Abstract
A cushioning conversion machine (20) including conversion assemblies (24) which convert a sheet stock material into a relatively low density cushioning product. The conversion assemblies (24) include a feed/cut assembly (26) having a feed device (100), a cut device (200), and a drive device (300). The drive device (300) is operable in two opposite directions and alternately drives the feed device (100) and the cut device (200). Clutch (134) and/or clutch (234) are provided which allow reverse operation of the feed device (100) and/or the cut device (200). A brake (238) prevents inadvertent movement of the moving components (220, 222) of the cut device (200). The power transmission from the drive device (300) to the feed device (100) and the cut device (200) includes a gear train (136, 236, 306) . These and other features of the feed/cut assembly (26) improve operating efficiency and/or simplify assembly procedures.

6632165 - Paper conversion dispenser machine

A paper conversion dispenser machine for converting sheet-like material into a relatively low density cushioning dunnage product. The machine has a stock supplying assembly that supplies at least one stock paper roll, a shaping member for crumpling and converting sheet-like material of the roll(s) into a three-dimensional shape that consists of a pre-entry section with two side entry guiding rollers for guiding and reducing the sheet-like material of a supplied width to a narrower width non linear crumpled stream of paper, and an entry section with two side entry rollers to guide and reduce the crumpled down stream of paper to an even narrower width relatively low density cushioning dunnage product. The machine also has a guiding tunnel of a substantially uniform cross section, a feed mechanism with driving rollers for driving the stock material through the shaping member, and an automatic cutting set for cutting the dunnage product.

7186208 - Cutterless dunnage converter and method - Owned by Ranpak Corp. (Concord Township, OH)

A tabletop converter has a conversion assembly that inwardly gathers and crumples a stock material to form a strip of dunnage. The conversion assembly includes a feeding assembly that moves the stock material and a controller that controls the feeding assembly to operate in both a forward direction and a reverse direction. To automatically separate a discrete dunnage product from the strip, a holder grabs and holds the strip of dunnage at a holding location downstream of the feeding assembly. The feeding assembly then operates in a reverse direction and urges the strip away from the holding location. This causes the strip to separate at or between the holding location and the feeding assembly, leaving a discrete dunnage product ready for use. The converter is mounted to a stand that allows the converter to rotate relative to part of the stand about both a horizontal axis and a vertical axis.

7125375 - Dunnage conversion machine with translating grippers, and method and product - Owned by Ranpak Corp. (Concord Township, OH)

A dunnage conversion machine for converting stock material into a dunnage product includes a forming assembly and a pulling assembly. The pulling assembly includes at least two grippers movable together through a transfer region in opposition to one another and cooperative to grip therebetween the dunnage strip for advancing the dunnage strip through the transfer region, and at least one of the grippers including an aperture operative to gather and laterally capture therein the dunnage strip as the grippers move through the transfer region. Also disclosed is a severing assembly including a movable blade and a reciprocating actuator connected to the blade by a motion transmitting assembly that moves the blade through a full severing cycle upon a stroke of the actuator in either direction. Also disclosed is a void fill dunnage product including a three dimensional crumpled strip of dunnage round in cross-section and including at least one ply of sheet material having, in cross-section, a crumpled multi-lobed undulating body, with the lobes thereof extending longitudinally and being dispersed in an irregular pattern.
