METHOD FOR BONDING AT LEAST PARTIALLY OVERLAPPING MATERIAL LAYERS AND AUTOMATIC BONDING APPARATUS FOR PERFORMING THE METHOD
An automatic bonding apparatus and a method for thermally induced seam bonding of weldable and/or gluable flat flexible material layers with each other which are each configured as a material web, material band and/or material piece and arranged so that they overlap at least partially wherein the bonding is performed by an electrically controlled contact heating arrangement through a heating wedge welding method. A temperature and/or a power of the heating wedge which is formed by a thin folded steel sheet blank is controlled as a function of a relative velocity between the material layers and the automatic bonding apparatus. This is performed so that a thermal energy that is transferred from the heating wedge to the material layers to be glued is kept constant. For this purpose the relative velocity is detected and the power of the heating wedge is automatically adjusted when the relative velocity changes.
POLYURETHANE LOGO LABEL MANUFACTURING METHOD AND POLYURETHANE LOGO LABEL ATTACHMENT METHOD
The present disclosure relates to a polyurethane logo label manufacturing method that includes: a first step of preparing a polyurethane image film printed with a logo; a second step of preparing a wing film laminated by combining a polyurethane film and a PET film; a third step of forming an injection hole for injection into a log groove of the wing film; a fourth step of film molding option of preparing a mold composed of a top plate, a mid-plate, and a bottom plate; and a fifth step of injection molding of injecting polyurethane resin into the logo groove through the injection inlet of the top plate of the fourth step.
Cutting method of flexible display panel, controlling device in the cutting method, and cutting apparatus of flexible display panel
Disclosed are a cutting method of flexible display panel, a controlling device in the cutting method and a cutting apparatus of flexible display panel. The cutting method comprises steps of placing a transparent substrate (21) carried with a flexible film layer (22) on a base (10); cutting only the transparent substrate (21) by means of a cutting tool (30); obtaining a cutting trace of the cutting tool (30); and controlling a laser knife (40) to cut the flexible film layer (22) carried on the transparent substrate (21) along the cutting trace of the cutting tool cutting the transparent substrate. In this way, by controlling the laser knife (40) to cut the flexible film layer (22) disposed on the transparent substrate (21) following the cutting trace of the cutting tool (30) cutting the transparent substrate (21), the flexible film layer (22) can be completely cut at the same time when or after the transparent substrate (21) is completely cut, so as to avoid rough selvedges during cutting the flexible film layer (22), thereby improving the cutting effect of cutting the flexible display panel; besides, in case that the cutting tool (30) and the laser knife (40) operate in parallel cutting mode, it can also improve the cutting efficiency.
Aircraft Display Panel Bonding System
A method and apparatus for conforming a display panel to a surface of an aircraft structure. The method positions the display panel within a resin barrier that is located on the surface such that a cavity is formed, places a film and the display panel together, and applies a force on the display panel that causes the display panel to conform to the surface of the aircraft structure. The display panel has a shape that changes to a first shape to match a second shape of the surface of the aircraft structure. The method also injects a resin into the cavity while the force is applied, and cures the resin in the cavity while the force is applied to form a cured resin. The cured resin holds the display panel in the first shape and attaches the display panel to the surface of the aircraft structure.
