OVALMATIC MODEL E8700 UNITYER
OVALMATIC MODEL E8700 UNITYER
The model E700 Unityer comprises a removable all-electric Tying Unit and a hydraulically operated stationary Compacting Station. All tying functions are AC gear motor driven using AC Vector Drive technology. The E9700 Tying Unit includes automatic waste wire coiling for disposal, a high capacity accumulator and automatic threading after a coil change. The Compacting Station provides side and top compacting functions powered by a small on-board HPU.
Features and Benefits
ALL ELECTRIC WIRE TYINGReduces potential problems and the environmental concerns of hydraulics.
ROTATING DISC ACCUMULATORHigh speed, accurate management of wire- virtually eliminates knots and jams.
AUTOMATIC WIRE THREADINGSimply inserting wire into the outer guide starts and completes the feeding sequence.
AC VECTOR MOTOR
- Drives cams in twister head
- Low cycle time
LOW FRICTION TRACKThe proven low friction passive track design requires no lubricants
ON BOARD PLC
- Touch panel operator interface built in diagnostics
- Safe 24 Volt DC controls
EASY ACCESSDoors and panels allow easy accessibility for inspection and maintenance.
SEPARATING MACHINESTying machine is easily separated from Compacting Station for easy access and maintenance allowing standby machine to be used.
ROTATING DISC ACCUMULATOR
- Provides complete control of wire feed and tensioning and accumulated wire
- Reduces twists, buckles and jams
