μ,
Aluminium laminating composites 40 – 150g/m2
Embossed aluminium 105 – 160μ
Rewinder: Pneumatic expansion shafts for 76mm and 150/152mm sleeves
Friction shafts for 76 mm and 150 mm sleeves
The finished rolls are wound on pneumatic expansion shafts or friction
shafts.
The roll is removed by pushing it onto an unloading rack.
The machine is powered by DS motors.
The two DS motors of the winding system are electronically controlled,
which automatically reduce the speed of the winding shafts as the
winding diameter increases.
The input option and preselection of the winding pattern is
available.
The rubberized contact rollers are each mounted in two movable support
arms.
The support arms are operated by pneumatic cylinders, which generates
a uniform pressure G5752434 force.
Unwinder: Shaftless pick-up of the mother roll with pick-up heads for
76 mm and 150/152 mm cardboard or steel tubes.
Roll weights up to 1500 kg
Narrowest roll width 300 mm
The machine is built as a compact version, in which the shaftless
unwinder
integrated into the machine frame.
The nut roller is picked up shaftlessly, via pneumatically clampable
and replaceable heads with a diameter of 76 mm and adapter clamping
heads with a diameter of 150/152 mm. These can be used to pick up
cardboard tubes.
The two roller carrier arms are individually adjustable axially. This
makes it possible to accommodate mother rolls in different widths.
