Abstract
A creel, such as may be used to supply fiberglass roving to a production process, includes an enclosure and a number of rotatable axles held within the enclosure. Each of the axles is of a shape and size to be inserted into a bobbin of roving. The creel also includes a drive mechanism coupled to each of the plurality of rotatable axles, the drive mechanism synchronizing the rotation of the axles. Bobbins of roving may be stacked on the axles and connected to provide continuous roving. As roving is drawn from the creel, the rate of rotation of the axles may be selected to counteract twisting of the roving that would otherwise result.
