Winding system

Winding is the last step into the sheet extrusion line but a good reliable winding system is just as important as the other modules in the sheet extrusion line. Meaf can supply multiple solutions which can be chosen according to the customers wishes. One of the key factors in the choice of the winding configuration is the linespeed of the sheet extrusion line. Other factors might encompass multiple lane winding or space availability. The following configurations are available: 2 – 4 station winding system with platform For the larger sheet extrusion lines with higher line speeds, a buffer/accumulator with a 2 – 4 station winding system with platform, rubber roll and automatic cutting system is recommended. A buffer/accumulator is required to allow the operator to properly change the rolls without the sheet making contact with the floor. Further on an additional rubber roller system (mounted on the platform) after the accumulator is necessary for tensioning the sheet and automatic traversal cutting system. Meaf can deliver a system with 2, 3 or 4 A-frames who are mounted on wheels and positioned by means of a guiding rails mounted on the floor. Included are 1 pneumatic expansion winding shaft with Ø 3″ or Ø 6″ for each A-frame. The winding system comes with one lift truck to pull the A-frames away.
 
  • For winding speeds up to 53 or 70 mtr/min
  • Servo driven winder motors including winding software for a constant tension
  • Including automatic diameter calculation and sheet length calculation.
  • Including traversal cut system which is a tool to automatically cut off the sheet during a roll change.
  • The buffer/accumulator, the winder and the cut system are completely automized in the control system.
1 – 4 station winding system For the smaller sheet extrusion lines with lower line speed, the winding system without extra platform, rubber roll and automatic cutting system is the best choice. Depending on the requirements, Meaf can deliver a system with 1, 2, 3 or 4 A-frames who are mounted on wheels and positioned by means of a guiding rails mounted on the floor. Included are 1 pneumatic expansion winding shaft with Ø 3″ or Ø 6″ for each A-frame. The winding system comes with one lift truck to pull the A-frames away.
 
  • For winding speeds up to 25 mtr/min
  • Servo driven winder motors including winding software for a constant tension.
  • Including automatic diameter calculation and sheet length calculation.
2 – 4 station revolver turret winder Why choose a turret? Turret winders offer substantial productivity gains by increasing run time, especially on high-volume orders where many repetitive cycles make minimizing downtime between cycles critical. The basic turret design helps reduce downtime, and specialized features as automatic sheet cutting further contribute to improved productivity and cost savings. These machines are ideal for applications with small to medium finished roll diameters.
 
  • For winding speeds up to 40 mtr/min
  • Servo driven winder motors including winding software for a constant tension
  • Compact design
  • Including automatic diameter calculation and sheet length calculation.
  • Fully automatic winding on 2 or 4-cores simultaneously.
  • Easy operation by touch-screen operator panel.
  • Safety functions as pressure-sensitive walking areas, light curtains and sheet-tension reduction while changing rolls.
  • Can be used with or without accumulator.
