A method for producing a chassis web for a disposable pant article, the method comprising: feeding a continuous base web in a machine direction, said continuous base web being an elastic base web and having a first side edge and a second side edge extending in said machine direction; attaching a continuous waistband component to an outer surface of said base web in an attachment area, said attachment area extending in said machine direction and being arranged between said first and second side edges of said base web and being spaced apart from at least one of said first and second side edges, wherein the waistband component is applied as a pre-fabricated elastic waistband component comprising one or more carrier webs; severing said base web and said attached waistband component by cutting along a cutting line extending through said attachment area in said machine direction thereby creating a first panel web comprising a first panel portion and a first waistband portion and a second panel web comprising a second panel portion and a second waistband portion, said first panel web and said second panel web extending in said machine direction with said first and second waistband portions facing each other in a side-by-side arrangement; shifting positions of said first panel web and said second panel web in a cross machine direction perpendicular to said machine direction, thereby bringing said first and second panel webs into an arrangement with first and second cut edges facing away from each other in said cross machine direction and with said first and second side edges facing each other in said cross machine direction; directly or indirectly connecting said first side edge of said first panel web with said second side edge of said second panel web thereby forming a coherent chassis web, while the first waistband portion is attached to an outer surface of the first panel portion and the second waistband portion is attached to an outer surface of the second panel portion.
