The second actuating lever has second controlled pivot portions guided and limited by the second grooves, a second pressing portion, a second arm, and a body. A kit is also disclosed for protecting a display screen of a screen-mounted device, which includes a two-stage application device, and at least one screen protector including a protective film with at least one adhesive layer, and a backing sheet.

An overlay applicator can include an overlay with a top side and a bottom side. The bottom side can include an adhesive agent configured to adhere to a screen of an electronic device. The overlay applicator can include an adhesive release liner. The adhesive release liner can include a top side and a bottom side. The top side of the adhesive release liner can be removably attached to the bottom side of the overlay. The adhesive release liner can be configured to protect the adhesive agent at the bottom side of the overlay from contaminants. The overlay applicator can include a protective film removably attached to the top side of the overlay. The overlay applicator can include an alignment tab. The alignment tab can include an alignment mechanism. The overlay applicator further can include a pull tab. The pull can include a wiper. Other embodiments are provided.

Systems and films for protecting surfaces of various substrates, including electronic devices, such as portable electronic devices, include a liner with a strip liner and a main liner. The strip liner, which covers a small strip of adhesive on the back side of a protective film, is configured to be removed before the main liner. With the small strip of adhesive exposed, the protective film may be aligned with a substrate and, if necessary, removed from the substrates and repositioned thereon. Thereafter, the main liner may be removed to enable complete application of the protective film to the substrate. Methods for securing protective films to substrates are also disclosed.

A method for processing floorboards using digital printing, comprising: preparing a base material layer; arranging a printing layer on the base material layer, wherein the printing layer is directly printed by a digital printing apparatus and is formed on a surface of the base material layer; and arranging a protection layer on the printing layer, wherein the protection layer is attached to the printing layer by means of one or a combination of processes selected from roll-coating, shower-coating, spray-coating, transfer-printing and printing, wherein the protection layer displays one or a combination of artistic effects selected from flat, sunken, raised, finely creased, patterned and crackled by means of one or a combination of processes selected from levelling, flatting, printing, embossing, corroding, carving, brushing and crackling. According to the processing technology of the present disclosure, various patterns can be designed and processed in different ways or combinations according to the user's requirements.

An autonomous application machine installs screen protectors on mobile devices, such as cell phones. The machine has an enclosure with an interior. A cleaning station has a cleaning implement to contact a screen of the mobile device. A magazine carries a plurality of screen protectors. A lamination station has an applicator to place a screen protector from the magazine on the screen of the mobile device. A vision inspection station has a light source and a camera to initially visually inspect the screen of mobile device prior to cleaning in the cleaning station and to verify that the screen is undamaged and free of an existing screen protector; and subsequently visually inspect the screen protector on the mobile device after installation in the lamination station and to verify that the screen protector has been properly installed.

Devices, methods and systems disclosed herein relate to the application of a protective film on a surface of an electronic device that instantly reduces air bubbles and eliminates the waiting time usually required when using a wet fluid solution. In one embodiment, a roller device may include a carriage or housing and one or more rollers coupled or integrated with the housing, configured to apply a protective material to a surface of the electronic device in a first orientation, and configured to function as a device stand in a second orientation. In addition or alternatively, a roller guide apparatus and/or a wedge may be utilized to assist the roller device in applying the protective material to the surface of the electronic device.

An apparatus is provided for assisting in affixing a screen protector to a display of an electronic device. The apparatus includes a base including a platform configured to support the electronic device. The apparatus includes a lid configured to cover at least a portion of the base and the supported electronic device. The lid includes an aperture.

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 film-application apparatus includes a body including a first body half, a second body half, and a hinge coupling the body halves; and a squeegee blade movable from a first position relative to the body to a second position relative to the body. The second body half is rotatable about the hinge relative to the first body half to a closed position. When the second body half is in the closed position, the body includes a top ring and a bottom ring both centered on an axis and defining an axial gap therebetween. When the second body half is in the closed position and the body is enclosing a sensor having a cylindrical sensor window, the axial gap exposes the cylindrical sensor window, and moving the squeegee blade from the first position to the second position covers substantially an entire surface area of the cylindrical sensor window.
