Cutters and Stackers
For the winding of extruded and cooled film one or more Single Station Winders can be selected, which is a good and cost-effective solution especially for big film rolls. We offer Single Station Winders for maximum roll diameters of 400 to 1500 mm with expansion winding shafts mounted overhung or on both sides for outside diameters 3’’ and 6’’.
For ideal winding conditions we construct and build Turret Winders with synchronous servo geared motors. They are exactly tuned to the mass inertia and can be synchronized to one leading drive. The top of the film can be wound to the inside or outside. esde Turret Winders are suitable for film thicknesses between 0,1 – 2,0 mm and a maximum web speed of 40 m/min.
At the Automatic Cross Cutting Unit the „flying knife“ immerges into the film web as the full roll is rotated into position. The control for the cutting process is coupled to a length counter. The finished film rolls are manually removed. The automatic cut is carried out up to a film thickness of 0,7 mm.
The Turret Winding System can also be built as Double Winder for two film webs. Upstream a Film Accumulator with a capacity of 20 meters can be installed for easy and safe roll changes in the winding area.
For custom-fit dimensioning of sheets we provide our Cross-Cutting Shears. The cutting length pre-selection of the sheets and their number are set on the operating panel of the extruder. The guillotine shears are positioned on a movable base frame and accelerated up to web speed before the cutting process, thus preventing an accumulation of the film web in front of the shears. The cut sheets are forwarded to the stacking.
Longitudinal cuts can be integrated in esde Extrusion Lines for Flat Film and Sheets to cut the egde trim or for dividing up into individual webs.
The edge strips are guided by a traversing conveying system to the Edge-Trim Winders, whereby forming solid rolls. The wind-up shafts are electrically driven. The motor characteristics guarantee the adjustment of the rotational speed for increasing wound diameters. The winding up is without core, whereby the maximum outside diameter is 500 mm approximately and the winding width about 250 mm.
