ABSTRACT:
The invention apparatus comprises a duct that supplies balls to a lateral outlet tube. The outlet tube feeds laterally to a sealant applicator nozzle. An impact plunger pushes the balls successively into sealant in the applicator nozzle. The nozzle extrudes sealant containing balls as spacers, useful in bonding two flat elements, spaced apart by the balls.
