ABSTRACT:
A sheet material roll control device that comprises a series of protrusions that periodically intersect with each other while the sheet material roll rotates. One set of protrusions are located on a base while another set of protrusions are located on a roll plate. The roll plate is designed to fit on the end of a spindle that sits inside the roll core. In addition, attached to the roll plate and surrounding the spindle is an insert that rests flush inside the roll core. This insert fills the gap between the roll core and the outer shell of the spindle. With this insert, when the roll rotates, the spindle rotates with the roll, causing the roll plate to turn and periodically intersect protrusions located on the base, causing the rolling rate of the roll to slow down.
