There is usually clear potential for improving production efficiency and line capacity in the finishing area. By letting Valmet help you in selecting the right reel for your grade, machine speed and web width, you can make full use of this potential. Valmet provides all paper and boardmakers with a wide range of reels to match their specific needs and various reeling challenges.
Reeling process becomes more demanding if the operating speed and reeling width are high, parent roll diameter is big and/or the paper or board grade requires more sensitive reeling. With the level of difficulty in reeling in mind, the reel types can be divided into two groups. Depending on the reeling process conditions, there are either reels without center drives or reels with center drives.
Reels without center drives are ideal for reeling required by grades and operations with less demanding reeling conditions. Reels with primary or primary and secondary center drives are aimed at the more challenging grades and high-speed production lines typically with online calendering and/or coating.
Reeling and winding are the two steps in the boardmaking process where the bulk of produced board can be either preserved or ruined. Nip loads that are too high are the main reasons for losing bulk. Valmet’s combination of bulk-saving reeling and winding are essential for e.g. coated board makers.
Valmet's center-driven reels – precise load control and use of center drives minimize bulk loss and the uniques OptiWin Belt – the ultimate winder for FBB, nip loads are less than 50% compared to a two-drum winder.
The total bulk saving potential is up to 4% with a combination of OptiReel center-driven reeling and OptiWin Belt winding.
