Abstract: A method and apparatus for laminating flexible magnetic segments onto the plastic substrates, such as during the in-line production of shower curtains and/or curtain liners. The apparatus, which is configured for use with typical shower curtain and/or shower curtain liner producing machines, includes a substantially planar upper work surface for receiving the plastic substrate and at least one applicator unit located adjacent the work surface which automatically laminates a flexible magnetic strip and a plastic cover patch onto the curtain. Three applicator units are preferably utilized, with one such unit substantially aligned with the center of the curtain and the remaining two units being located along the longitudinal edges thereof. In operation, a thin, flexible plastic film is unwound onto an assembly table whereupon it is stopped at a predetermined position.
