摘要： A bound pad presents a compact and convenient form of providing a two-ply construction that includes a slit-sheet stock material that may be positioned on or hung from a flat surface at the end-user's site. The bound pad includes sheets of slit-sheet stock material that are interleafed with non-die cut separator sheets. The sheets are bound together adjacent one edge, and may be weakened adjacent the bound edge to facilitate their removal from the bound pad during use. A user creates tension by pulling a free edge of the sheet of slit sheet material away from the bound edge, thereby expanding the slit material sheet to form an expanded packaging material. The user places an article on the bound pad, wraps the article in the sheets, and tears the sheets to remove the wrapped article from the bound pad.

摘要： A dunnage conversion system for expanding an unexpanded slit sheet stock material to form an expanded dunnage product. The dunnage conversion system includes a converging chute to inwardly gather laterally-extending edges of sheet stock material towards one another, causing random crumpling of the sheet stock material to form a modified ply. The conversion system also includes feed wheels that advance the modified ply through the converging chute and pinch rollers that cooperate with the feed wheels to expand the modified ply traveling between the feed wheels and the pinch rollers to form a dunnage product. The expanded dunnage product is expanded both in a longitudinal feed direction and in thickness as compared to the unexpanded slit sheet stock material, and thus is a three-dimensional product having increased volume and lower density per unit of length as compared to the unexpanded slit sheet stock material.

摘要： A dunnage conversion system (20) for expanding an unexpanded slit sheet stock material (23) to form an expanded dunnage product (26). The dunnage conversion system includes a converging chute (28) to inwardly gather laterally-extending edges of sheet stock material towards one another, causing random crumpling of the sheet stock material to form a modified ply. The conversion system also includes feed wheels (120) that advance the modified ply through the converging chute and pinch rollers (122) that cooperate with the feed wheels to expand the modified ply traveling between the feed wheels and the pinch rollers to form a dunnage product. The expanded dunnage product is expanded both in a longitudinal feed direction and in thickness as compared to the unexpanded slit sheet stock material, and thus is a three-dimensional product having increased volume and lower density per unit of length as compared to the unexpanded slit sheet stock material.

摘要： In some illustrative embodiments of the present invention, a novel expandable slit paper expansion device design is provided that, among other things, avoid complications of prior systems and eliminates the crushing effect of the rollers. Among other things, the preferred embodiments provide a unique structure that provides a novel “S” shape path of the expandable slit sheet paper, such that the expandable slit sheet paper is tortuously weaved between at least two expansion rollers without being compressed there-between, in a manner that the expandable slit sheet paper follows along surfaces of the expansion rollers without pinching or compression that occurs in the background art.

摘要： 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.

摘要： A supply of inflatable pouches includes an inflatable web defining a series of inflatable chambers, a longitudinal fold in the web such that the web is configured in the form of two juxtaposed inflatable panels joined together at the longitudinal fold, and a series of transverse seals that bond the panels together to form a series of inflatable pouches between pairs of the transverse seals.

摘要： The invention relates to a paper processing product and, in particular, to a shredder that crinkles paper stripes. The shredder has a shaft set driven by a motor. The shaft set includes at least two shafts rotating in opposite directions. Cutting blade sets are mounted on the shafts. Paper enters the entry of a paper passage formed by the shafts, and gets shredded into chips by the cutting blades. Since the exit of the paper passage is provided with a movable stopper, paper stripes are pushed by the rotating cutting blades to pass the stopper and become crinkled. The stopper is triggered to open by a certain force, letting the paper stripes fall. In addition to the functions of a usual shredder, the paper stripes thus made can be recycled.

摘要： A dunnage-producing system includes a dunnage conversion machine for converting a stock material into a relatively less dense dunnage product, a supply of stock material, and a guide element. The conversion machine is rotatable about a substantially vertical axis. The supply of stock material includes a support for the stock material that is movable relative to the conversion machine, such as for replenishing the stock material. The guide element is rotatable with the conversion machine to maintain a consistent position relative to the conversion machine, thereby consistently positioning the support relative to the conversion machine to avoid tearing or jamming problems associated with an improperly aligned supply of sheet stock material.

摘要： The mold structure includes an upper mold, a pressing mold and a bottom mold. The upper mold has downward pressers and knives. The knives are interlaced with the pressers. Each of the knives is higher than adjacent one of the pressers. The pressing mold is flexibly connected under the upper mold and has through holes for being passed through by the pressers and knives. The bottom mold is arranged under the pressing mold and the upper mold for supporting a sheet of paperboard to be pressed and cut.
