  • the invention relates to a method and
  • Plastic-coated fabric consisting of a seat cover made by sewing is filled with a foam that expands within the cover and firmly bonds with the coating of the fabric.
  • thermoplastic masking tape as it is proposed in principle by DE-PS 821 843.
  • the masking tape is fed continuously, heated together with the coating of the fabric and pressed with the help of pressure rollers on both sides of the seam overhang, whereby it firmly connects to the coating and the thread seam
  • Ah cover tape is always welded in the same orientation to the thread seam. This requirement is not met if the masking tape is even
