Method for manufacturing profiles for extensible door or window frames

摘要

The method involves forming two similar pieces on an edge of an adhesive layer by machining process, and providing a transversal piece by a line of process. A formed piece is provided and integrated as a connection element on sized edges of the similar pieces. An esthetic cover sheet is integrated on a U-shaped profile, so as to form a cut with respect to the U-shaped profile by a transverse branch. Two L-shaped profiles are provided and used for covering sides of structural expanding frames, where L-shaped profiles are used as an L-shaped lateral profile (3).
