ABSTRACT:
A corrugator paste or adhesive manufacturing system provides a viscosity testing tank which is separate from other tanks used in the system. Separate storage tanks are provided for storing each of a plurality of different pastes or adhesives. A closed loop system or network of pipes circulates paste or adhesive from a mixing tank or tanks and from each of the storage tanks through a viscosity monitoring station, and then back to the storage tanks after a viscosity test is performed in the testing tank. An electronic control circuit allocates a time for giving each tank access to the viscosity monitoring station and for comparing the measurements during each such time with a pre-stored criterion for the paste or adhesive that is then being measured. If the viscosity read at the monitoring station corresponds to the stored criterion, the adhesive is returned to its proper storage tank. If there is no such correspondence, various controls may be automatically operated to correct the composition of the paste or adhesive. If the viscosity reading indicates that the adhesive is hopeless, suitable valves are operated to dump an entire batch of said adhesive.
