Abstract

Methods of joining members, forming molded portions with members, securing inserts with members, and joined members, such as for a frame or a frame for a fenestration unit, formed thereby, are disclosed. One embodiment of the method includes placing a first member with a first cavity in a joining position, placing a second member proximate the first cavity of the first member in the joining position, injecting a resin into the first cavity, allowing the resin to solidify at least partially to join the first member and second member to form a joined member, and removing the joined member from the joining position. Optionally, the joined member can be formed in a fixture, can include molded portions formed by the resin, and/or can include inserts held in place by the resin. Further, members without cavities can form a cavity that can receive the resin.

First claim

1 .- 3 . (canceled)

4 . A method of forming a fenestration frame comprising:
placing members of the frame in joining positions to form a continuous frame with joints between the members; the joint including a first joint and other joints; fixedly holding the members in the joining positions to form a joining assembly; orienting the joining assembly to place the first joint at an elevation below the other joints; injecting a resin into the first joint and allowing it to at least partially solidify; rotating the joining assembly until a second joint of the other joints at an elevation below the first joint and the other joints; injecting resin into the second joint and allowing the resin to at least partially solidify; repeat the rotating, injecting, and solidifying steps until all of the joints have been injected with the resin.

5 . The method of claim 4 wherein the members are fixedly held together by a belt surrounding the members.

6 . The method of claim 4 wherein the members are held together by a clamping mechanism.
