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.

[ What is claimed is:] [1.] A device for controlling the rolling of a material roll comprising:a) a stationary base having an inside face with a recessed region;b) a first plurality of protrusions positioned on said inside face of said stationary base;c) a spindle for frictionally engaging said mate

[ What is claimed is:] [1.] A device for controlling the rolling of a material roll comprising:a) a stationary base having an inside face with a recessed region;b) a first plurality of protrusions positioned on said inside face of said stationary base;c) a spindle for frictionally engaging said material roll and rotating about an axis within said recessed region on said stationary base;d) at least one roll plate attached to said spindle for rotation therewith, said roll plate having a first surface attached to said spindle and a second surface facing said inside face of said stationary base; ande) a second plurality of protrusions arranged on said second face of said roll plate, wherein rotating said material roll causes said second plurality of protrusions to frictionally engage said first plurality of protrusions and causes the material roll to slow its rotational speed.
