Sheet stock material configuration and apparatus, systems and methods for feeding sheet stock material to a dunnage system

A system, comprising:

• an expander configured for use with a dunnage machine, the expander including:
• a rear edge;
• a leading edge opposite to the rear edge, the leading edge spaced apart from the rear edge in a first direction;
• a first saddle portion;
• a second saddle portion spaced apart from the first saddle portion in a second direction directed from the first saddle portion to the second saddle portion, the second direction transverse to the first direction;
• a surface extending from the first saddle portion to the second saddle portion in the second direction;
• and
• a separator rod extending from the surface, the separator rod extending away from the rear edge towards the leading edge in the first direction.

A system, comprising:

• an expander configured for use with a dunnage machine, the expander including:
• a leading edge and a rear edge opposite to the leading edge, a taper extending from the leading edge to the rear edge;
• a first saddle portion;
• a second saddle portion spaced apart from the first saddle portion;
• a middle portion extending from the first saddle portion to the second saddle portion, the middle portion coupling the first saddle portion to the second saddle portion;
• and
• a separator rod between the first saddle portion and the second saddle portion, the separator rod extends outward from the middle portion, and the separator rod extends away from the rear edge towards the leading edge.
