<p>The invention is an improved system for rewinding fabric, particularly such fabrics which are more or less impervious and tend to entrap air between successive layers of the fabric being wrapped upon a core means as the rewinding proceeds. The system may be operated in a horizontal rolling mode or in a vertical rolling mode. When operating in the horizontal mode the system utilizes the weight of the supply roll (52) to directly maintain more or less air-free layers, alternatively a minimum mechanical pressure is maintained at the supply roll in the horizontal mode as the weight of the supply roll diminishes near the end of the supply. When operating in the vertical mode, the pressure means is reversed, utilizing a constant mechanical pressure of the roll, or rolls, being wrapped against the supply roll (72) as the rewinding proceeds. This direct pressure system to maintain more or less air-free layers eliminates the tedious and time-consuming threading of the fabric over and under a complicated system of a plurality of idler rolls, drive roll, rider roll, and a core.</p> |
