摘要： A method and apparatus for the production of thermoplastic film air cell cushioning product. The method and apparatus utilize as stock material flexible thermoplastic film formed of a composite of a stratum of relatively high density, high melting point thermoplastic and another stratum of relatively low density, low melting point thermoplastic bonded to the first mentioned stratum. A sheet of the composite thermoplastic film material is heated well above the melting point of the low melting point stratum but below the melting point of the high density stratum and is applied to a rotating forming drum and vacuum formed, to produce the air cells in the product, and then a sheet of the film material which has been heated, is generally immediately laminated to the heated sheet on the drum, with the temperature of the second mentioned sheet being at its application to the embossed sheet, below the melting point temperature of the low density stratum and at a maximum temperature approximating the mean temperature between the heat softening point and the Vicat softening point of the low density stratum, with the second mentioned sheet being applied with associated pressure to the heated embossed first sheet on the rotating forming drum. The apparatus is relatively compact and the method and apparatus are energy efficient.

摘要： A dunnage conversion apparatus for dispensing a cushioning wrap material from a roll of expandable slit sheet material is described. The roll of expandable slit sheet material includes an expandable slit sheet material in an unexpanded state. The expandable slit sheet material is pulled from the roll of expandable slit sheet material and expanded to a pre-expanded state and an expanded state. To expand the expandable slit sheet material and form the cushioning wrap material, a stretching force is applied to the expandable slit sheet material in a stretching direction as it is pulled from the roll of expandable slit sheet material. Accordingly, the dunnage conversion apparatus includes a tensioning device for assisting in the application of such stretching force.

摘要： A machine for converting a sheet material into a relatively less dense dunnage product includes a forming assembly and a feeding assembly downstream of the forming assembly. The forming assembly is configured to form the sheet material into a tubular shape with lateral edges of the sheet material adjacent one another. A deflector at a downstream end of the forming assembly is configured to engage the lateral edges of the sheet material and to urge the lateral edges into an interior of the tubular shape. This juxtaposes lateral edge portions of the sheet material adjacent the respective lateral edges. A forming channel at a downstream end of the forming assembly faces the deflector to receive the lateral edge portions and shape them into a tab. Finally, the feeding assembly includes rotating connecting members that engage and connect the overlapping lateral edge portions of the sheet material forming the tab.

摘要： A packaging system for transferring a dunnage product to a packaging container includes a dunnage sensor configured to detect the dunnage product registered at an alignment reference plane in a staging location. The packaging system also includes a package sensor configured to detect the packaging container registered at the alignment reference plane in a loading location. A dunnage placement apparatus is configured to transfer the dunnage product from the staging location to the packaging container in the loading location after both the dunnage sensor detects the dunnage product registered at the alignment reference plane in the staging location and the package sensor detects the packaging container registered at the alignment reference plane in the loading location.

摘要： A conversion assembly for a dunnage conversion machine includes both a downstream pair of rotatable members and an upstream pair of rotatable members upstream of the downstream rotatable members. The downstream rotatable members include a pair of gears, and each gear has a plurality of teeth and is rotatable about a respective axis. The gears are positioned so that the teeth of one gear are sequentially interlaced with the teeth of the other gear as the gears rotate. The upstream rotatable members include a pair of feed wheels, and the gears and the feed wheels define a path for a sheet stock material from between the upstream pair of feed wheels to between the downstream pair of gears. The rate at which the sheet stock material is advanced by the feed wheels is the same as the rate at which the sheet stock material is advanced by the gears.

摘要： An apparatus for conforming a dunnage element about contents in a container includes an array of pushers having biased end portions that are movable relative to one another and having end faces for engaging the dunnage element. The end faces of the pushers are biased to an extended state and are movable against the bias in response to engagement of the end faces with the contents and with the dunnage element between the end faces and the contents. At least one of the pushers is movable against the bias separately from a remainder of the pushers to enable conformance of the array to the shape of the contents. The pushers are mounted to a carrier at respective mounts. A motive device is coupled to the carrier and is configured to collectively move the mounts vertically.

摘要： A supply of single-ply, fan-folded sheet stock material includes a holder that facilitates simultaneously loading multiple plies of sheet stock material into a dunnage conversion machine for conversion into a dunnage product. The holder has inclined support surfaces and intersecting support walls that support the support surfaces in their inclined orientations. The holder has a W-shape cross-section, with inclined outer support surfaces and inclined inner support surfaces that may meet in the middle. The inner support surfaces generally are perpendicular to adjacent outer support surfaces to support a generally rectangular stack and sub-stacks of single-ply, fan-folded sheet stock material. The inclined support surfaces of the holder facilitate splitting the stack in half and supporting the two sub-stacks so that pages on top of the two stacks, connected by a center fold line, can be drawn into the conversion machine simultaneously.

摘要： A dunnage conversion machine converts a sheet stock material into a dunnage product that is relatively thicker and less dense than the stock material. The conversion machine includes a conversion assembly that draws the sheet stock material therethrough and randomly crumples at least a portion of the sheet stock material. Before severing a discrete dunnage product of a desired length from the substantially continuous length of sheet stock material, the conversion assembly temporarily advances the sheet stock material therethrough while minimizing or eliminating the random crumpling of the sheet stock material in a reduced-crumpling zone, and then cuts the sheet stock material in the reduced-cutting zone to reduce or eliminate the production of scrap shards of sheet stock material.
