Method of providing resin free surfaces adjacent a bonded joint
First Claim
1. A method of resin bonding opposing surfaces of a pair of members for providing a joint having substantially resin free surfaces adjacent said joint, comprising the steps of:
- covering in intimate physical contact said adjacent surfaces and said joint with a thin, perforated, flexible, and nonadherent film for perforating resin extruded from said joint during application of bonding pressure;
covering said nonadherent film with a sheet of flexible absorbent material for absorbing the resin perforated through perforations along said film;
applying bonding pressure tending to extrude said resin from said joint; and
removing said nonadherent film and said absorbent sheet from said surfaces adjacent to said joint.

Abstract
A method of resin bonding opposing surfaces of a pair of members for providing a joint having substantially resin free surfaces adjacent the joint. The adjacent surfaces and the joint are covered in intimate contact with a thin, perforated, flexible, and nonadherent film for perforating resin extruded from the joint during application of bonding pressure. The nonadherent film is covered with a sheet of flexible absorbent material for absorbing the resin perforated through perforations along the film. Bonding pressure is applied to the joint to extrude the resin from the joint. The nonadherent film and the absorbent sheet is then removed from the surfaces adjacent to the joint to facilitate secondary bonding to the adjacent surfaces.
