Abstract
Paper industry deals with procedures for conceptual and final design of a machine intended for unwinding paper that remains on reels during a certain phase of paper producing. Design procedure of the machine is a subject of this paper. The machine was designed as a mechatronic unit consisting of a mechanical part, an electric part and a pneumatic part. 3D CAD/CAM system Pro/ENGINEER was used for the design of the mechanical part. For the automation processes the PLC unit connected with the frequency changing unit and asynchronous drive were used as a central drive for the unwinding machine.
Highlights
In order to make production of paper faster, more effective and environmental friendlier, the paperwork in Ružomberok defined a task, the solution of which would approximate its production technology chain toward aforementioned goals

Summary
In order to make production of paper faster, more effective and environmental friendlier, the paperwork in Ružomberok defined a task, the solution of which would approximate its production technology chain toward aforementioned goals. Manually performed removal of wound-up rest of web paper that remains on a reel spool after a web unwinding – during a paper production would be automated. The paper remains wound-up on a reel spool due to a used technology of production and due to production process tolerances. With the use of knife, an operator had to cut the remaining paper off a reel and store the removed paper in a container from where it went for further processing. The objective of the defined task was to minimise the manual operation of the removal of the rest of paper from a reel and speed up the process. The overall objective of the task was to design and to manufacture a fully automatic machine that would be able to unwind remained paper from a reel and would direct it for a recycling process. The device can be divided into three basic parts: – a mechanical part consisting of a machine frame, movable mechanisms, a machine covering, – an electric part consisting of electric drive and power supply as a power part and a control part with PLC computer and sensors, – a pneumatic part with pneumatic cylinders, valves and devices for compressed air parameters control
