    • A cushioning conversion machine (20) including a conversion assembly (30) which converts a continuous sheet of multi-ply stock material (22) into a three dimensional cushioning product (32) and a stock supply assembly (550) which supplies the multi-ply stock material (22) to the conversion assembly (30). The conversion assembly (30) includes a forming assembly (52) which inwardly turns lateral portions of the stock material (22) as the stock material (22) travels therethrough in a downstream direction. The stock supply assembly (550) includes a separating device (574) and/or constant-entry device (580) designed to minimize tearing due to excessive tension in the lateral regions of the stock material (22). Additionally or alternatively, the forming assembly (52) includes a shaping member (590) having protrusions in its turning perimeter and/or holding surface to modify the shape of the cushioning product. Another embodiment of stock supply assembly (350) includes a stock-dispensing device (370) which dispenses the multi-ply stock material (22) from a continuous sheet thereof and a transversely extending member which is positioned to engage at least one of the plies of the dispensed multi-ply stock material (22). The transversely extending member has end portions which are inwardly tapered relative to the central portions of the member and towards the adjacent ends of the member. The inwardly tapered lateral end portions being positioned to engage the ends of the lateral portions of the at least one ply of the stock material (22).

    • A cushioning conversion machine and method for converting sheet stock material into a cushioning dunnage product and wherein the tension in the stock material is controlled to avoid problems associated with improper tension. A conversion assembly draws the stock material from a stock supply and converts the stock material into a strip of cushioning, and a controller controls the operation of the conversion assembly. The conversion assembly is powered by a motor and the controller controls the operation of the motor in response to a sensed parameter related to the tension in the paper. In another embodiment, a torque control is interposed between the feed motor and feed components that engage the stock material.

    • A dunnage conversion machine (10) has an output chute (60) with a guard (70) that inhibits access to internal areas of the machine (10) through the output chute (60). Upstream of the output chute (60) the conversion machine (10) has a conversion assembly (16) that converts a stock material (14) into a strip of dunnage (20) as the stock material passes therethrough in a downstream direction. The output chute (60), through which the strip of dunnage (20) is discharged downstream of the conversion assembly (16), includes the pivotably-mounted guard (70) extending into the chute (60). The guard (70) has at its free end (72) both a forward glide surface (74) operative to glide along an outer surface of the strip of dunnage (20) as the strip moves in the downstream direction and a rearward glide surface (76) operative to glide along an outer surface of the strip of dunnage (20) as the strip moves in an upstream direction opposite the downstream direction.
