Bellmer s scope of the turn ey delivery as very detailed. It included:
■ Automatic set change ith tape applicators to fasten shipping roll tails to the roll body. ■ A traversing cutting device. ■ eb holders to maintain tension during set change. ■ ffective and reliable eb separation after the slitters, ith t o spreader rolls mounted in an ad ustable frame. ■ An automatic core feeding table and pivoting device to load ne cores bet een the drums. ■ ast and accurate automatic slitter positioning for pairs of bottom and top slitters. ■ eparation fingers after the slitting to force the ebs to separate. ■ eb feeding ith vacuum and driven belts. ■ A parent roll transporting system, B ransporter from reel to un inder. An automatic empty reel spool return system was also included.

We replaced the wire section and installed a new headbox,” says Henrik Holm.
“A key part of the conversion was, however, the new winder, which Bellmer supplied seamlessly in co-operation ith us. ellmer as e ible, as when we had an idea, they were quick to develop it. Solutions emerged smoothly,” says Holm.
CUSTOMER-FOCUSSED PRODUCT DEVELOPMENT
“Effective threading through the winder is crucial for a uff eb due to its thickness 0 m2). We improved the web threading to wind-up section by installing driven belts instead of air blows,” says Bellmer s sales manager Ahti eiponen.

livered directly to the converting plants manufacturing hygienic products; therefore, Stora Enso only needs to apply medical tape used in hospitals to bind the tails of the customer reels, instead of the typically used hot-melt glue. R&D was required to invent this medicaltape solution, which was successful, and the outcome is that 28 tape dispenser units units do the job required during the automatic set change” says eiponen.
“Occupational Safety and Healthy requirements ere fulfilled by takin the necessary measures to avoid excessive noise levels and improve ergonomics,” he adds.
Our main criteria ere that ellmer fulfilled our technical specifications and uarantees, had the right delivery time – and price, of course,” says production manager asse Aspelin.
“The targets were to reach several scheduled points, such as the start-up time, rollin test uff pulp the first time and mi in bet een uff and bale pulp. When the line was ready, we started re ular uff pulp production and periodically in bales in order to fine-tune the inder packin line,” says Aspelin.
s this as ellmer’s first modern, ne - eneration reel and winder delivery to a Scandinavian customer, the project was important to us. At the same time, we are pleased to be Stora Enso’s partner in Skutskär as a leading headbox manufacturer,” says yr i trengell, of Bellmer inland y.
