DSR FL with an integrated front loading unwind

The DSR FL (Front loading) slitter rewinder offers a compact solution for smaller unwind and rewind diameters. The arrangement of unwind and rewind sections on the same side permits excellent access, visibility and user comfort. The need for operator movement is also limited and web threading more convenient than conventional two side machines.
