Abstract
An unwinding apparatus supports a reel (60) of web material (22) which is to be unwound and directed into a printing unit (14) having a front/operator side and a rear/gear side. The unwinding apparatus comprises a frame (16) including a rear side part (28) located at the rear side of the printing press (14), and front side parts (24, 26) located at the front side of the printing press (14). The front side parts (24, 26) define an opening in the frame (16). Guide and locating bars (38) on the frame (16) extend from the rear side part (28) to the front side parts (24, 16) of the frame (16). The apparatus further comprises a movable reel cartridge (18) having front and rear cartridge frame parts (64, 66) for supporting the reel (60) of web material (22). The reel cartridge (18) is movable through the opening in the frame (16) and onto the guide and locating bars (38) to locate the reel (60) in its operating position.
