Embodiment 1

[0030] Please also refer to Figures 1 to 6 , a method for manufacturing a wearing article, comprising the following steps:

[0031] 1. First, add a group of rubber bands 12 between the upper non-woven fabric 10 and the lower non-woven fabric 11 for compounding to make a strip-shaped elastic sheet 101; then stretch along the flow direction MD and stretch along the flow direction The step of conveying the belt-shaped elastic sheet 101 stretched in MD along the flow direction MD.

[0032] 2. Partial elastic cutting 102 is performed on both sides of the elastic sheet 101 in the width direction CD. The cutting knife used to cut off the local elastic on the elastic sheet 101 has two blades arranged at intervals, such as image 3 The two blades shown cut out an elastic body cut-off area A on the elastic sheet 101. In the above-mentioned area A, by changing the intermittent glue application mode of the glue gun, the width W of several glue patterns in this area is changed, so as to...

Embodiment 2

[0048] Please also refer to Figures 7 to 9 , a method for manufacturing a wearing article, comprising the following steps:

[0049] 1. First, add a group of rubber bands 12 between the upper non-woven fabric 10 and the lower non-woven fabric 11 for compounding to make a strip-shaped elastic sheet 101; then stretch along the flow direction MD and stretch along the flow direction The step of conveying the belt-shaped elastic sheet 101 stretched in MD along the flow direction MD.

[0050] 2. Partial elastic cutting 102 is performed on one side of the elastic sheet 101 in the width direction CD. The cutting knife used to cut off the local elastic on the elastic sheet 101 has two blades arranged at intervals. The two blades cut out an elastic body cutting area A on the elastic sheet 101. The way of glue makes the width W of several glue patterns in this area change, so as to achieve the purpose of changing the tension in area A. Specifically, when the width W of the glue type i...

Abstract

The invention discloses an elastic waistline sheet material processing method. The processing method comprises the following steps that first, strip-shaped elastic sheet material capable of retracting along a process direction is extended along the process direction and carried along the same direction; second, tension force of the elastic sheet material is released in the process direction until the tension force is zero or smaller than the tension force of the previous step; and third, the elastic sheet material is processed and cut according to a preset length. Stretching ratio of the elastic sheet material is segmentally controlled during the conveying process, and batch process of the elastic sheet material can be realized; product pace can be greatly improved and technology process can be shortened; besides, the cut elastic sheet material is rotated and amplified and configured to an absorbing main body, so poor switch-over of the elastic sheet material among different maintaining components can be avoided; production process stability can be improved; and the waistline sheet material has a compact structure and high production efficiency.

Description

technical field [0001] The invention belongs to the field of hygienic product manufacturing, and in particular relates to a method for manufacturing an elastic waist sheet. The sheet has excellent elasticity and is provided with a waist patch, so that the prepared absorbent product is more convenient and comfortable to wear. Background technique [0002] With the development of society and the continuous improvement of people's living standards, disposable sanitary products have been widely used. At present, absorbent products containing elastic waist sheets are roughly divided into two types: diapers and pull-up pants. Existing diaper products usually add elastic parts between two layers of non-elastic sheets, and add waist stickers on the left and right sides. Since the elastic members of this product are often discontinuous from side to side or the number of elastic members is limited, this results in weaker elastic at the waistline. And although the existing pull-up pan...
