Dispenser for rolled sheet materials

Abstract

In one aspect, the present disclosure is directed to a sheet material dispenser that includes a feed roller that is rotatable to facilitate dispensing of the sheet material from a discharge in a housing of the dispenser. The dispenser can have a cutting assembly that includes a cutting blade and at least one movable support coupled to the cutting blade that is actuated with rotation of the feed roller to cause movement of the cutting blade to at least partially cut, score, or perforate the sheet material during dispensing thereof. The dispenser also can have a biasing assembly coupled to the feed roller body to assist rotation of the feed roller body and/or movement of the cutting blade. Other aspects also are described.

What is claimed is: 
     
         1 . A dispenser comprising:
 a feed roller configured to feed a sheet material from a supply of sheet material;   a cutting assembly comprising:
 a cutting blade at least partially disposed within the feed roller; and 
 at least one movable support coupled to the cutting blade and including a first portion positioned along an interior surface of the feed roller, and a second portion configured to move along a cam track positioned within the feed roller; and 
 at least one biasing member coupled to the feed roller body and configured to assist rotation of the feed roller and/or movement of the cutting blade at least partially through the feed roller to at least partially cut, score, or perforate the sheet material during dispensing of a selected portion thereof.
