A system and method for removing a backing from a ply of composite material is disclosed. The system includes a roller having a roller axis and a roller surface that circumscribes the roller axis. The system also includes an adhesion feature disposed on the roller surface. The system further includes a roller drive to move the roller along a travel path that is perpendicular to the roller axis and to rotate the roller about the roller axis.

A method of stripping films which are stuck together without damage is disclosed. The whole reel of films which are stuck together is placed in a sealing device with outlet valves. Liquid nitrogen is added at a bottom of the sealing device. The films are stripped off by a flow of gas through gaps between the layers of the films while the vaporization of liquid nitrogen. The present invention adopts a natural force of liquid nitrogen vaporization to strip the films, which does not compromise the PH value, the dimensional performance and the mechanical performance of the films. The films are in stripped off without damage. The conventional method of stripping the films causes the fragile film to break off or the image layer with a decreased combing power to detach. The present invention has the advantages of simple operation, low cost and good promotion value.

Methods for separating a plurality of diamagnetic directed self-assembled diamagnetic components are provided. One method includes, for instance: contacting a release substrate to the plurality of diamagnetic components, the plurality of diamagnetic components including a non-diamagnetic component affixed to a diamagnetic portion by a first adhesive, and removing the release substrate, the non-diamagnetic component being affixed to a final substrate by a second adhesive and the release substrate being affixed to the diamagnetic portion by a third adhesive, and wherein the removing removes the diamagnetic portion and at least a portion of the first adhesive from the non-diamagnetic component.

A technique for protecting a portion of a screen panel during a process for disassembling and servicing a display screen device is provided. A first part of the display screen device is separated from a screen panel part of the display screen device, where the screen panel part includes a main screen portion and a circuit of flexible printable circuit board (FPCB) portion. An encapsulant is applied onto a break protectable layer (BPL) of the circuit of flexible printable circuit board (FPCB) portion. The screen panel part is washed, with a solvent to remove residue from the main screen portion.

A separating device and method for a bonded cine film, belonging to the field of image file protection and repair technologies. The separating device comprises a pressurizing device, a separating device and a liquid nitrogen storage device. The pressurizing device is connected to the liquid nitrogen storage device; the liquid nitrogen storage device is connected to the separating device for providing liquid nitrogen thereto; the separating device comprises a film receiving chamber for accommodating a film to be separated; the pressurizing device pressurizes the liquid nitrogen storage device allowing liquid nitrogen to enter the film receiving chamber. Due to a difference between expansion coefficients of a base layer and emulsion layer of the film under low temperature, micro-pores and gaps may be generated in the base layer and the emulsion layer of a bonded film roll; the liquid nitrogen penetrates into the micro-pores and gaps of the bonded film.

A method for manufacturing a textile product includes the steps of providing an intermediate product formed by a backing having a front surface and a back surface, and yarns applied into the backing, the yarns extending from the front surface of the backing material, feeding the intermediate product along a body having a heated surface, the back surface being pressed against the heated surface, to at least partly melt the yarns present in the intermediate product to form the textile product, wherein the part of the back surface that is pressed against the heated surface has a relative speed with respect to the heated surface, and a device enabling applications of this method and to a floor covering incorporating such a textile product connected to a dimensionally stable carrier sheet using thermo reversible covalent interactions.

A method and apparatus for replacement of damages display shield (typically glass) covering a display screen on a device, typically a mobile phone. Mobile phones have an electronic display protected by a glass shield. Between the glass and the display is often a plastic polarizing or other intermediary sheet. Removal of a damage glass can be accomplished by cutting thru the polarizer with a moving wire or blade. This separates the glass from the sensitive display and allows replacement of the glass without damaging the more expensive display.

A method for separating and recovering a layered film laminated and adhered with a reactive adhesive, the method including a step 1 of immersing the layered film in an alkaline solution while stirring the layered film with heating at 20? C. to 90? C. or ultrasonically vibrating the layered film and a step 2 of recovering separated single-layered films that constitute the respective layers of the layered film. The reactive adhesive is preferably a reactive adhesive containing a polyisocyanate composition and a polyol composition and more preferably a reactive adhesive containing a polyisocyanate composition, a polyol composition, and a compound having an acidic group.

The invention relates to the use of mixtures of water and essential oils selected from the group consisting of phenols, phenylpropanoids and furanocoumarins, for separating multilayered composites for the segregated recycling of polymer/metal films.
