An apparatus including an overlay with a top side and a bottom side. The apparatus also can include an adhesive component with a top side and a bottom side. The top side of the adhesive component can be adhered to the bottom side of the overlay. The adhesive component can be configured to adhere the bottom side of the overlay to a screen of an electronic device in a single-use application of the overlay by adhering the bottom side of the adhesive component to the screen of the electronic device. The apparatus can be configured such that, when the overlay is removed from being adhered to the screen of the electronic device after the single-use application of the overlay, at least a portion of the adhesive component is detached from at least a portion of the overlay. Other embodiments are provided.

A portable film application apparatus includes a base, a positioning seat, a film holder, a conveyor and a film detaching device, wherein a positioning station and a film sticking station are provided on two sides of the base, respectively. The positioning seat is disposed at an end of the positioning station to lock the position of an electronic device. The film holder is disposed at an end of the film sticking station to lock the position of a film. The conveyor slides the positioning seat alternately between the positioning station and the film sticking station to match the electronic device with a membrane. The film detaching device is disposed at an end of the film sticking station to separate a release layer from the membrane.

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.

The present invention discloses a packaging box of a covering film and a film applicator. By structural designs of the packaging box and the covering film, the packaging box is provided with an internal cavity matching an outer shape of an electronic device and the covering film includes a release film having an extension portion, enabling the packaging box to provide the covering film with storage, dustproof and shock-absorbing functions and to further serve as a film application auxiliary tool when a film application process is performed. Thus, a user is allowed to accurately, quickly and efficiently form a layer providing protection on a surface of the electronic device directly by using the packaging box.

A service reinforcement sleeve is disclosed with a flange and a tubular section that can be used, with epoxy, to bind a service to a structural liner such as a cured-in-pipe structural liner. This sleeve has flexible tabs with lips (defined by cutouts) on the end of the tubular section opposite the flange. This sleeve can accommodate encrustation in the service, particularly when it is located away from the bottom of the service. A method of bonding a service and structural liner using this sleeve and epoxy is also disclosed that uses a metal brush or similar device to create a seat in the liner and abrade the lower portion of the service before insertion of the sleeve.

A device for installing a screen protector to an electronic device that includes a screen protector unit having a release film, a screen protector, and a protection film wherein the release film has a release tab, the protection film has at least one protection tab where the protection tab includes a hole formed therein; a tray having a panel, at least one alignment protrusion that fits the hole, a guide hole to allow external pressure to be applied onto the screen protector unit when the screen protector unit and the electronic device are received in the tray; and an adhesive strip, via the guide hole, further secures the screen protector unit to the tray. Also included is a method to using the device to install the screen protector to the screen of the electronic device.

According to one aspect of the present invention, an adhesive sheet material application device is disclosed, which includes a roller support bar, a roller support member, a first and second handle, and a roller. According to another aspect of the present invention, an adhesive sheet material application device is disclosed which includes a roller support member, a roller, and a second handle.

According to the utility model, there is provided a film laminator for cell phones, useful for film lamination on a surface of a cell phone, including: a cell phone fixing plate, on which a through hole for receiving the cell phone is established, and a top surface of which is a horizontal face; with at least one position limiting plate for abutting the cell phone within the through hole being also fixed on the top surface. The film laminator for cell phones further includes: a film laminating plate for fixing a cell phone film; one end of which is hinged to the cell phone fixing plate, and the other end of which is movable freely so that the film laminating plate is bonded with the top surface of the cell phone fixing plate. With respect to the film laminator for cell phones according to the utility model, because the position limiting plate is provided on the cell phone fixing plate, the surface of the cell phone to which a film is to be attached can handily be kept in flush with the top surface of the cell phone fixing plate. Upon film lamination, the film laminating plate can contact with the top surface of the cell phone fixing plate and the surface of the cell phone to which a film is to be attached at the same time, so that the stress that is laid on it in the course of film lamination is very even, and a good effect of film lamination is obtained.

A filament winding device includes a supporter configured to support a liner in a rotatable manner; a yarn supplying unit configured to support bobbins; a helical winding head configured to helical-wind a fiber bundles onto the liner; and a standard thread guiding mechanism configured to form a standard thread guide channel that guides a standard thread from the bobbins to the liner, the standard thread being different from the fiber bundles and being connected to leading ends of the fiber bundles, the standard thread guiding mechanism including nozzles configured to blow the standard thread with a compressed gas, and guide tubes configured to guide the standard thread blown by the nozzles, and the nozzles and the guide tubes being disposed along a fiber bundle guide channel, and capable of taking up the standard thread from the standard thread guide channel to the fiber bundle guide channel.
