Continuous filament winding machine

The steel band is carried on a forward moving mandrel which is able to collapse and return to the beginning of the travel.

In addition to the continuous advancing band, many alternative methods of filament winding also exist.

The first winding machine for production of GRP-pipes was invented in 1965 - 1967 by Danish and Norwegian engineers: Peder Ulrik Poulsen, Tage Debess and Agnar Gilbu in cooperation between two companies, the Norwegian Vera Fabrikker (later, Flowtite Technology AS) and the Danish Drostholm Ltd.

[1][2] Peder Ulrik Poulsen invented the rotating mandrel with an endless steel band (strip) in 1967, which made the continuous filament winding process possible.

The first winder was built in Copenhagen, Denmark in 1968 and shipped to Vera Fabrikker in Sandefjord, Norway for the production of GRP-pipes.
