E9700

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 TYING
Reduces potential problems and the environmental concerns of hydraulics.


ROTATING DISC ACCUMULATOR
High speed, accurate management of wire- virtually eliminates knots and jams.


AUTOMATIC WIRE THREADING
Simply 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 TRACK
The 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 ACCESS
Doors and panels allow easy accessibility for inspection and maintenance.


SEPARATING MACHINES
Tying 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
