THE TECHNOLOGY BEHIND A “NO-TEAR”, “NO RIP” FILM CARRIAGE, AND HOW TO EXPLAIN IT TO YOUR CUSTOMERS

Wulftec's carriage

Wulftec has been providing for many years the ability to simulate the technology behind a no rip or no tear film carriage. Some of you have recently been asking about this technology. If you ever come across a customer asking about this, make sure they understand it's not revolutionary; though it was innovative when Wulftec first introduced it, we have been offering this to customers for many years. By pre-programming the load dimensions into our PLC program we can adjust the film force tension to ensure that the film will have less force around the sharp corners of the pallet. This will keep film breakage to a minimum or eliminate them completely.
An industry we sell a lot of stretch wrappers to, and that this technology works great in, is the Empty Plastic Bottle Manufactures. We can literally “lay” the film around the load to give them the coverage they need and not crush the empty containers. By knowing the load dimensions and by controlling the film force you can “tout” that your film carriage eliminates film breakage.
The negative on this, is that if the customer loads change then you need to “re-program” the dimensions. We do offer a dual laser photoeye sensor that can “measure” the load entering the wrap zone if this is an issue. Please explain to customers who ask about this feature on how it is achieved. This should help them decide if they want us to pre-program their machines.
