Abstract

Machine frames and other structures can be assembled from rod or tubular elements cemented into joining fittings described in the IBM Technical Disclosure Bulletin, Vol. 11, Pages 760-761. In order to provide a reliable joint and neat appearance, as well as to save material, it is desirable that a precisely metered, even coat of adhesive be applied to the parts to be joined, before assembly.

Structural Adhesive Applicator

Machine frames and other structures can be assembled from rod or tubular elements cemented into joining fittings described in the IBM Technical Disclosure Bulletin, Vol. 11, Pages 760-761. In order to provide a reliable joint and neat appearance, as well as to save material, it is desirable that a precisely metered, even coat of adhesive be applied to the parts to be joined, before assembly.

Epoxy cement can be applied to the frame members and corner members in this manner by extruding nozzles dimensioned to conform to the parts. For coating the interior of a fitting, the extruding nozzle comprises body 10 with bearing edge 12 having a slip fit with inner surface 14. Mounted within body 10 is nozzle plug 16 with flared portion 18 defining annular orifice 20. Body 10 is mounted on pipe 22 which connects to a source, not shown, of epoxy cement under pressure and conduct the cement to body 10. It flows through the interior of body 10 to orifice 20. Edge 24 of plug 16 has the same shape as bearing edge 12 of body 10 but is dimensioned to be smaller than the latter by the thickness of the adhesive coat to be applied. Alternatively, this same clearance can be applied at edge 12 and an exterior arrangement car be provided to support the workpiece.

An external nozzle can be provided for applying coating to the exterior surface of rod or tube elements. This nozzle consists of housing 10' having nozzle plug 16' mounted in such manner as to pr...
