Abstract
A rotating viscometer for a paste is constructed of a rotary member, a stationary member provided in opposition to the rotary member with a small clearance therebetween, said stationary member being displaceable angularly relative to the rotary member, a paste inlet formed in communication with the small clearance to allow the paste to flow into the small clearance upon rotation of the rotary member relative to the stationary member, a paste outlet for allowing the paste to flow out of the small clearance, and a means for sensing a torque applied to the stationary member owing to the viscosity of the paste introduced in the small clearance by the rotation of the rotary member.
