Abstract
In a process for bonding two substantially flat elements, a highly viscous sealant containing balls as spacers is applied to a first element in a thickness at least corresponding to the desired distance from the second element and the latter is engaged and pressed onto the first element. The balls (6) are successively added to the sealant in an applicator nozzle (2) prior to the application of the sealant. This process can be performed with an apparatus having an applicator nozzle (2) for the supply and application of the sealant (4) and a ball supply device (10). The latter contains a supply duct (12) for supplying the balls (6), an outlet tube (14) connected at an angle to supply duct (12) and issues via an opening (16) laterally into the applicator nozzle (2) and an impact plunger (18), which is movable by the end remote from applicator nozzle (2) into the outlet tube (14).
