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.

S-block

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). 

Dancer

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.
