A preparation method of a polytetrafluoroethylene (PTFE)-based membrane for preventing and removing ices covering wind turbine blades is provided and the method comprises: preparing a membrane into a PTFE rod material with polymerized monomers by using monomer polymerization methods such as blending, pre-compressing and pushing; making the membrane into a PTFE-based homogeneous membrane with micropores and nano and micron scale concave-convex geometrical ultra-structure morphologies under the condition that the membrane is cracked to generate a laminar exfoliated fabric-like structure in the hot calendaring process of the PTFE rod material by using a hot calendaring and fusion polymerization method; and applying the PTFE-based homogeneous membrane to blades of a large wind turbine in operation.

The adhering device of the present application includes a chamber; a carrying platform having a groove formed thereon; a pressing block assembly for supporting the flexible display panel, and fitting the flexible display panel toward the curved cover plate at a preset rising speed; a clamp assembly for holding the flexible display panel, and when the flexible display panel is adhered to the curved cover plate at a preset ascending speed, the clamp assembly starts to rotate until the flexible display panel and the curved cover plate completely adhere together with the display panel separation.

A flat laminate element made of thermoplastic is hot-formed in a two-stage method. In a first stage, the flat laminate which includes film(s) and/or panels(n) is placed on a flat frame-shaped pallet and is heated to a forming temperature in a heating zone between two flat heat screens in a contactless manner. The edge zone of the hot flat laminate element lies on the pallet such that the laminate piece cannot be clamped in a first laminate direction but rather can be slide on the pallet in this direction. Two non-flat rigid contours which are identical or largely identical act on two opposing parallel laminate edge sections uniaxially and perpendicularly to the laminate plane and only in the first laminate direction, i.e. monodirectionally, and shape the entire heated laminate element into a monodirectionally molded blank.

In one aspect, an article includes a first sleeve formed from a first heat-shrinkable polymer sheet, the first heat-shrinkable polymer sheet having opposed first and second edges, wherein the first sleeve is formed with a first seam proximate the first edge. A portion of the first heat-shrinkable polymer sheet extends between the first sleeve and the second edge. A tag is bonded to the portion of the first heat-shrinkable polymer sheet proximate the second edge at a first overlap zone of the tag and the portion of the first heat-shrinkable polymer sheet. In another aspect, an article includes a heat-shrinkable polymer sheet and a tag bonded to the sheet. The heat-shrinkable polymer sheet has a central area and a plurality of slits disposed through the sheet, at least one of the plurality of slits oriented to partially surround the central area.

The present application discloses a bottle manufacturing method and a bottle, which comprises steps of: manufacturing a protection layer; printing an artwork on a surface of the protection layer; manufacturing a transparent layer; laminating the protection layer and the transparent layer having the artwork printed; arranging the protection layer and the transparent layer on a bottle body to make the artwork locate between the protection layer and the transparent layer. By printing the artwork between the protection layer and the transparent layer, the present application provides the artwork a good protection to prevent the artwork from worn, and makes the product a relatively high decoration quality.

An automated wrapping system for wrapping a substrate with a material includes a support and a nest mounted to the support that is configured to position the material between an outer portion of the substrate and the nest. The automated wrapping system also includes a material folding assembly positioned adjacent to the nest configured for movement between a rest position and an actuated position, wherein the movement of the material folding system to the actuated position engages and folds the free end portion of the material over the edge of the substrate and onto a part of the inner portion of the substrate while retaining the material against the edge of the substrate. An actuator connected to the material folding assembly moves the material folding assembly between the rest position and the actuated position.
