Abstract
Described herein is an apparatus for dynamic metering of sealant volumes, and also described herein is a corresponding method.The apparatus of the invention includes two containers for sealant components; a first drive, which is connected to two devices, each of which is able to convey one of the sealant components from its container; a drive controller; a mixing unit for mixing the sealant components conveyed from the containers, having an opening for applying the sealant to a component; and also, additionally, a compensating container with a compensating volume; and a second drive, which is connected to a piston which reaches into the compensating volume of the compensating container.The compensating container in this arrangement is connected to the mixing unit. The first drive and the second drive can be dynamically controlled jointly by the drive controller.
