Hydraulic reels HN with a supporting drum, type POPE, are intended for paper web reeling. The  paper web is reeled up at constant speed on a roll – the reel spool. The reel spool revolutions depend on down pressure induced by the carrying cylinder which is driven by a geared electric motor.

Design

The supporting drum can be made of cast iron or completely welded of structural carbon or stainless steel. Between stands there is a doctor with electromechanical oscillation installed for surface cleaning. On the PM control side, there is a fixed or free rope pulley according to the paper threading system into the reel. The supporting drum is equipped with an internal cooling system used for the paper web cooling coming from the PM drying part.

Tilting arms are operated hydraulically and they are mechanically coupled to keep their mutual positions and providing a uniform run. The loading levers are designed in the same way which as an addition can regulate the reel spool loading on the supporting drum for each lever separately. In the end position, the reel spool is stopped by hydraulic dampers and braked by hydraulically controlled brakes. A great emphasis is put on work safety during the reel operation. The reel is designed so that an access to dangerous spots and to squeezing points (between the reel spool and supporting drum) is prevented. Control of all reel functions can be done through the control board either in manual or fully automatic modes.
