Abstract:
A method for producing a chassis web for a disposable pant article, the method including feeding a first continuous base web in a machine direction; attaching a continuous elastic waistband component to the first base web in an attachment area extending in the machine direction; attaching a second continuous base web to the first continuous base web and the continuous waistband component, covering at least the continuous waistband component, thereby forming a compound base web having first and second side edges, the attachment area being spaced apart from at least one of the first and second side edges of the compound base web; severing the compound base web and the attached waistband component by cutting; shifting positions of the first panel web and the second panel web in a cross machine direction; forming a coherent chassis web.
