Abstract

A method for making elongated, flexible sealing bands for inner sealing of axial slots in rodless cylinders, wherein the band includes a main portion (2,12), and extending therefrom, two sealing lips (3,13) for sealing co-operation with the cylinder in areas on each side of the slot, wherein a band workpiece (1,11) is produced from a synthetic material and fed through a cutting station, wherein the sealing lips are cut (B-B, C-C) from elements (3,8,13,14) protruding from the main portion (2). The invention is distinguished by a band workpiece (1) being produced which besides the main portion and the protruding elements includes an integral strip portion (4,14) along the longitudinal extension of the band workpiece, and that, in a cutting operation (A-A), the strip portion is longitudinally cut away from the main portion after having been used for guiding and/or feeding the band at least while cutting the sealing lips (3,13). The invention also concerns a band workpiece.
