'''Crucial property''' of the machine is the speed it can be operated. Usually the input rollstock is much heavier and longer than the output rollstock. Never-the-less, the longer the output rollstock, the less the machine needs to be stopped for offloading the output rollstock.

Slitting machines are commonly '''classified by their rewinding design'''. In case of [[cantilever slitter rewinder]], the offloading of the rewinded rollstock is manual. Center surface technology uses powered shafts that makes it possible that the rewinding shafts can take much heavier load and longer length of film than the cantilever, making it possible that the machine is stopped less often for offloading.  Turret technology provides the highest level of automation for offloading between the three different technology.

Key element of the machine is the slitting knife. The two main type of the knife are the so called razor in the air and the circular blade. Earlier requires less set-up time, while the later has longer life cycle and it can usually handle thicker materials than the earlier one. Also, slitter machine with a circular blade can usually run faster without compromising film tension or ruining quality of the print on the film.
