Downsized cushioning dunnage conversion machine and cutting assemblies for use on such a machine

A cutting assembly for a cushioning dunnage conversion machine for converting sheet-like stock material, such as paper in multi-ply form, into cut sections of relatively low density pad-like cushioning dunnage product, said machine comprising a frame including a frame base plate having an upstream end and a downstream end, a first upstream frame end plate extending generally perpendicularly from said upstream end of said frame base plate and a second downstream frame end plate extending in substantially the same direction as said first frame end plate from said downstream end of said frame base plate;

• a forming assembly, mounted on said base frame plate intermediate said upstream end and said downstream end, which causes inward rolling of the lateral edges of such sheet-like material into a generally spiral-like form whereby a continuous unconnected strip having two lateral pillow-like portions separated by a thin central band is formed;
• a stock supply assembly, located upstream of said forming assembly and mounted on said first frame end plate, which supplies such stock material to said forming assembly;
• a pulling/connecting assembly, located downstream of said forming assembly and mounted on an upstream side of said second frame end plate, which pulls such stock material from said stock supply assembly and through said forming assembly to form such continuous unconnected strip and which connects such continuous unconnected strip along such central band whereby a coined strip of pad-like cushioning dunnage product is formed;
• said cutting assembly being mounted on an opposite downstream side of said second frame end plate and thereby being located downstream of said pulling/connecting assembly, for cutting such coined strip into cut sections of a desired length, said cutting assembly comprising:
• a first blade mounted on said second frame end plate;
• a second blade also mounted on said second frame end plate and positioned to coact with said first blade to cut such coined strip into cut sections;
• a motor for powering said cutting assembly;
• a cutter linkage connected to at least one of said blades;
• a drive linkage pivotally connected to said cutter linkage;
• a motion disk connected to said drive linkage;
• and
• a shaft connecting said motion disk to said motor.
