Abstract
This invention relates to a process and apparatus for the manufacture of viscose products which includes a motor means having a constant torque in the viscose during ripening wherein the resistance on said motor means changes as the viscose ripens because of the change in viscosity and the temperature is adjusted in response to said change in viscosity to heat or cool the viscose, and thereby control its rate of aging.
