A device for manufacturing gas filled cushions from preconfigured film material. The device comprises a housing, a film roll holder for supporting a roll of preconfigured film material in a rotatable manner, a gas supply unit, a sealing unit, and conveying means for conducting the film material away from the roll and for conducting said film material along the gas supply unit and the sealing unit in a conducting direction. The device is mountable to a stillage in multiple positions.

A stock supply assembly for a dunnage conversion machine includes a stock material support having a support structure, such as a shelf for a stack of fan-folded sheet stock material. The shelf is movable between a relatively lower loading position and a relatively higher operating position vertically displaced relative to the loading position. In the process, the support structure maintains a consistent orientation as the support structure moves between the loading position and the operating position.

A cutting mechanism is provided for a dunnage conversion machine 10 that selectively cuts dunnage sheet stock drawable through the cutting mechanism. The cutting mechanism includes a frame and a pair of opposed cutting blades through which the sheet stock is drawable. The cutting blades include a driven blade and a biased blade, each supported relative to the frame for movement into and out of contact with one another. The driven blade is movable towards the biased blade to cut the sheet stock. The biased blade is biased against movement away from the driven blade to allow for self-adjustability to counter wear of one or both of the opposed blades. Contact of the opposed blades with one another causes the biased blade to be deflected away from the driven blade.

A machine for providing cushioning products of varying lengths from a supply of a web material having sequential transverse rows of inflated protrusions. A pair of opposing feed members form a feed nip for moving the web along a path of travel. At least one sensor detects location information for the sequential rows of inflated protrusions as the web travels along the path of travel. A severing device is moveable between (i) an engaged position to separate the web transversely or perforate the web transversely and (ii) a disengaged position. A controller is programmed (i) to receive the location information and (ii) to operatively control the severing device to move it to the engaged position when a selected row is in a determined position relative the severing device.

A Coiling device for spirally rolling-up a three-dimensional cushioning material made by a cushion forming device from a web-type source material (e.g. a roll or a Leporello-stack) of paper, can include a reel having at least two deflectors, and having a rotational axis extending in vertical direction. The deflectors can be a mandrel, hook, deflector edge, or the like.

A machine for producing cushioning material comprises: a frame; at least a first supply assembly preferably mounted on said frame, the first supply assembly supplying a first web-type feed material; and at least a first transformation assembly mounted on said frame which transforms the first web-type feed material into a first cushioning material. It is suggested that it further comprises: at least a second supply assembly preferably mounted on said frame, the second supply assembly supplying a second web-type feed material; and at least a second transformation assembly mounted on said frame which transforms the second web-type feed material into a second cushioning material.

Disclosed herein are protective packaging stock material units that are used in a dunnage system. A dunnage system includes a dunnage conversion machine and a supply station. The supply station is a cart that includes a biased support that is connected to a vertical side support. The biased support is movable from an open position to a closed position with respect to opposing vertical side supports. In the closed position, the biased support is configured to at least partially block the opening between the opposing vertical side supports. In the open position, the biased support leaves the opening between the opposing vertical side supports sufficiently open to load fanfold stock material therein. The biased support is biased towards the closed position and the open position. The supply station also includes an alignment device forming a funnel positioned under its base. The alignment device receives a dunnage machine stand base causing the supply cart to consistently align with the stand base in response to the stand base being slid into engagement with the alignment device.

A dunnage conversion machine includes a drive mechanism configured to deform a stock material into dunnage. The drive mechanism may include a roller with an outer surface having a first shape, and another roller having an outer surface with a second shape different than the first shape. The dunnage conversion machine also may include a cutting mechanism that includes an anvil having a curvilinear surface, and a cutting portion, with the anvil and the cutting portion being configured to cut the dunnage. The dunnage conversion machine also may include an inlet chute configured to feed the stock material to the dunnage conversion machine. The inlet chute may include a protrusion located within an interior channel of the inlet chute and configured to restrict larger objects, such as the fingers and hands of an operator, from moving down the interior channel.

A modular dunnage machine assembly consists essentially of discrete modules of grouped dunnage machine components, the dunnage assembly being usable for expanding, stitching and/or compressing and/or pulling, and cutting, sheet stock material into separate strips of dunnage or other cushioning product. The modules can be individually mounted to the assembly and stabilized thereon, before being securely connected to the assembly, for purposes of component part replacement or initially assembly. In some embodiments, the modules consist essentially of a gear and motor module, an expander module, a power supply module, an internal mounting frame module and a cutter module.

A dunnage conversion machine includes a drive mechanism configured to deform a stock material into a continuous length of dunnage. The machine also includes a cutting device configured to sever a piece of the dunnage from the continuous length of dunnage. The cutting device includes a grip configured to move to a closed position at which the grip exerts a force on the piece of dunnage to retain the piece on the machine until the piece is pulled away from the machine, at which point the grip moves to an open position and the machine advances the continuous length of dunnage to commence another cutting cycle.
