Strip tension regulating systems
Strip tension technique for strip processing lines
Some operational treatment of the strip – e. g. machining of complex contours or beveling – exerts excessive strip tension for save recoiling of strip with weak cross sections.
If so, an S-block and a dancer will regulate the strip tension to a tolerable level.
Thus, even thin and small strips can be machined and subsequently traverse wound or recoiled to big diameters.
The S-block either reduces the strip tension or elevates the traction during the recoiling process. The strip tension is reduced at 1⁄5 or even less.
By adding further drums, the FZ reduction or as the case may be the FZ increase is adapted correspondingly. An automatic slip control is integrated into the S-block.
When the job is to machine the edges of strips with weak cross sections or to traverse wind a strip, the use of the S-block is strongly recommended.
It is possible to machine even strips with sensitive coating as Teflon for example thanks to the extended S-block (see picture on the left side).
On the recoiler side, the dancer displaces the scope of strip tension reduction. By this means, even strips with a very weak cross section can be machined and traverse wound.
On the decoiler side, the dancer disconnects the strip tension from the coil body.
