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

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.

[ Having thus described the invention, what is claimed is:] [1.] A process for the continuous forming of a bag closure with a gasket comprising the steps of:(a) moving two closure strips with engaged interlocking profiles in a longitudinal direction of the engaged strips;(b) disengaging the profiles from one another;(c) at a point along the path of the closure strips, beginning to separate the two closure strips;(d) conveying a membrane independently of the closure strips, between said profiles at a position along the path of the closure strips downstream of said point and then along a path substantially parallel to one of the separated closure strips;(e) bringing the separated strips together and re-engaging the disengaged profiles with the membrane between the profiles.
