摘要:
A material dispenser having a dispensing member configured to dispense a line of the material along a path in a downstream direction, and a cutting member having a cutting edge extending generally downstream with respect to the path. The cutting member having a convex shape across the path, such that the cutting edge engages and sequentially initiates cuts through the line of material when the line of material is pulled against the cutting member, thereby minimize cutting forces.

A supply structure (114) for a supply (16) of fan-folded sheet stock material (20), which is positionable relative to a cushion conversion machine to provide thereto the fan-folded sheet stock material for conversion thereof into packaging cushioning. The supply structure includes two or more supports (146), each of the supports including a base (148) and a riser (150) extending upwardly from the base. The base and the riser are structured and arranged to cooperatively accommodate a stack of the fan-folded sheet stock material.

A dunnage system may include a converting station including a converter configured for pulling in a stream of sheet material and converting the material into dunnage, and an inlet guide having an inlet surface that is coiled such that first and second ends of the inlet surface are discontinuous with each other to define a gap therebetween, the inlet surface configured to channel the sheet material into the converter. A cutter for a dunnage system may include a blade with first and second phases of serrations that are coextensive over at least a portion of the blade, the first phase providing cutting serrations for cutting the dunnage, and the second phase comprising ledges for focusing the cutting and preventing or reducing bunching of the dunnage towards a side of the blade. A method of converting dunnage may also be provided.

A dunnage conversion machine (10) and corresponding method for converting a supply of sheet stock material into a relatively less dense dunnage product includes a conversion assembly (20) that converts sheet stock material into a dunnage product, and a tension-adjusting assembly (26) having a sequence of transversely extending members (28) disposed upstream of the conversion assembly (20). The transversely extending members (28) engage the stock material and help to prevent or to minimize excessive edge tension and/or the tearing associated therewith, while maintaining sufficient tension for proper tracking, especially for the conversion of single ply, lesser quality and/or short fiber paper, and/or otherwise improves or enhances the conversion process. The transversely extending members (28) are generally aligned end-to-end, and define a path for the stock material from a supply thereof, via a stock supply assembly (15) to the conversion assembly (20).
摘要:
A dunnage production system for producing coiled strips of dunnage includes a supply of strip-like dunnage, a coiler adjacent the supply and rotatable about a coiling axis for coiling a strip of the strip-like dunnage into a coil having a coiled configuration, and a tube aligned with the coiling axis. The tube has an internal diameter sized to receive the coil from the coiler in a discharge direction parallel to the coiling axis. The tube is capable of holding at least one coil in its coiled configuration until it is removed from the tube.

Various embodiments of the present disclosure provide a reusable valve (10) in which a seal portion (124) is co-molded with and overmolded to the valve stem (30) to provide a secure mechanical bond therebetween. In one embodiment, the valve includes a snap fit between the valve stem (30) and a retaining cap (50) to provide easy assembly of the valve as well as an efficient and compact retention mechanism for a biasing spring (40) and the valve stem (30) in relation to the valve housing (20). In one embodiment, the valve includes an easy-to-use opening and closing mechanism that provides tactile feedback to the user when moving the valve stem to an open position and to a closed position to inflate, deflate, or maintain air or gas pressure in the inflatable article. The present disclosure also provides a dunnage bag with such valve.
摘要:
A rolled sheet-material supply handling-system that comprises a drawing device that can be configured to draw sheet material from a supply station and a stabilizer at the supply station. The stabilizer can define a generally tubular roll-receiving space in which a roll of the sheet material can be received and can have a support surface that can define an axial opening leading from the roll-receiving space to receive the sheet material drawn therefrom by the drawing device. The support surface can be sufficiently extensive to stabilize the outer layer of a roll against collapsing when the remainder of the roll has been extracted from the axial opening.
摘要:
A dunnage conversion system includes a machine for converting a stock material into a strip of relatively lower-density dunnage, a coiling mechanism for winding the strip into a coil, a taping mechanism for automatically securing a trailing end of the strip to the coil, and a coil ejecting mechanism for automatically removing the coil from the coiling mechanism. The taping mechanism includes a guide surface between an outlet of the machine and the coiling mechanism to guide the strip to the coiling mechanism and to guide tape for engagement with a trailing end of the strip and to secure the trailing end of the strip to the coil. The coil ejecting mechanism includes a lever arm that pivots to push the completed coil off the coiling mechanism.
摘要:
A dunnage conversion system (20) for making a coil of dunnage (24) from a sheet stock (22, 23) includes a coiler (30), a movable dancer (32) upstream of the coiler (30) and interposed in a path of the sheet stock, and a controller (34) communicatively coupled to each of the coiler (30) and the movable dancer (32). The coiler is configured to wind the sheet stock (22, 23), and the controller is configured to control the speed of the coiler (30) based on the position of the movable dancer (32) to control tension of the sheet stock (22, 23) upstream of the coiler. The sheet stock drawn about the movable dancer (32) may be a slit-sheet stock having a plurality of slits configured to expand under tension applied in a feed direction. The controller (34) may be configured to control expansion of the slit-sheet stock upstream of the coiler allowing conversion of the sheet stock into a coil (24) of relatively less dense dunnage prior to or during winding.
