Claims21
A method of laminating a polytetrafluoroethylene liner to a flexible outer member, the method comprising:
- applying a primer to an outer surface of the polytetrafluoroethylene liner;
- applying the primer to an inner surface of the outer member, the inner surface of the outer member facing the outer surface of the polytetrafluoroethylene liner;
- annealing the primer on the outer surface and the primer on the inner surface;
- reapplying the primer to the outer surface and the inner surface;
- moving the outer surface and the inner surface into engagement with each other;
- applying a force to maintain the engagement of the outer surface with the inner surface;
- and
- annealing the reapplied primer to laminate the outer surface to the inner surface.
