Abstract
A mixing head is supplied with two or more synthetic resin components from respective supply vessels. When one of these components is highly filled and an obstruction may be expected upstream of the metering piston unit between the supply vessel and the mixing head, the recirculating line from the mixing head is connected to the duct between the supply vessel and the piston unit at a position close to a two-way valve at the piston so that recirculating flow clears any obstruction from the duct.
