Abstract
An unwind spool assembly for dispensing material wound into a roll includes a rotatable shaft and a mounting block rotatably mounted on the shaft for rotation about the shaft in a wind direction and an unwind direction, wherein in the unwind direction the material unwinds from the roll, and in the wind direction the material winds onto the roll. A biasing member interposed between the shaft and the mounting block rotatably biases the mounting block toward the wind direction. In another embodiment, a slip clutch is fixed to the shaft for maintaining a drag on the shaft as the shaft rotates in the unwind direction to maintain tension in the material unwinding from the roll. In yet another embodiment, the unwind spool assembly includes a spool core for holding the roll of material. The spool core is rotatable about an axis, and at least one flange extending radially from the core is rotatable about the axis independently of the core.
