A method of making a cleaning article. The cleaning article has discrete tufts of tow fibers. The discrete tufts are unequally spaced from adjacent tufts, to provide improved collection and retention of debris from a target surface. The cleaning article may be made by cutting out spaces between tufts from a precursor sheet. Optionally the precursor sheet may be attached to a carrier sheet.

A method of forming a laminate countertop with a curved edge profile extending around at least two adjacent sides thereof includes providing a base support having a top surface, a bottom surface, latitudinal sides, and longitudinal sides. At least one of the longitudinal sides includes the curved edge profile. The method further includes: adhering a laminate sheet to the base support to form a laminate cover over at least a portion of the top surface and a portion of the curved edge profile of the base support and mounting a preformed edge member having a curved edge profile to one of the sides of the base support to form a laminate countertop having curved edges extending around at least two sides thereof. To align the edge member and the base support, the preformed edge member is mounted to a brace to remove bowing or curvature from the preformed edge member.

A sealing tape roll which comprises barrier layers extending in the radial direction that are arranged axially between layers of foam and consist of a sealing element wound up into the sealing tape roll. The sealing element includes at least three sealing tape sections which are arranged next to each other in a functional direction of the sealing element. First and second barrier layer sections are each arranged between two adjacent sealing tape sections and parallel to the side surfaces of the sealing element. The first and second barrier layer sections each comprise two legs connected to each other. The legs of the first barrier layer section are connected to each other in an area of the bottom surface of the sealing element and the legs of the second barrier layer section are connected to each other in an area of the top surface of the sealing element.

A sealing element of flexible foam which includes at least three sealing tape sections which are arranged next to each other in a functional direction of the sealing element. At least one first barrier layer section and at least one second barrier layer section are each accommodated between two adjacent sealing tape sections. The barrier layer sections connect the adjacent sealing tape sections to each other. The first barrier layer section forms a loop in an area of the bottom surface of the sealing element and the second barrier layer section forms a loop in an area of the top surface of the sealing element.

A method for the production of a sealing tape roll of flexible, compressible foam with at least one barrier layer extending in the radial direction, which is arranged axially between two layers of foam. The method includes providing a foam web of a flexible foam; applying a first barrier layer to a first surface of the foam web; and introducing at least one first cut into the first surface of the foam web and introducing at least one second cut into a second surface of the foam web opposite the first surface to form parallel sealing tape strips. A connecting section remains between two adjacent sealing tape strips. The sealing tape strips are then folded over in the area of the connecting sections to produce a foam-barrier layer web, and the foam-barrier layer web is wound up into a sealing tape roll.

A method of making an aircraft acoustic structural panel (10) begins with preforming a core honeycomb laminate (12) having preformed foam (3) bonded inside cells (14) thereof by a distinct adhesive (2). The preformed honeycomb laminate (12) is then stacked between opposite top and bottom structural outer laminates (16,18). The stacked honeycomb laminate (12) and outer structural laminates (16,18) are then compressed together under heat and pressure into a unitary structural panel (10) having the core honeycomb laminate (12) integrally bonded between outer skins (20,22). The outer laminates (16,18) may include imperforate acoustic septums (4) bounding the core honeycomb laminate (12) followed by an outer honeycomb (5) and structural fiber layers (6,7,8) defining the outer skins (20,22).

Provided are an electroacoustic conversion film web, an electroacoustic conversion film, and a method of manufacturing an electroacoustic conversion film web in which costs can be reduced by reducing the number of operations without damage to thin film electrodes, the points of electrode lead-out portions can be freely determined, and thus high productivity can be achieved. A preparation step of preparing an electrode laminated body in which a single thin film electrode and a single protective layer are laminated and a lamination step of laminating the electrode laminated body and an piezoelectric layer are included. A non-adhered portion that is not adhered to the piezoelectric layer is provided in at least one end portion of the thin film electrode in a case where the electrode laminated body and the piezoelectric layer are laminated in the lamination step.

An expansion joint seal proving a flexible barrier therethrough in a concave shape with a first body of compressible foam on one side and a second body of compressible foam on the other side, where the barrier extends laterally from the first body and second body and may be used to protect the sides of the expansion joint seal or may be used to provide contact on the surface of each adjacent substrate.

A method of producing a sandwich panel core of mineral wool fibers from a cured mineral fiber product includes the steps of providing a cured mineral fiber product with a dual density having a top layer with mineral fibers with a first density and a base layer having mineral fibers with a second density, the second density is at least two times lower than said first density. The top layer and the base layer have different fiber orientations. Further steps including cutting the mineral fiber product into a plurality of lamellae, rotating the lamellae 90 degrees, and re-joining the lamellae so that the top layers with the first density are vertically oriented.

A weight applicator system includes a shaft, an applicator assembly, and a weight feed assembly. The shaft defines a length between a proximal end and a distal end configured to support a wheel-tire assembly for common rotation about a longitudinal axis of the shaft. The applicator assembly is supported by the shaft and includes a base portion disposed upon the shaft and operable to translate axially along the length of the shaft, a radial portion connected to the base portion and operable to radially move relative to the base portion between a retracted position and an extended position; and a pressure roller rotatably supported by the radial portion about an axis of rotation. The weight feed assembly is operable to feed a prescribed length of weighted material to the pressure roller.
