Description

Technical Field

[0001] The utility model relates to a folding device, in particular to an inner folding device for the waist of a pull-up trousers, and belongs to the technical field of pull-up trousers production. Background Art

[0002] Pull-ups are a disposable or reusable diaper alternative for infants or toddlers. They are usually designed to be like underpants, with elastic waistband and legs for easy donning and doffing. The main purpose of pull-ups is to help manage diaper use during the early childhood stage, making it easier for children to don and doff themselves, and facilitating their transition out of diapers and into adult underpants.

[0003] During the production process of pull-up pants, the waist needs to be folded inwards, and the folded part needs to be sprayed with glue before folding. However, the glue nozzle may get clogged during operation. When the glue nozzle is clogged, the machine needs to be stopped to clean the blockage before continuing production. This problem seriously affects the continuity and efficiency of the production line. Utility Model Content
