EXPANDED SLIT SHEET CUSHIONING PRODUCTS WITH NOVEL SLIT PATTERN AND PAPER PROPERTIES
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.

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.

Creping blade and method for manufacturing same
A creping blade and a preparation method thereof are provided. The creping blade comprises a base, wherein a wear-resistant coating is provided on the top of the base, and a protective layer is arranged below the wear-resistant coating at the contact point between the creping blade and a dryer, and the hardness of the protective layer is lower than that of the surface of the dryer of a paper machine. The creping blade of the invention is advantageous in that the friction portion of working surface has an unlimited area and has a high wear-resistant coating, and the paper impact portion has high wear resistance and high impact resistance, so that the creping blade has a long service life, which can be several times or even tens of times that of the common steel creping blade.
Honeycomb structure
A honeycomb structure has partition walls defining a plurality of hexagonal cells the partition walls are constituted by combining standard partition walls having a partition wall thickness in a range smaller than 10% to an average partition wall thickness of the partition walls, wide partition walls having a partition wall thickness of +10% or more to the average partition wall thickness, and narrow partition walls having a partition wall thickness of 10% or less to the average partition wall thickness, and a non-standard partition wall ratio is in a range of 10% to 30% which is a ratio occupied by a subtotal number of non-standard partition walls obtained by adding the wide partition walls and the narrow partition walls in a total number of the partition walls which is obtained by adding the numbers of the standard partition walls, the wide partition walls and the narrow partition walls.
PALLET HAVING PANELS AND TUBE SEGMENTS
The invention relates to a pallet (1), comprising a basic body (10) with a first panel (11), a second panel (12) and a layer (13) having a plurality of tube segments (14) which is arranged between the panels (11, 12), wherein the layer (13) has at least one cutout (131) which is continuous in the direction of a pallet height (HP), and wherein the first panel (11) has at least one first opening (111) which at least partially overlaps with the at least one cutout (131). The invention further relates to a foot (16) and a runner (17) for a pallet (1), to a sandwich block (2) for producing a layer (13) of a pallet (1), and to a method for producing a pallet (1).
Tooling method for expanded slit sheet material
The present invention discloses a method of producing at least a pair of interlocking adjacent layers of a paper packaging product, the pair of interlocking adjacent layers being formed of a sheet of slit paper having a slit pattern, the slit pattern upon expansion, forming cells that include land regions that are inclined with respect to a plane of an unexpanded sheet. The method comprises slitting the sheet of slit paper with beveled blades that have a first wedge angle on one side of the blades and a second wedge angle on the other side of the blades, wherein the first wedge angle is wider than the second wedge angle to produce slits that upon expansion, produce the lands regions that have angles of inclination in a range for 50 to 85 degrees.
