Abstract
A material dispenser having a dispensing member configured to dispense a line of the material along a path in a downstream direction, and a cutting member having a cutting edge extending generally downstream with respect to the path. The cutting member having a convex shape across the path, such that the cutting edge engages and sequentially initiates cuts through the line of material when the line of material is pulled against the cutting member, thereby minimize cutting forces.
Claims31
A dunnage apparatus, comprising:
- a converting station that converts a line of high-density material into low-density dunnage and dispenses the dunnage along a path in a downstream direction;
- and
- a cutting member having a cutting edge extending across the path downstream of the converting station along a curved shape that extends across at least the majority of the path, such that the cutting edge engages and sequentially severs the line of dunnage across the path when the line of dunnage is pulled against the cutting member, thereby reducing cutting forces.
A dunnage apparatus, comprising:
- a converting station that converts a line of high-density material into low-density dunnage and dispenses the dunnage along a path in a downstream direction;
- and
- a tear-assist unit comprising a cutting member having a cutting edge extending generally downstream with respect to the path and having a curved shape across the path, the cutting edge including a plurality of teeth that are aligned along the cutting edge such that the plurality of teeth extend from the cutting edge generally downstream with respect to the path and together form the curved shape, such that the cutting edge engages and sequentially initiates cuts through the line of high-density material when the line of dunnage is pulled thereagainst, the tear-assist unit being configured to operably pull the line of dunnage upstream against the cutting edge to at least partially sever the line of dunnage.
