Abstract
The treatment device includes a container for a treatment fluid, in which a drum around which the web loops rotates eccentrically. The drum is made up of axis-parallel, hollow, sealed rods and possesses a drum shaft structured as a hollow shaft, which together produce a buoyancy which makes up a significant part of the weight of the drum and the drum shaft. The drum is suspended at one end via stretchably elastic drive belts, and at the other end on tension springs, which catch the remaining weight. The drum shaft is eccentrically mounted on an eccentric shaft. The eccentric shaft is provided with equalization weights. All of the measures act together to allow low-vibration operation, towards the outside, of the treatment device.
Claims10
A treatment device for treating a continuously moving web, comprising:
- a machine frame;
- a container supported in the machine frame, to hold a treatment fluid;
- a drum rotatably located within the container, so that it is largely immersed in the treatment fluid, the drum having a cylindrical, fluid-permeable circumference, at the bottom of which the web rests against a region of the drum which is immersed in treatment fluid, the web wrapping about the drum with a looping angle of at least 270°;
- a driven eccentric shaft which is hollow and rotationally mounted in fixed external bearings;
- a drum shaft having a first end and a second end, that carries the drum, eccentrically mounted on the eccentric shaft, and which surrounds the eccentric shaft, the drum shaft being rotationally mounted at its ends on regions of the eccentric shaft that are eccentric to the axis of rotation of the eccentric shaft;
- wherein the drum shaft is supported on the machine frame at both ends, in elastically resilient manner, in a plane perpendicular to its axis.
