Abstract

A mixer is used for producing multi-component pastes at a mixing ratio other than 1:1. A deviating channel 20 is provided between the inlet opening 16 for the component of the larger volume proportion and the mixing chamber, to delay the feed of this component with respect to the other component. The presence of this deviating channel 20 causes all components to enter the mixing chamber simultaneously, thereby obtaining a paste which has the desired mixing ratio from the start.
