Elastic waistline with multiple groups of elasticity, and manufacturing equipment and manufacturing method thereof

Abstract

The invention discloses an elastic waistline with multiple groups of elasticity, and manufacturing equipment and a manufacturing method thereof. The elastic waistline comprises a wrapping layer and spandex filaments arranged in the wrapping layer, wherein the wrapping layer comprises a first region, a second region and a third region; the spandex filaments comprises a first spandex filament, a second spandex filament and a third spandex filament; multiple groups of spandex filaments are transmitted through multiple groups of servo motors of multi-filament uncoiling equipment, and is subjectedto transmission and glue spraying through a speed sensor and a wire guide roller; transmission equipment transmits the wrapping layer, and glue spraying is performed on the wrapping layer; the wrapping layer is turned and folded by a cloth folding plate, and the spandex filaments are wrapped; the wrapping layer for wrapping the spandex filaments is pressed by a pressing roller group. The elastic spandex filaments are uniformly distributed in each region, so that the plane of the elastic waistline is very flat; the use comfort of users is improved. In the production process, intermittent glue spraying is performed, so that the glue spraying quantity is reduced. The multi-filament uncoiling equipment is provided a plurality of servo motors for singly transmitting a plurality of spandex filaments; the occurrence of a disturb problem is avoided.

Description

technical field

[0001] The invention relates to an elastic waistline with multiple sets of elasticity, its manufacturing equipment and manufacturing method. Background technique

[0002] Applied to the elastic waist of pull-up pants and ring-waist diapers, which can be stretched or shrunk by the elasticity of spandex yarn to fit the user. However, in the prior art, after the elastic waist is compounded with spandex yarn, the elastic waist The surface is uneven and wrinkled, which affects the fit with the user and the comfort of use. During the production process, the spandex yarn is transported into the wrapping layer and compounded by spraying glue, and the glue is sprayed directly in the wrapping layer. , the amount of glue sprayed is large, which affects the comfort of the elastic waist. Secondly, when the spandex yarn is not transported and arranged in the production process, it is easy to disturb and dislocate the spandex yarn. Contents of the invention
