Along with our partner, whose first winder will hit the market mid-october 2013, we had a vision. This vision was to improve the historical market leader’s winder. To do this we went back to basics and started from a clean sheet of paper.
We had three major wishes:
Decrease the cycle time
We realised early on in our internal discussions that to reduce the cycle time we would need more than 2 winding shafts per station. We also scrutinised unload and re-coring positions to reduce the time taken to unload and re-core. We believe we have found the ideal solution.
Run “stress free” thin films
Every possible roller is individually driven, all wrap angles on each roller have been considered at great length. The web path has been justified and understood by every member of the team.
Increase line speed
With thin film and increased output capacity it is necessary to run at higher line speeds to maintain a healthy extrusion output. We have developed and patented a new double bearing winding shaft arrangement, this is more stable and allows for higher critical speeds.
As we went along this journey pathway we came across many new ideas and improvements to give customers the tools to help them overcome many process difficulties that exist now and may exist in the future.
Once the concept and mechanical detail work was complete our partners and us decided to develop the control system separately, at SWP we are concentrating on a Siemens system, which we feel will be accepted better in the market
As with all our products the new stretch winder is designed for optimal performance, cost-effective operation and minimal maintenance.
Our team is an invaluable asset with a vast amount of experience in the design and supply of winders, a team enabling us to provide leading technology of process design and engineering solutions.
