OptiReel Linear

New reel: one-level reeling on solid rails

OptiReel Linear is a completely new way to reel parent rolls. Instead of having a high structure reel spool storage and lowering arms, reel spools and parent rolls are moved on solid rails resulting in continuous and trouble-free reeling process.

OptiReel Linear provides

  • More saleable production
  • Safe and easy operation and maintenance
  • Comprehensive project execution and reliable technology
  • Lower investment and life-cycle cost

More saleable production

Getting more saleable production is a combination of number of factors. Optimal parent roll structure is achieved by accurate measurements & controls for all reeling parameters. Improved reeling quality for the critical parent roll bottom is a direct consequence from the one-level reeling. Efficient turn-up sequence, fast web break recovery sequence and optional parent roll surface binding minimize the production losses.

Capacity is also increased with OptiReel Linear due to bigger parent rolls. The parent roll size has a significant effect on overall material efficiency and capacity in the finishing area. By maximizing the diameter, it is possible to significantly improve output.

Optional center drives have proven to be excellent for preserving coated board surface and sheet properties. Since they eliminate slippage in the nip and between coated board layers during reeling, it is possible to wind large diameter rolls without scratches, gloss variations, dust or mottling. Furthermore, the possibility to use low nip load level ensures a bulkier sheet and even smoothness values in the top and bottom sets.

Coated board handled with extra care

Center driven reels have proven to be excellent for preserving coated board surface and sheet properties. Since they eliminate slippage in the nip and between coated board layers during reeling, it is possible to wind large diameter rolls without scratches, gloss variations, dust or mottling. Furthermore, the low nip load ensures a bulkier sheet and even smoothness values in the top and bottom sets.
OptiReel Linear with primary center drive is the optimal application for medium-sized production lines. It is suitable for all paper grades and particularly to applications where large parent roll diameter is required to boost the dry end capacity. Parent roll hardness is directly affected by the center drives. See figure below.

Safe and easy operation and maintenance

Low structure of OptiReel Linear enables easy access to operating and servicing positions. There are no high structures to complicate maintenance actions. Additionally, the constructions on tending and drive side are similar. Optional transfer rails for full parent rolls automate the moving of the parent rolls.

Linear reeling

For soft cover reel drums, it is important the reel drum change is fast. In conventional reeling, changing of the reel drum change might take even one day, because the primary reeling device must be dismantled. With OptiReel Linear, reel drum change takes only a few hours. There is no need to dismantle anything from primary nor secondary reeling devices.

One level reeling brings a number of safety related factors: There are no high structures, big roll masses are always frame supported, crane lifting height is smaller, there is no need to elevate spool & parent roll and all the spool and parent roll movements are well controlled.

Comprehensive project execution and reliable technology

Professional Valmet team helps you from the first steps of concept setting to services after the project phase to reach your goals. Project management, engineering, installation supervision, start-up crew and process technology managers are just some examples of the vast area of expertise.

Possibility for pilot trials is a great advantage to find just the right solution for your needs. Workshop pretesting, experienced process optimization support and proven components ensure a trouble free project.

Lower investment and life-cycle cost

The initial investment cost is lower due to simplified design (lower structure, integrated reel spool storage). Because of the design, there are less components, fewer actuators and fewer spare parts.
