Abstract
A device for rotating a web material roll supported on a reel shaft having a pair of ends. The rotating device includes a female drive member coupled to one end of the reel shaft and defining an opening having a non-circular perimeter, such as a square opening. Also included is a male drive device having a rotatably powered drive shaft having an end that is congruent to the non-circular perimeter of the opening in the female drive member. The non-circular perimeter allows the reel shaft, and web material roll, to be positively rotated during unwinding. A telescoping assembly of the male drive device is capable of extending the drive shaft into the opening so as to allow co-rotation of the shaft and female member. An optional roll supporting cart may be employed to rotatably support the web material roll when aligning the male and female drive members.
