ABSTRACT:
A continuous method of providing a gasket to a reclosable fastener strip having reclosable closure strips with interlocking profiles. The fastener strip is moved longitudinally, the profiles are disengaged and the closure strips are separated by approximately 90.degree. from one another. A membrane is conveyed, independently of the fastener strip, along a path that brings it parallel to one of the closure strips. Thereafter, the separated closure strips are brought back together to sandwich the membrane between their respective profiles and the profiles are re-engaged.
