Patterned apertured webs are provided. The patterned apertured webs include a plurality of land areas and a plurality of apertures defined in the patterned apertured webs. At least some land areas of the plurality of land areas surround at least some apertures of the plurality of apertures. The patterned apertured webs have an Effective Open Area in the range of about 3% to about 30%, according to the Aperture Test.

This insulating panel for an insulated air-flow casing comprises an inner sheet forming an inner wall, an outer sheet fastened to the inner sheet and forming an outer wall, a layer of insulating material placed between the inner and outer sheets, and a peripheral edge extending transversally between the inner wall and the outer wall. The peripheral edge comprises at least a first and a second rows of perforations, and the perforations of the second row are placed with respect to the first row of perforations in a staggered manner.

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.

A method of producing a veneered element (10), including providing a substrate (1), applying a sub-layer (2) on a surface of the substrate (1), applying a veneer layer (3) on the sub-layer (2), and applying pressure to the veneer layer (3) and/or the substrate (1), such that at least a portion of the sub-layer (2) permeates through the veneer layer (3). Also, such a veneered element (10).

The present invention is transportable economically in a flat state, and easy to attach and detach, and can provide a curved surface simply while maintaining decoration and strength without craftsmanship and absorb sound. Slits are provided on a rectangular board panel comprising two or more layers of a hard material and a soft material. Two or more layers comprising a hard material and a soft material are laminated on a rectangular board panel, and slits having a length of ½ to ¾ of the vertical side are provided thereto. The use of slits makes formation of curved surfaces easy. Since there is no need to reinforce the outside to maintain the strength thereof, the board panel can be removed easily. Even if an external pressure is applied to the board panel, the flexibility of the hard material divided by the slits and the elastic characteristic of the soft material cause the pressure to be dispersed and absorbed, and sound to be absorbed.

The present disclosure relates to a support substrate for a flexible display device, and a flexible display device, the support substrate comprises a bending area, a transition area, and a non-bending area, wherein the transition area is located between the bending area and the non-bending area, the bending area has a plurality of first through holes and the transition area has a plurality of second through holes, wherein an area ratio of the plurality of first through holes in the bending area is greater than an area ratio of the plurality of second through holes in the transition area.

A composite pane with an electrical load, includes an outer pane and an inner pane that are joined to one another via a thermoplastic intermediate layer, wherein the thermoplastic intermediate layer has a recess that has a receiving opening, the receiving opening is dimensioned such that it is designed for accommodating the electrical load in the recess, and the electrical load is arranged in the recess.

An improved expandable slit-sheet stock material is configured to aid in temporarily restricting opening of a plurality of slits of the slit-sheet stock material, such as during winding of the unexpanded stock material or during expansion of the stock material. Each slit of the plurality of slits includes one or more un-slit reinforcement portions, such as reinforcement ties, extending fully between opposite longitudinal sides of the slit, and disposed between opposed transverse endpoints of the slit. The reinforcement ties minimize or prevent tearing of the stock material during the winding or expansion. A dunnage conversion system for expanding the slit-sheet stock material includes an expander having a pair of opposed rollers. The rollers engage the stock material to effect breaking of the un-slit reinforcement portions and expansion of the slit-sheet stock material.

A patterned apertured web includes a plurality of first arrays forming a first zone in the patterned apertured web. At least some of the first arrays include a first plurality of land areas and a first plurality of apertures. At least some of the first plurality of land areas surround at least some of the first plurality of apertures. The first plurality of apertures of the first zone have a plurality of Interaperture Distances, according to the Aperture Test. The Interaperture Distances of the first zone have a first distribution having a first mean and a first median. The first mean is greater than the first median by at least 4%.

Described are thermoplastic composite parts (30, 110) made up of resin-based fiber composites for use in aircraft furnishings. The thermoplastic composite parts (30, 110) can be formed into various shapes including bends so as to be suitable for replacing heavier sheet-metal components (100), particularly in aircraft furnishings.
