Abstract
A resistance mechanism for a sheet product dispenser for dispensing a length of sheet product from a roll of sheet product rotatably supported by the sheet product dispenser is provided. The resistance mechanism includes an arm configured to frictionally engage a surface of the roll of sheet product, and a spring attached to the arm and configured to bias the arm into engagement with the surface of the roll of sheet product, such that the resistance mechanism provides a pull force resistance opposing a pull force applied to a tail portion of the roll of sheet product.
