [0004] Therefore, it is an obje...
