A method of making an undergarment (1) having side seams (7, 9) from a two-dimensional preform comprises the steps of cutting a cotinuous web (50) along transverse cut lines (76, 76') to form individual preforms (17), cutting each preform (17) along a leg contour (55, 56) extending along each longitudinal side (27, 29) of the preform (17) in the region of a central section (40, 40'), wherein each leg contour (55, 56) does not touch the respective longitudinal side (27, 29), thus forming two gripping flaps (53, 54),gripping the preform (17) at the gripping flaps (53, 54), pulling the gripping flaps (53, 54) outwardly away from the longitudinal sides (27, 29) such that the preform (17) is doubled over along a transverse centerline (16) and such that sealing areas (43, 45) in the region of back waist sections (39, 39') are placed in a superimposed relationship with sealing areas (47, 49) in the region of front waist sections (41, 41'), and mutually connecting the sealing areas (43, 45, 47, 49).
