Shaftless Presses Offer Flexibility and Control |
4.9.99
If individual press units are driven with separate electric motors, unique control
opportunities exists. Gone are the mechanical drive shaft and gears and the propagation of
errors and adjustments in a connected system. Each electric motor can be controlled by a
fiber optic link to a central controller. Each press unit can also be adjusted, plates
changed, blankets washed, etc. when shut down or controlled independently of its
companions.
Makeready wastes can be reduced by individually altering press units as required without
as much interaction with other press operations. Wasted web lengths can also be reduced as
individual adjustments are made, eliminating the need to run the web through the entire
press.
