Marzoli’s CM7 LP comber.

Combing machines reduce short fibers, neps and increase sliver evenness. However, building a solid and reliable comber is a very hard task: the intermittent movement of the nipper and of the detaching rollers, the perfect synchronization between all the drives and the always-higher requests on productivity make it the most-mechanically-solicited machine of the spinning mill.

Marzoli’s CM7 LP comber represents state-of-the-art combing technology. It guarantees top performances on cotton of any length, with a perfect selection of fibers in relation to the staple diagram and a substantial reduction of neps in the sliver. The machine, thanks to the variable speed of the circular comb and the revised kinematics of the nipper, can reach up to 600 nips per minute, with production levels up to 85 Kg/h.

According to Marzoli, a leading Italian supplier of textile machinery and components for short-staple fiber processing, the outstanding quality performances are ensured by several technical solutions: the jaws designed for perfect nipping throughout the entire width of the batt, the standing pendulum movement of the nipper to maintain minimum and constant distance between the jaws and the circular comb throughout the combing cycle, top-quality circular combs with 4 or 5 sectors with progressive point density, self-cleaning top combs, drafting system, followed by calender, located right on top of the coiler to avoid false drafts.

Besides, the automatic lap piecing technology installed on the CM7 LP allows to change the empty tubes with full laps and restart the machine automatically in less than 2 and a half minutes. This system not only increases efficiency but also has a positive influence on quality as it always entails the perfect overlay of the batts during lap change.
