Device for detecting a sufficient glue coating of a paper strip

In a method and an apparatus for controlling the physical properties of a rod of smokable material the actual values of at least two physical properties, in particular resistance to draw and hardness or deformation of the tobacco rod or of the smokable article, are detected; the differences between said actual values and predetermined desired values are determined and control signals derived therefrom; said control signals are compared with each other and the particular instantaneously largest control signal is supplied to a single actuator, that is an ecreteur or a hopper. An auto-selector circuit with maximum selection is used to compare the control signals.

Method and apparatus for controlling at least two physical properties,

A stream dryer comprises in addition to the control bypass which bypasses the heat source a second ready-use bypass which is in parallel with the control bypass and bypasses the heat source. In the event of short-duration interruptions in working, the supply of steam is interrupted and the circulation of the hot gas is maintained substantially only through the ready-use bypass, so that the temperature of the circulated hot gas substantially does not change when the relatively small heat losses due to surface and exhaust gas losses are compensated. Temperature regulation is effected through the agency of the control bypass in this state of readiness also.
