Improvements relating to wind turbine blade manufacture 5 A method of making a wind turbine blade is described. The method involves providing a blade shell having an inner surface defining a mounting region and positioning a web in the mounting region. One or more web restraining devices are used to secure the position of the web in the mounting region. Each restraining device has a first portion attached to the web and a second portion attached to the inner surface of the blade shell. The 10 restraining devices are configured to prevent movement of the web in a first plane substantially parallel to the mounting region and to permit movement of the web in a second plane substantially perpendicular to the mounting region. The method further comprises moving the web in the second plane away from the mounting region and performing one or more preparatory operations on the mounting region with the web 15 moved away from the mounting region. The web is then repositioned in the mounting region by moving the web in the second plane back towards the mounting region.

A wind turbine blade and associated method of manufacture is described. The blade comprises an outer shell formed of first and second half shells joined together. A shear web is arranged inside the outer shell. The shear web has a web panel disposed between first and second longitudinally-extending mounting flanges. The shear web is bonded to inner surfaces of the respective half shells via a first adhesive bond line between the first mounting flange and the inner surface of the first half shell and a second adhesive bond line between the second mounting flange and the inner surface of the second half shell. One or more bond spacers are provided in the second bond line, and optionally in the first bond line. The bond spacers are compressed between a shear web mounting flange and an inner surface of a half shell and are plastically deformed. The method of making the shear web involves compressing and the one or bond spacers in the bond line(s) such that they undergo plastic deformation. This results in high quality bond lines.

A method of forming a non-pneumatic tire is provided that includes the steps of providing an outer shear band ring (12), and an intermediate section (14) that has a supporting structure with an attachment tab (46). The intermediate section (14) is inserted inside of and engages the outer shear band ring (12). A hub (20) is provided that has an attachment tab receiving feature (48), and the attachment tab (46) is received by the attachment tab receiving feature (48). The supporting structure is attached to the hub (20) by an ultrasonic process applied to the attachment tab (46).

The invention relates to a vibration welding system (10) for vibration welding two parts (50, 60) together, in particular two plastic parts (50, 60). The system (10) comprises a machine frame, a lower tooling (12) to which at least a lower part (50) is nestable, as well as an upper tooling (13) which is arranged to be brought into contact with an upper surface (65) of an upper part (60) and to vibrate with respect to the machine frame in a vibration direction (X) in order to at least partially weld a lower surface (61) of the upper part (60) to an upper surface (51) of the lower part (50). The lower tooling (12) is pivotably arranged with respect to the machine frame about a pivot axis (P). The invention further relates to a vibration welding method for vibration welding two parts (50, 60) together and to a method of upgrading an existing vibration welding system to a vibration welding system (10) according to the invention.

A venting apparatus (100) is disclosed herein. The venting apparatus comprises a substrate (102), such as a metal substrate or a specialty plastic substrate, having an opening (104) therein and a fluoropolymer membrane (106), such as ePTFE, disposed over said opening and thermally bonded using a thermoplastic material (110) to said substrate. This allows the fluoropolymer membrane to be directly bonded to the said substrate without using an adhesive layer.

摘要:
A welded shoe assembly includes a shoe upper with a plastic surface welded to a plastic surface of a bottom unit. The welded shoe assembly is formed, in one implementation, by compressing the shoe upper and a bottom unit against one another between an electrically conductive last and an electrically conductive mold and applying an electrical signal to either the electrically conductive last and/or the electrically conductive mold.
