FUNCTION
In production processes with moving webs, there is typically an unwinding station at the machine infeed and a rewinding station at the outfeed. During unwinding, the winding station is moved via a linear drive to feed the web in the desired position. On the other hand, during rewinding, the winding station follows the constantly changing web position via a linear drive to achieve an evenly wound reel.
AREA OF USE
The ELWINDER web guiding system with winding stations is always used if it is not possible to use a pivoting frame or steering rollers due to lack of space.
APPLICATION
During unwinding with ELWINDER web guiding systems, the sensor is mounted on the machine to define the target web position. The position detection system should be located as close to the final winding station guide roller as possible. During rewinding, the sensor is fastened to the winding station to set the target position of the winding station for the controller. Here, the position detection system should be located as close to the final machine guide roller as possible. The guiding path L1 depends on the elasticity of the web. The larger the transverse elasticity range, the shorter the path L1 can be. Experience has shown that the guiding path should be the equivalent of half a web width.
