Double unwinding station with automatic reel change
Up to 33% gain in production capacity
Two pneumatically acting clamping sleeves are used to hold one production and one spare part. A roller end or even material tear leads to the immediate lowering of all transport-determining drives. Subsequently, the roll end of the production roll is glued to the beginning of the spare roll. The adhesive site is followed until the arrival in the encasement zone. The production speed is then raised again to the last value driven. In order to keep the material tensile force constant regardless of the diameter, the roller diameters are continuously measured without contact and the required braking force is adjusted automatically. The scope of delivery includes two set-up aids, which make it much easier to replace and position coating casings during production.
