A mobile phone screen protector device includes a positioning seat, a positioning frame, an auxiliary adhesive sheet, a screen protector, and a scraper. The positioning seat has a first raised portion, a second raised portion, and a positioning space between the first and second raised portions for accommodating a mobile phone with a screen facing upward. The first raised portion is higher than the second raised portion. The auxiliary adhesive sheet is adhered to an underside of the positioning frame. The screen protector is adhered to an underside of the auxiliary adhesive sheet. The positioning frame and the auxiliary adhesive sheet are confined to the tops of the first and second raised portions, and the screen protector is inclined at an angle relative to the screen. The scraper is pressed to scrape against the auxiliary adhesive sheet for the screen protector to be adhered to the screen.

A screen protector installation machine uses a screen protector laminate to apply a screen protector to a cell phone. The laminate comprise a web that carries the screen protector and a backing layer. The laminate is carried by a lid coupled to a base and closable over the base. An impression in the base receives the cell phone. A first slider is carried by the lid and comprises a spool rotatable with respect to the lid. A tab of the backing layer is coupled to the spool. As the slider slides over the cell phone, the spool rotates to wind the backing layer around the spool to expose the screen protector. The lid properly positions and orients the screen protector over the mobile device. The lid is automatically lowered onto the base, and the screen protector is automatically lowered onto the mobile device, by movement of the first slider after the backing layer is removed.

Systems and methods for applying a protective layer to an outer surface of a mobile device. A system may include a protective layer for an outer surface of a mobile device and an alignment layer coupled to the protective layer. A frame may define a cavity configured to receive the mobile device. The frame may include a surface positioned outside of the cavity and configured to support the alignment layer and configured to be depressed relative to the mobile device to reduce a distance between the protective layer and the outer surface of the mobile device when the mobile device is positioned in the cavity.

A machine for applying tubular film to products includes a film feed path along which a supply of continuous tubular film is fed, and a sleeve eject station at which the film tubing is cut into sleeves that are ejected onto products passing the sleeve eject station. At least one sensor is positioned along the film feed path upstream of the sleeve eject station for detecting a splice in tubular film traveling along the film feed path. A controller is configured for controlling the machine such that, upon detection of a splice in the tubular film, a defective sleeve that includes the splice thereon is ejected into a gap between successive products so as to prevent application of the defective sleeve to any product.

A bladder mandrel package, used to manufacture a composite structure, includes a mandrel and a wrap ply, surrounding the mandrel to form a wrapped mandrel. The bladder mandrel package also includes a first radius filler, coupled to the wrap ply at a first radius of the wrapped mandrel, and a second radius filler coupled to the wrap ply at a second radius of the wrapped mandrel. The mandrel, the wrap ply, the first radius filler, and the second radius filler are consolidated to from the bladder mandrel package.

A fixture for bonding films to an object includes a base, a cavity wall fixed to the base, and a receiving cavity defined by the cavity wall and the base. The cavity wall includes opposing inner and outer surfaces and an end surface at an end away from the base. The end surface defines protrusions interconnecting with recesses and being recessed towards the base. Each recess penetrates the inner surface and the outer surface. A method for employing the device is also provided. The fixture and the method for bonding avoid center wrapping after bonding.

A screen protector laminate applicator is used with an installation machine to install a screen protector on a mobile device. The laminate applicator comprises a web secured to the installation machine; the screen protector carried by the web, and a backing layer covering the screen protector opposite the web. The web, the screen protector and the backing layer are removably coupled together as a laminate. A tab of the backing layer extends beyond the perimeter of the screen protector and comprises an enlarged head connected to the backing layer by a narrower neck.

An applicator is provided for applying protective films to electronic device displays. The applicator includes a base, a screen protector, and a squeegee. The base includes a pocket for receiving an electronic device. The screen protector is affixed to the base so as to overlie an electronic device. The screen protector preferably includes three layers including a protective film, cap sheet, and back liner. The squeegee is provided for removing the back liner and for simultaneously affixing the protective film to an electronic device.
