drupa 04 Report Binding & Finishing — Building Better Binderi

For example, if the repeat is 18˝ rather than the 24˝ cylinder, the 6˝ difference is compensated for by quickly advancing the die cylinders with the servomotor, resetting them to produce an 18˝ repeat. This is just one example of the use of servo-motors and stepper motors in postpress equipment. As in the pressroom, bindery equipment is quickly becoming gearless, shaftless and digitally controlled. This permits greater positioning control, and eliminates gear backlash and drive train wear.
