<p>The invention relates to Method of making an undergarment (1) having side seams (7, 9) from a two dimensional preform (17), the preform (17) comprising: two longitudinal sides, (27, 29) each longitudinal side having a central section (40, 40'), a front waist section (41, 41') and a back waist section (39, 39'), two transverse sides (31, 33), a transverse centerline (16) located midway between the transverse sides (31, 33), and four sealing areas (43, 45, 47, 49) located in the region of the front and the back waist sections (41, 41', 39, 39'), the method comprising the steps of cutting a continuous web (50) along transverse cut lines (76, 76') to form individual preforms, cutting each preform (17) along a leg contour (55, 56) extending along each longitudinal side (27, 29) in the region of the 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 the transverse centerline (16) and such that the sealing areas (43, 45) in the region of the back waist sections (39, 39') are placed in a superimposed relationship with the sealing areas (47, 49) in the region of the front waist sections (41, 41'), and mutually connecting the sealing areas. By cutting the leg contours partially through the preform, accurate control of the waist edges in maintained during the seaming step, which is especially advantageous when active stretch material is applied along the waist. <IMAGE></p> |
