Winding system

Winding is the final step of the sheet extrusion process, however just as important as the other ones. MEAF can supply multiple winding solutions, depending on our customers wishes. One of the key factors in the choice of the winding configuration is the line speed 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

For sheet extrusion lines with higher line speeds, a buffer/accumulator with a 2 – 4 station winding system, additional rubber roll and automatic cutting system is recommended.

A buffer/accumulator is required to allow the operator to safely change the sheet onto the other winding shaft at low speed. Further on an additional rubber roller system, after the accumulator, is necessary for tensioning the sheet and automatic traversal cutting system, to ensure proper cutting of the sheet during a roll change.

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 is 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 roll diameter larger as Ø 1200 mm an additional platform is included.

  • For winding speeds up to 70 mtr/min;
  • Servo driven winder motors including winding software for a constant sheet tension;
  • Including automatic diameter calculation and sheet length calculation;
  • Including traversal cut system to automatically cut off the sheet during a roll change;
  • The buffer/accumulator, the winder and the cut system are completely automated and has a separate control system.

1 – 4 station winding system

For the sheet extrusion lines with lower line speeds, 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 sheet 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. 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 sheet 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.
