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.
Claims17
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 generally downstream with respect to the path and having a convex shape across the path, such that the cutting edge engages and sequentially initiates cuts through the line of dunnage 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 apparatus comprising a cutting member having a cutting edge extending generally downstream with respect to the path and having a convex shape across the path, the cutting edge including teeth that are aligned along the cutting edge such that the tips of the teeth extend generally downstream and together form the convex shape, such that the cutting edge engages and sequentially initiates cuts through the line of material when the line of dunnage is pulled against the cutting member, thereby reducing cutting forces, the tear-assist apparatus configured to operably pull the line of dunnage upstream against the cutting members to initiate the cuts.
