A novel engineered wood product and method of making same that withstands the stresses, both natural and man-made, that cause warp, twist and bow.

The invention relates to a double-layer wood engineered floor and method for making the same. The double-layer wood engineered floor comprises a plurality of front boards and a plurality of backboards, and each of the front board and each of the backboard are pasted together through an adhesive layer to form a double-layer wood structure. The double-layer wood engineered floor reduces the number of adhesive layers, that is, only one adhesive layer is used, which reduces the emission of harmful gases. The special structure of the backboard, that is, the horizontal and vertical staggered wood grain direction, greatly improves the structural stability of the double-layer wood engineered floor. It solves the problem that the other double-layer wood engineered floor has poor deformation resistance, and the problem that the traditional three-layer or multi-layer wood engineered floor has many adhesive layers, which releases excessive harmful gases.

A support for installing facing materials such as ceramic tiles on a substrate such as floors, walls and ceilings wherein the support plate has a plurality of spaced apart recesses in the plate material, with the recesses being open at the top surface and have solid sidewalls and a base, and a plurality of slots in the non-recessed portions of the plate material extending through the top surface and bottom surface, the slots joining one or more adjacent recesses. The support plate of the invention is used for tile installations between the substrate and such tile. Thin-set mortar that is used to secure the tile to the support plate flows into the recesses and into the slots forming a continuous bond between the mortar and the adjacent slots providing for a strong bond between the support plate, mortar and the tiles.

A method of making a tube (60) includes forming at least one tube layer (101, 106, 108); and forming at least one film layer (102, 103, 104) on the at least one tube layer, wherein the at least a portion of the at least one film layer does not completely overlap the at least one tube layer.

The present invention relates to a composite container comprising a bottom film layer and a top film layer at least partially adhered to the bottom film layer. The top film layer is scored to form at least one resealable flap and at least one pull tab which is not adhered to the bottom film layer. The bottom film layer comprises at least one cavity opening. A cardboard layer is adhered on its lower surface to the upper surface of the top film layer, wherein the cardboard layer has at least one cavity opening which is substantially aligned with the scoring of the top film layer resealable flap and the cardboard layer is perforated to define a perimeter of at least one pull tab which is substantially aligned with and adhered, on its underside, to the upper surface of the top film layer pull tab.

A method for making nonwoven fabric. The nonwoven fabric can include three-dimensional features that define a microzone comprising a first region and a second region. The first and second regions can have a difference in values for an intensive property. The nonwoven further has a plurality of apertures, wherein at least a portion of the aperture abuts at least one of the first region and the second region of the microzone.

A manufacturing system for laying up a stringer laminate includes a lamination surface and a plurality of lamination heads including a frame filler outer ply lamination head for laying up (e.g., laminating) frame filler bottom ply at a plurality of frame filler locations. Also included is at least one frame filler inner ply lamination head for laying up one or more frame filler inner plies over a protruding portion of the frame filler bottom ply at each frame filler location. Further included is at least one stringer body lamination head laying up one or more stringer body plies defining a stringer body portion extending along the lamination surface. A frame filler outer ply lamination head is configured to lay up a frame filler top ply at each frame filler location such that the frame filler inner plies are captured between a frame filler bottom ply and a frame filler top ply.

A dual roll laminating film cartridge includes a body defining a first end supporting first ends of first and second rolls of continuous translucent laminating film. The body further defines a second end supporting second ends of the first and second rolls, wherein facing surfaces of the films extended from the first and second rolls in an advancing direction are coated with a heat-activated adhesive. A bridge extends between the first and second ends of the body at a position between the first and second rolls, the bridge defining an article chute for the reception of articles to be laminated by the films of the first and second rolls. The cartridge further includes a code indicative of one or more characteristics of the film of the first and second rolls, the code comprising a predetermined flag pattern of coding tabs that project outward from the body.

A method for manufacturing structural rods to make it easier to manufacture a structural rod for an aircraft and to improve performance. Each rod includes a rod body and two end portions disposed at either end of the rod body along a longitudinal central rod axis, each end portion comprising at least one mounting lug that protrudes from the rod body along the longitudinal axis. The method includes producing a sandwich panel including two skins gripping a cellular inner body, at least one of the two outer skins having a skin extension for forming a part of the at least one mounting lug of at least one of the two end portions of the rod, and cutting the panel along parallel cutting lines to obtain the structural rods.

The present disclosure provides a plastic floor, and a production apparatus and a production process of the plastic floor. At least on or near one of its edges the plastic floor includes a chamfer formed during a rolling press and plate press forming process. During the rolling press and plate press forming process of the plastic floor of the present disclosure, a chamfer is formed at the periphery on the front surface of the plastic floor. The wear-resistant layer and color film layer at the chamfer are not damaged. When splicing, the chamfers on the two pieces of plastic floor are connected to each other to form a joint seam, and there is no need to cut and chamfer the edge of the floor before grooving, thereby reducing the production process, and improving the appearance of the joint seam.
