Abstract
A cushioning conversion machine for converting a sheet-like stock material into a cushioning product. The machine includes a forming assembly which forms the sheet-like stock material into a three-dimensional strip of dunnage; a stock supply assembly which supplies the stock material to the forming assembly; a feed assembly which feeds the stock material through the forming assembly; and a cutting assembly which cuts the strip of dunnage into sections of a desired length. The forming assembly includes a chute having an inlet end which is outwardly flared in a trumpet-like fashion to facilitate passage of the sheet-like stock material into the chute.
