- Function drawing
Chain-type stretcher systems monitor and control the fabric tension of revolving dry wires. Integrated tension sensors acquire the fabric tension continuously and without delay. A digital three-point controller continuously compares the actual value with the set target value and sends a correction value to the actuating drive as necessary. The tension on the dry wire is increased or decreased via the chain-type stretcher.
Area of use
The chain-type stretcher system is used in the dryer section of a paper machine.
Chain-type stretcher systems can be freely mounted in terms of position. Wrapping of 180° is desirable for the stretch roller. The adjusting plane of the chain-type stretcher should be positioned in the bisecting line between the infeed and outfeed. Wrap angle compensation needs to be incorporated if the overall wrap around the stretch roll is greater than 150°.
