According to one aspect of the present invention, an adhesive sheet material application device is disclosed, which includes a roller support bar, a handle, and a roller, where the handle and the roller are connected to the roller support bar, a portion of the handle is parallel to the roller, and the roller is rotatable. In another aspect of the present invention, a second handle is connected to the roller support bar and the second handle has a strap. According to another aspect of the present invention, a method of using the adhesive sheet material application device is disclosed, which includes securing a portion of adhesive sheet material to a surface, applying the adhesive sheet material to the surface with the adhesive sheet material application device, and regressing and eradicating bubbles between the adhesive sheet material and surface.

The present Invention discloses two robot assisted automated methods for application of decals on complex 3 dimensional surfaces without wrinkle and bubble. The method includes loading of objects having 3D surfaces on an object holding fixture manually from a conveyor belt, picking up a first application fixture automatically by a robot, peeling off the liner disposed on the decal manually and placing the decal on the first application fixture which holds the decal by suction, positioning the decal with exposed adhesive accurately on a first 3D surface of the object and switching off the suction automatically leaving the decal placed on the 3D surface of the object, placing the first application fixture back and picking up a second application fixture automatically by the robot for squeegee application, applying the second application fixture to complete the squeegee application by pressurizing the decal. The first application fixture is configured to be programmed to hold decals of different shape and size and the second application fixture is configured to be programmed to identify the 3D direction of squeezing pad motion within each region of such decals to eliminate the bubbles without wrinkling. The second method uses a mechatronic pick and place mechanism for picking up a decal from the decal stack and placing of the decal on the 3D surface of the object automatically.

In combination with a mobile communications device equipped with a display, and a film equipped with an adhesive backing and a release liner, a tool is provided for applying the film to the display. The tool includes a substrate having a depression therein in which the mobile communications device is seated; first and second opposing rails disposed on opposing sides of the depression; and a film applicator which travels along the first and second rails. The film applicator is equipped with first and second wheels which engage the first and second rails, respectively, and is further equipped with a blade which pressingly engages the film as the film applicator which travels along the first and second rails.

A two-stage application device is disclosed for installing a screen protector on a display screen of a screen-mounted device. The application device includes a base, a first actuating lever, and a second actuating lever. The base includes an accommodation and a support, wherein the support defines first grooves and second grooves. The first actuating lever has first controlled pivot portions guided and limited by the first grooves, a first pressing portion, a first arm, and a body with a positioning protrusion. 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.

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 flange may be configured to couple to the protective film. The flange may aid in the accurate application of the protective film to the electronic device.

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 apparatus may be used to apply the protective film on the surface of the electronic device. The roller apparatus may include an opening for receiving a display peg.

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.

The present disclosure provides a cloth attaching device and a cloth attaching method. The cloth attaching device comprises: a cylindrical base, a rubbing roller opposing the cylindrical base and an actuating unit, an annular adhesive layer covering a cylindrical surface of the cylindrical base; a first connecting component holding both ends of the cylindrical base and connecting to the actuating unit; and a second connecting component holding both ends of the robbing roller and connecting to the actuating unit. The actuating unit is configured to control a movement of the first connecting component and the second connecting component so that the rubbing roller and the cylindrical base rotate in sync or not in sync. The present disclosure overcomes defects in which the rubber pad displaces very easily and the aging process is very time consuming, which facilitates to improve fabricating efficiency and quality of the rubbing roller.

A system for protecting a surface of a substrate includes a protective film, which is configured to be applied and secured to the surface, as well as a backing on an adherent surface of the protective film and an application tape over an exterior surface of the protective film. Protruding features, such as tabs, adjacent to different peripheral edges of the protective film may enable removal of the backing and the application tape from the protective film, and may include features that indicate the order in which each protruding feature is to be grasped to peel its corresponding element away from the protective film. Methods of using such a system are also disclosed.
