A composite belt assembly for a band sealer is provided. The composite belt assembly comprises a belt comprising a main belt; a first layer; and a second layer; wherein the first layer is arranged in contact with the main belt, preferably between the second layer and the main belt; and the first layer includes an attachment portion, configured to contact the main belt and the second layer. There is also provided a band sealer comprising a composite belt assembly and a packaging line comprising the band sealer. There is further provided a method for heat sealing a package, comprising providing a composite belt assembly, gripping a bag neck of the package using the composite belt assembly, guiding the bag neck of the package along a movement plane using the composite belt assembly providing a sealing element configured for heat sealing a plastic material of the bag neck, and applying heat to at least part of the bag neck through the first layer of the composite belt assembly using the sealing element.

A method for brazing is provided, in which an amorphous or partially amorphous brazing foil, having a composition with a metalloid content of 10 to 30 at. %, is arranged at a joining point of two or more parts. The brazing foil is in the form of a wound ring-shaped strip which has a short-circuited current path between at least two layers lying one on top of the other. The brazing foil inductively heated, melted and a brazed connection of the parts is produced.

In order to achieve high product quality and process reliability in a process for manufacturing an endless profile strand of soft plastic and/or rubber material fed to a supply storage for a sealing profile, edge protection profile or the like on a motor vehicle, it is provided that the manufacturing process be divided into two process sections which are carried out on two manufacturing lines that can be operated independently of one another.

Disclosed is a method for assembling a wind turbine blade comprising a first blade component, e.g. a first blade half shell, and a second blade component, e.g. a second blade half shell, the first blade component comprising a first contact area configured to be connected to a second contact area of the second blade component, the first contact area having a first contact surface, the second contact area having a second contact surface.

A method for setting up a joining apparatus for joining a light lens to a housing of a motor vehicle lighting arrangement. A first virtual model is created of the joining apparatus with a light lens and a housing received therein, a relative arrangement of the light lens to the housing corresponds to a target arrangement. A plurality of virtual models are created of the joining apparatus with the light lens and the housing received therein. The relative arrangement of the light lens to the housing deviates from the target arrangement in each case by means of virtual displacement of the adjuster. A target displacement is calculated of an adjuster on the basis of a functional relationship calculated and the relative arrangement in the test construction unit measured. A light lens is joined to a housing in the target arrangement by displacing the adjuster by the target displacement.

A window manufacturing method includes providing a first adhesive on a dummy substrate, providing a first mother substrate on the first adhesive, disposing a first portion of an interleaving paper on a surface of a suction stage disposed on the first mother substrate, the surface of the suction stage facing the first mother substrate, and pressing the suction stage toward the first mother substrate to attach the first mother substrate to the dummy substrate.

A method of making a modular wind turbine blade is described. The modular blade comprises first and second blade modules connected together by a scarf joint between tapered spar caps of the respective blade modules. According to the method, first and second blade modules are laid up in the same mould assembly. A separating layer is arranged between the layups of the first and second module in a joint region of the mould. The separating layer has a thickness corresponding to a required bond thickness in the scarf joint when the modules are bonded together.

The present disclosure is directed to a compression belt for inflation and sealing devices. The device may include an inflation assembly, a heating assembly, and a drive mechanism. The inflation assembly may direct fluid between first and second overlapping plies of a flexible web material to inflate chambers between the plies. The heating assembly may be operable to heat the first and second plies of the web material to create a longitudinal heat seal that seals the fluid in the inflated chambers. The drive mechanism may drive the web material in a downstream direction. The drive mechanism may tension the web material against the heating assembly. The drive mechanism may include a first belt including a high grip material on a surface that contacts the web material to grip the web material during heating by the heating assembly.

A rotary device for welding a continuous web includes a rotary element, support elements for supporting the web, supported by the rotary element, and a plurality of welding units for welding the web. Each welding unit passes from a non-operating position to an operating position and vice versa, and includes a first movement device for commanding a relative rotation of an anvil element relative to a welding tip and a second movement device for moving the anvil element relative to the welding tip such that a contact surface of the anvil element and a contact surface of the welding tip make contact with a portion of the web in a zone between them, and vice versa. First and second drive mechanisms drive the first and second movement devices. The first and second drive mechanisms are configured to vary a positioning of the welding tip relative to the axis.
