Joint between the ends of prefabricated spacers for insulating glass, and process for producing said joint

摘要

A diffusion-tight joint (30) between ends of prefabricated spacers (10) that support a diffusion barrier (3) on the spacer outer face is achieved in that a tongue (9) is formed from the diffusion barrier (3) at an end of two spacers (10) that abut each other at a joint (30), the tongue protruding over the end. The tongue (9) is fixed to the outer face of the diffusion barrier (3) of the other end of the spacer (10) using an adhesive application (13) so that an overlapping of the diffusion barriers (3) of both ends is achieved. The formation of the joint can be formed in the corner region of prefabricated spacer frames (10) or in straight regions of spacers (10), thus wherever ends of spacers (10) that are prefabricated abut each other.

主权项

1. A system, comprising:
a joint; and a plurality of prefabricated spacers for a plurality of insulating glass plates, the joint being disposed between ends of abutting ones of the prefabricated spacers, the spacers having a diffusion barrier that is a metal strip on an outer side facing toward the joint disposed between the glass plates, a protruding tongue being integral with and protruding from the diffusion barrier on one end of a first one of the abutting spacers the protruding tongue being bonded to an outside of the diffusion barrier at one end of another one of the abutting spacers.
