Mark Evans from Kenray. Today’s short blog is talking a little bit about some of the common problems experienced with front drive belt formers.

Here, you can see a typical former that’s been returned for some refurbishment work.

Typically, you’ll see burn marks on the center of the PTFE strip. Either side of the PTFE strip you’ll see grooves that have been warn by the drive belts.

Here you can see the comparison between the old and the new PTFE strip.

We recommend you change these frequently as the uneven surface will compromise the back seal.

We would also recommend that when you change the PTFE strip, you change the drive belts at the same time. At Kenray,

we’ve developed many variants of the TNA back seal to ensure, proper sealing, particularly with Matt and paper film.

In the example, shown the PTFE is replaced by stainless steel, which also assists in keeping the tube stable.

The insert in the center can be replaced with different materials to seal different films.
So there you have a short video on front-drive belt formers. I hope you found that useful. If you need more information, please either visit our website or give us a call on +44 (0)1530 400 100 or email perform@kenrayglobal.com
