Two differential friction shafts on rewinders, OD 60mm, dynamicaly balanced, hardened flange Appropriate for friction rings of different sleeve diameters.
Roll diameter up to 620mm / 850mm
Digital tension control via I/P proportional pressure valve
Max. tension for both shafts in total: 400N (at min. diameter), 250N (at max. diameter)
Taper curve adjustable in 16 points (graphical representation on HMI)
Memory for 3 different “taper” characteristics
Lay-on rollers (EPDM rubber) for both shafts (automatically seaprately digitaly adjustable pressures)
Additional aluminum rollers (alternative to rubber-coated rollers)
Pneumatic clamping of slitted strips (while changing cores)
Automatic stop at set-length or set-diameter
Lasers for core positioning system on both shafts
