Glossar: Suction head

MABEG ClassicFeed suction head

A suction head (also referred to as a sheet separator) is an assembly in the sheet feeder of a sheet processing machine (e.g. offset, gravure and screen printing machines, as well as varnishing, laminating, die cutting, foil stamping, folding and metal decorating machines).

A suction head in the classical sense (MABEG ClassicFeed) has an enclosed control system (controller drum) that controls all cycles – such as bottom blowing (carrier air), separation and transportation of the uppermost sheet – during each revolution. During sheet separation, the uppermost sheet is continuously stabilised and controlled by the relevant components (trigger foot, separator sucker and forwarder sucker). In order to reduce friction, compressed air is blown between the individual layers of the material stack at the side and rear. At the same time, the uppermost sheet in the stack being processed is lifted up via vacuum. The suction head is configured accordingly depending on the customer-specific requirements and particular field of application.

As an alternative to regular ClassicFeed suction head, MABEG NewTec suction heads are the result of consistent progress and cuttingedge automation technology. Based on the patented KAjector technology from company Kasprich, a suction head generation has been exclusively developed which boasts improved performance at reduced energy consumption.

The MABEG NewTec suction head family comes without the entire controller drum and air control. This makes most of the air hoses superfluous as well. Vacuum and compressed air is generated directly inside the suction head during each process step by means of specially designed and controlled KAjector nozzles. These ejector nozzles are controlled individually through an intelligent microcontroller, so that energy will only be consumed if vacuum and compressed air is actually needed. The integrated control software permits the switching cycles to be programmed almost without limitations. The timing can so be adapted freely to the process and actual machine speed. Highest running smoothness and perfect sheet arrival are thus achieved through the entire speed range. This does not only make the MABEG NewTec suction head family 50 % more energy-efficient and substantially reduces wear compared with the classic suction heads, but it also opens horizons for further performance improvements and even more precise sheet feeding.
