A method of applying a sealing strip onto a web of packaging material comprising advancing the web along a web advancement path; applying a first longitudinal portion of the sealing strip onto a longitudinal edge of the web, sealing the first longitudinal portion of the sealing strip onto the longitudinal edge, detecting and/or determining a correct alignment of the sealing strip with respect to the web. The detecting and/or determining of the correct alignment comprises acquiring an image of a second longitudinal portion of the sealing strip and a reference marker of a strip application apparatus, analyzing the acquired image to determine at least a first transversal distance between the reference marker and a longitudinal border of the second longitudinal portion; and evaluating the correct alignment/misalignment as a function of at least the first transversal distance.

An eversion liner for lining a pipe includes an impermeable outer portion, inner and outer strength portions inside the impermeable outer portion, and a middle portion including at least one felt layer radially between the inner and outer strength portions. At least one of the inner and outer strength portions is formed from a unitary sheet of strength material that includes parallel chopped strands of fiber. The longitudinal edge margins of the sheet of strength material are positioned in overlapping engagement and joined together by joining structure. The parallel chopped fibers can be oriented transverse to the length of the liner. The joining structure can prevent reduction in a width of the overlapped edge margins as the liner expands during eversion.

The present invention relates generally to coated abrasive articles, such as coated abrasive film belts having improved strength and durability, as well as methods of making and using said coated abrasive articles.

A tank (e.g., an underground storage tank), and manufacturing methods therefore, may include a tank body having an exterior surface. A component is mounted on at least a non-planar portion of the exterior surface of the tank body using an adhesive (e.g., an MMA adhesive). For example, the component may be positioned on the non-planar portion of the exterior surface of the tank body after application of adhesive and pressure may be applied to maintain the position of the component on the non-planar portion of the exterior surface of the tank body as the adhesive is cured. The pressure may be removed upon curing of the adhesive and formation of a structural bond may occur at the adhesive interface between the mounting surface of the component and the non-planar portion of the exterior surface of the tank body.

A method for fabricating wetsuit garment including wetsuits, boots and gloves for water sports uses, comprising preparation of at least a high-elasticity joining member made of hot melt adhesive, and joining at least two interconnected panels of rubber foam or sponge by the high-elasticity joining member to cover and seal the seam between the two interconnected panels for firmly bonding the two interconnected panels for making a strong, elastic and flexible wetsuit garment.

The present invention provides a movable load bearing structure with a surface that includes antimicrobial agents capable of eliminating, preventing, retarding or minimizing the growth of microbes and also minimizing cross-contamination when the load bearing structure is being reused for cargoes that differ from a previously transported cargo, for example, different food types, such as poultry, fresh vegetables, and fresh fruit. The load bearing structure may be a dunnage platform or a container for storing and/or shipping cargo.

Disclosed herein are methods, devices, and systems for manufacturing wind turbine blades which in some instances require using new blade joint designs. The blade joint designs described herein may allow for contact in places where welds will be made, which allows for existing manufacturing tolerances to be used while still enabling the use of thermal welding for wind turbine blades.

A method of making a storage bag comprising the following steps performed in any order: (a) forming a composite tube having an inner surface comprising a higher melting polymer, an outer surface comprising a lower melting polymer, two ends, and a diameter; (b) flattening the tube in a direction perpendicular to the diameter; (c) forming a joint at one of the ends at a temperature between respective melting points of the higher melting polymer and the lower melting polymer; (d) providing a composite sheet having a first side comprising a higher melting polymer and a second side comprising a lower melting polymer; and (e) disposing the composite sheet over the joint such that the first side comprising a lower melting polymer engages the joint and forming a lap seam over the joint at a temperature between respective melting points of the higher melting polymer and the lower melting polymer, and a storage bag made by such method.

A relatively thick, rubberized adhesive tape is applied to an article to repair, patch, bond, seal, or waterproof the article, to join two or more articles, and/or to modify the appearance and/or physical properties of the article, such as by thermal insulation, shock resistance, vibration resistance, electrical insulation, and the like.

An assembly, configured in particular in the form of an aircraft assembly, comprises a plurality of individual components composed of a fibre-reinforced composite material. An edge section of at least one individual component is sealed by means of a sealing tape which contains reinforcing fibres and a curable plastics material.
