10 and 20mm widths are regularly being converted across the Bimec range
at maximum speeds up to 700m/min.
These results can be credited to Bimec's advanced engineering and
software design and the versatility of IES differential rewind shafts.
Bimec continue to be the converter's choice with 6-machines installed
locally in the past 12-months for flexible packaging and general
...made possible with IES differential shafts
Web Dynamics offer IES differential rewind shafts for new installations
or to retrofit to existing equipment.
This style of differential shaft has become the industry standard, fast
replacing traditional spacer/core type shafts. Cores can be placed at any
point and are immediately locked when the core is rotated. This
dramatically reduces machine down-time and make-ready.
In the past 5 years all Bimec slitter installations in Australia/New
Zealand have incorporated IES differential rewind shafts.
IES differential shafts can often be retrofitted to existing machines
with minimal modification.
Differential shafts offer unprecedented control of tension without
problems associated with dust or core consistency and also allow for rolls
of different widths to be wound on the same spindle.
IES differential shafts are available for core IDs of 45mm to 152.4mm
and can be fitted with custom made steel journals to suit any machinery.
