A process is provided for making stiff, lightweight laminate materials. At least one sheet of textured lamina having raised pointed structures is forced against a softer plain lamina so as to embed the structures therein. The pointed structures raised from grooves carved into the surface of the sheet material by means of a set of teeth carried on a knife element. The pointed structures may pierce through the softer lamina such that the protruding tips may be bent over or clinched to prevent their easy withdrawal. Two such texturized lamina may be used to sandwich and pierce through the softer lamina and are co-clinched by the other. In this way a light and stiff laminate is created.

Disclosed is a fibrous web having a first region and at least one discrete integral second region, the second region having at least one portion being a discontinuity exhibiting a linear orientation and defining a longitudinal axis, and at least another portion being a deformation having a plurality of tufted fibers integral with but extending from the first region.

A breathable and waterproof composite fabric includes a fabric sheet and a waterproof plastic film. The fabric sheet has a first surface, a second surface and a plurality of micropores extending through the first and second surfaces. The waterproof plastic film is made of a non-porous material and has an outer surface, an inner surface bonded to the first surface, and a plurality of hollow protrusions protruding from the outer surface. Each of the hollow protrusions defines a channel having an inner open end at the inner surface and an outer open end distal from the inner and outer surfaces. A method of making the breathable and waterproof composite fabric is also provided.

A housing for an electronic device as well as methods for forming the housing are disclosed. The housing can be formed from a substrate having perforations to assist in adhering components internal to the housing. The substrate is typically a multi-layer substrate having at least two layers. In one embodiment, an inner layer of the multi-layer substrate can be provided with perforations. The perforations can them be used to adhere internal features to the multi-layer substrate. The internal features can be used for attaching parts or components to the multi-layer substrate, thereby securing the parts or components to the multi-layer substrate and thus the housing.

A nonwoven industrial fabric comprising a first layer secured to a second layer, with each layer comprising a plurality of flow-through apertures and profiling protrusions, wherein: a) at least a portion of the flow-through apertures of the first layer is aligned with at least a portion of the flow-through apertures of the second layer; b) the first layer comprises a plurality of securing protrusions integral to the first layer; c) the second layer comprises a plurality of detents integral to the second layer; and d) the first layer is secured to the second layer by a plurality of locking pairs, each locking pair comprising a securing protrusion lockably engaged with a detent. A method of making the nonwoven industrial fabric is also described.

The present invention relates to the display technology field, and provides a backplate, a plastic-iron integrated structure, a backlight unit, and a display device. The backplate is provided with a first through hole, and the first through hole has an inner wall and an outer wall which form a projection structure on the backplate. When the backplate is bonded with a plastic frame to form the plastic-iron integrated structure, the plastic frame not only contacts the inner wall of the first through hole, but also contacts the surface of the projection structure, thus increasing the contact area between the plastic frame and the backplate, and increasing the bonding force between the plastic frame and the backplate. Even when the plastic frame shrinks in case of fluctuations in temperature and/or humidity, the plastic frame is not easily separated from the backplate, and the stability of the formed plastic-iron integrated structure is improved.

A patterned fabric with an image pattern includes: a fabric sheet having opposite first and second surfaces and a plurality of pores extending through the first and second surfaces, each of the pores being defined by a pore-defining wall; and a plastic film bonded to the first surface of the fabric sheet and having opposite first and second faces and an image pattern formed on the first face. The plastic film is perforated to form a plurality of through-holes extending through the first and second faces. Each of the through-holes is defined by a hole-defining wall. The hole-defining wall of each of the through-holes extends into a respective one of the pores and wraps around and is bonded to at least a portion of the pore-defining wall of the respective one of the pores.

This application relates to a light-weight, multi-purpose construction panel. The panel may be formed, for example, from molded plastic. Each panel includes a substantially planar deck on a first side thereof and a second side comprising alternating male and female sleeves arranged in honeycomb-like compartments defined by a plurality of wall elements. A pair of panels may be releasably coupled together with their respective second sides facing inwardly to form a construction assembly. When a pair of panels is coupled together, the male sleeves of one panel matingly fit within the females sleeves of the other panel, and vice versa. The panel assemblies may be used for many different construction applications including flooring, roofing and wall structures.

The invention relates to the packaging of one or more articles in a packaging sheet material which is moveable from a first condition to a second, expanded, condition to improve the packaging effect of the sheet material. In accordance with the invention the sheet material includes a first portion with apertures which can be moved to an open position to create the second, expanded, condition and at least one, but typically a plurality of spaced apart, second portions which have no apertures, or a different shape and/or pattern of apertures than the apertures of the first portion, so as to form a surface of the said second portion more suitable for the application of a label and/or indications thereon when the sheet material is in the second expanded condition.

A laminate web having a polymer film layer and a nonwoven layer is disclosed. The polymer film layer makes up a first side of the laminate web and the nonwoven layer makes up a second side of the laminate web. The laminate web has a plurality of first elements extending from the polymer film. The web also has a plurality of second elements such as recesses, protrusions, apertures, embossing and combinations thereof.
