Abstract
A method for forming an undergarment comprises cutting a web to form a pre-form comprising transverse edges and two longitudinal edges, each longitudinal edge having two waist sections and a crotch section located intermediate the waist sections, a sealing area located adjacent and inboard of each waist section, and transferring the pre-form to a processing wheel. The method further comprises gripping the pre-form adjacent each waist section with grippers in four gripping areas, each gripping area located near a respective sealing area, jointly rotating the grippers that hold the gripping areas in the region of one of the transverse edges around at least one hinging axis to place the transverse edge generally parallel and opposite to the second transverse edge, superimposing the sealing areas in a contacting relationship, joining the superimposed sealing areas, thus forming the undergarment, and releasing the undergarment from the grippers.
