04/12/2023 – Special aspects are sustainability, cost efficiency and safety
Kurre reinvent their flange-driven winder
Increasing demands as well as the needs for a sustainable design for the future have led Kurre Systems to expand its world-renowned family of flange driven winders.
The new “AB-W-1250 XL” and “AUF-W-1250 XL” models score particularly well in the areas of sustainability, cost efficiency and occupational safety. However, the decisive reason was the customers' request for higher bobbin loads.
Higher load and compact design
The previous maximum bobbin load of 1,200kg was raised accordingly up to 2,500kg. To accommodate this high load, the engineers at Kurre subsidiary Siebe Engineering GmbH specially developed a new plastic compound. Despite the high loads, a take-off speed of up to 50m/min is possible without any problems. The new winders uses bobbins with a diameter of 800mm to 1,250mm and a max. width of 930mm. The winder itself requires a footprint of just under three square meters – fully assembled.
Low budgets and constant cost pressure amongst cable manufacturers are also leading to a rethink amongst machine manufacturers. Due to improved parameters the new winder can be used much more flexible and with a cost frame of approx. 50 % of the market price of available pintle winders. It offers a cost-effective alternative.
Work safety and handling
During the redesign, special attention was also paid to occupational safety. "The previous safety concept of the flange-driven winder was detailed investigated and further developed," says Arnaldo Martins, Head of Design at the Kurre Group. Closely linked to work safety is also the handling during the individual production phases. "Only a concept that convinces the operator is a good one and will be accepted," Martins continues. To ensure this, customers were able to test the new winder during the prototype phase. The findings from these tests flowed directly into the final design. A significant new concept, for example, is the infeed and outfeed of the bobbin at floor level. The operator simply rolls the bobbin into the winder. Only rough positioning is required - the machine does the rest.
The new type of flange driven winder will find its future application in various areas such as braiding, taping and stranding lines, test rewind stands, heat treatment lines, quality assurance and cleaning. The new technology will also be used in the existing flange driven winder types in the future. With the new flange driven winder types, Kurre Systems underlines its core competence for individual machines and complete lines tailor-made to customer requirements
