摘要： 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).

摘要： 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.

摘要： In a method for the production of a sealing and adhesive strip, particularly for the direct glazing of motor vheicles, using a moisture-hardening single-component polyurethane composition based on telechelic isocyanate prepolymers of aromatic diisocyanates in stoichiometric excess and polyols a composition is employed comprising a) a catalyst for the moisture-hardening and b) a blocked activatable cross-linking agent, and a solvent or solvent mixture is continually injected into the inside of the strip during the extrusion of the strip which liberate the cross-linking agent.For the implementation of the method an extrusion nozzle for the sealing and adhesive strip is used which comprises an injection needle for the solvent opening into the nozzle, the exit opening of which points in the extrusion direction and is located in the region of the center axis of the extrusion die forming the strip.
