The device provides for the mixture of the pastes in different proportions by varying the output of paste from the peripheral space. This variation is accomplished by holes 5 in the fixed member and holes in a member 6 which can be moved to provide varying degrees of coincidence of the holes in each member. In a modification, Fig. 2 (not shown), nozzles (10) feed the paste from the peripheral space into the main mass of paste issuing from the central tube. Again, Fig. 3 (not shown) the apertures from the peripheral space may deliver paste in the form of a jacket round the main mass issuing from the member 3 and are closable by a screw cap.
