An applicator (200), for applying a glutinous substance (140) to a seam (330) between a first part (310) and a second part (320), comprises a roller (210), comprising a circumferential surface (216), and a housing (220), comprising a delivery port (222), a scraper (232), and a shaper (234). The roller (210) is coupled to the housing (220) and is rotatable relative to the housing (220) about an axis (202). The circumferential surface (216) of the roller (210) is communicatively coupled with the delivery port (222). The intersection of the circumferential surface (216) and a virtual plane, passing through the axis (202), is a non-linear segment (217). The scraper (232) is geometrically complementary at least with the non-linear segment. The shaper (234) is communicatively coupled with the scraper (232).

A piece of substrate material is formed under heat and pressure by a roller against a cavity or platen into a shaped substrate sheet having one or more depressions. Two substrate sheets are bonded together to form a substrate wherein the one or more depressions form one or more interior channels. The substrate is coated with a dope in a casting device having a guide portion corresponding to the shape of the substrate sheets and quenched to form a filtering membrane.

Method of attaching a lining 1 to an interior surface 10 of a room comprising the steps of: providing a first sheet of lining 1 to be applied to the interior surface 10; applying a plurality of glue dots 2 to the interior surface 10 or to the first sheet of lining 1; and attaching the first sheet of the lining 1 to the interior surface 10 such that the first sheet of lining 1 is fixed to the interior surface 10 via the glue dots.

The present disclosure is directed to methods for joining rotor blade components using thermoplastic welding. The method includes arranging a first thermoplastic component and a second thermoplastic component together at an interface, determining a size of a tolerance gap between the first and second components at the interface, placing a thermoplastic insert between the first and second components at the interface, the insert being larger than the tolerance gap, heating the insert and the first and second components such that the insert begins to flow so as to fill the tolerance gap between the first and second components, applying pressure to the interface such that the insert and the first and second blade components remain substantially in direct contact with each other at the interface, and welding the insert and the first and second components together at the interface, wherein the heat and the applied pressure between the insert and the first and second components at the interface maintain the insert and the first and second substantially in direct contact at the interface during welding.

The present invention can combine fabrics in a seamless manner by forming at least one bonding pattern line by a process comprising: printing and drying a heat-reactive adhesive on the inner surface of an inner fabric, and/or an outer fabric or an optional mesh material in a predetermined pattern, laminating said inner fabric, optional reinforced material and outer fabric, and then high-frequency heating them under pressing with a pressing pattern the same as the printing pattern to bond the inner fabric, and outer fabric.

Since the present invention combines fabrics by employing a high-frequency bonding manner in which a heat-reactive adhesive is used, it is possible to combine fabrics in a seamless manner with a bonding pattern line which is composed of a bonding line with excellent adhesiveness and durability and an aesthetically excellent pattern line with a good clearness and finishing quality.

A patch may be used to rework a composite structure in the field. The patch is bonded to the structure by a layer of adhesive and includes perforations that allow the escape of air from the adhesive as the patch is compressed against the structure. A spacer may be introduced between the patch and the structure to control the thickness of the adhesive layer.

The present invention relates to alternative methods of joining a solid part (1) and a polymer (2). The methods comprise attaching a primer layer (4) with a predetermined surface chemistry, density and thickness covalently to at least a part of a surface (3) of the solid part (1). Some embodiments of the invention further comprise polymerizing second molecules onto the primer layer (4) so that the surface (3) is at least partly covered with surface immobilized polymer brushes (8). The surface (3) of the solid part (1) is brought into contact with the polymer (2) and a predetermined temperature profile is applied resulting in covalent bonds (6) being established between the polymer (2) and the primer (4), and/or polymer brushes (8) melting or softening and entangling with melted or softened polymer (2) so that the solid part (1) and the polymer (2) remain joined after cooling. The obtained strength of the bonding between the solid part (1) and the polymer (2) is significantly higher than if the same materials are joined with conventional methods not comprising the establishment of a primer layer (4).

The present invention provides a labelling apparatus for applying labels to containers, comprising a gluing device having a glue roller and a glue-application unit, which is assigned to the glue roller and is intended for applying glue to the glue roller, wherein the glue-application unit has at least one accommodating space for accommodating the glue, and wherein the glue roller and/or the glue-application unit are designed, and arranged in relation to one another, such that glue which is located in the accommodating space is applied to the surface of the glue roller only in one or more sub-regions of the overall extentas seen in the axial direction of the glue rollerof the surface of the glue roller.

An adhesive (B) of solvent containing adhesive as a suspension of low viscosity is prepared by adding a solvent MIBK to a one-part epoxy adhesive of a dicyandiamide-curable type (A). Metal shaped articles (M1 to M5) as adherends are prepared each of which, through various surface treatment, has specific surface configuration of roughened face and/or ultrafine irregularities and the surface is entirely covered with a thin layer of ceramics such as a metal oxide or metal phosphate. The specified face of each metal shaped article (M1 to M5) is painted with the solvent containing adhesive (B). The faces painted with the adhesive of two metal shaped articles (M1 to M5) are caused to abut each other, the articles are heated to cure the one-epoxy adhesive to accomplish adhesion. With one of the adherends replaced by a CFRP shaped article (P2), a composite of a metal and CFRP can be formed.

A foam assembly system is provided. The system is configured to heat a surface of foam. After the heating of the foam, an adhesive is applied, typically a high solids adhesive. The foam is then bonded to another foam surface. It has been found that the pre-heating of the foam before adhesive application greatly enhances the bond strength between the foam and the second foam surface to which it is adhered.
