Expanded slit sheet cushioning products with novel reduced dimension slit patterns
In the preferred embodiments, the present invention provides substantially improved slit sheet cushioning products by advantageously combining novel paper properties with novel slit patterns for improved features and characteristics. In some illustrative and non-limiting example embodiments, cushioning products of the present invention can include, e.g., a novel slit sheet material in combination with extensible paper employed as, e.g., a cushioning pad or as cushioning within an envelope product, wherein the cushioning product can be substantially more resilient, but, yet, e.g., thinner for better utilization of space.
EMBOSSED PAPER IN COMBINATION WITH PAPER CUSHIONING FOR SHIPPING ENVELOPES
According to some illustrative embodiments, a protective product is provided that includes: at least one expandable slit paper sheet, said at least on expandable slit paper being expanded between opposing ends of said slit paper; a first embossed paper sheet facing said expanded slit paper sheet and a second paper sheet facing an opposite side of said at least one expanded slit paper sheet, at least one of said first embossed paper sheet and said second paper sheet being fixed to said expanded slit paper sheet at the opposing ends of said expanded slit paper sheet and thereby maintaining said expanded paper in its expanded state, said first embossed paper sheet having a plurality of embossings that increase the rigidity of said embossed paper sheet, whereby inhibiting deformation of said embossed paper sheet that is fixed to said expanded slit sheet paper.
Coiler for a dunnage conversion machine and method for coiling a strip of dunnage
A coiler for producing tighter or smaller coils of dunnage uses a cam to move fork pins from a dunnage-receiving position inwardly to a more closely-spaced coiling position. The fork pins are coupled to pin mounts that cooperate with the cam and slots in a guide plate to move the parallel fork pins between the dunnage-receiving and coiling positions. The fork pins are mounted to extend perpendicular to and through the guide plate on opposing sides of a path of the dunnage to capture and wind a dunnage strip into a coil.
Packing material and method of manufacturing the packing material
A molded packing material and a method of making the molded packing material. The molded packing material includes a plurality of molded fiber cushioning elements. The molded packing may also include a matrix comprising cellulosic fibers bonding the plurality of molded fiber cushioning elements to each other. The plurality of molded fiber cushioning elements and matrix form a mass that has been molded into a shape having exterior surfaces and an interior with some of the plurality of molded fiber cushioning elements being on the exterior surfaces of the mass and the remainder of the plurality of molded fiber cushioning elements being in the interior of the mass. The molded packing material may also include a fiber shell having a cavity formed therein with the plurality of molded fiber cushioning elements located in the cavity.
EXTENSIBLE PAPER AND ITS USE IN THE PRODUCTION OF EXPANDED SLIT PACKAGING WRAP AND VOID FILL PRODUCTS
An extensible slit sheet paper product is produced having an expandable slit pattern that forms open cells upon expansion of the paper product. The paper product is an extensible paper having an extensibility in the range from 1-9% in the machine direction and 1-5% in the cross direction. The expansion produces an array of hexagonal cells. The expanded extensible paper can be used to wrap an object for shipping by wrapping and cushioning the object in the expanded slit sheet material. The extensible, expandable slit sheet paper can be wrapped around itself to produce a void fill product.
Method and apparatus for processing a length of padding material
In a method for processing a cushioning material strand, which is produced by a cushioning conversion machine from a web-shaped stock material (e.g. a roll or a leporello stack, for example of paper), the cushioning material strand is wound around a winding center into a cushioning material winding and is compressed during winding into the cushioning material winding.
Sheet packaging
Sheet packaging has a corrugated ply bonded to a backing ply. The corrugated ply forms parallel flutes. The packaging comprises voids through both the corrugated ply and the backing ply at intervals along the flutes, thereby forming a plurality of insular portions interconnected by flexures. Each insular portion has a flute portion and a backing portion between adjacent voids and bonded together at respective edges and each flexure comprises bonded-together portions of the corrugated ply and the backing ply. The flexures confer hyper flexibility to the packaging wherein each flexure possesses an independent bend axis across which the flexure can both be twisted and bent.

Embossed paper in combination with paper cushioning for shipping envelopes
According to some illustrative embodiments, a protective product is provided that includes: at least one expandable slit paper sheet, said at least on expandable slit paper being expanded between opposing ends of said slit paper; a first embossed paper sheet facing said expanded slit paper sheet and a second paper sheet facing an opposite side of said at least one expanded slit paper sheet, at least one of said first embossed paper sheet and said second paper sheet being fixed to said expanded slit paper sheet at the opposing ends of said expanded slit paper sheet and thereby maintaining said expanded paper in its expanded state, said first embossed paper sheet having a plurality of embossings that increase the rigidity of said embossed paper sheet, whereby inhibiting deformation of said embossed paper sheet that is fixed to said expanded slit sheet paper.
