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.

A protective film peeling apparatus includes a peeling tape, a tape support portion disposed under one side of the peeling tape, a first pressing portion which is disposed on the one side of the peeling and fixes the one side of the peeling tape to the tape support portion, a second pressing portion which is disposed on another side of the peeling tape and presses and attaches the another side of the peeling tape to one side of a dummy portion of a protective film on a panel, and a grip portion disposed on the dummy portion. The tape support portion and the first pressing portion peel the one side of the dummy portion and a predetermined portion of the dummy portion, and the grip portion peel a remaining portion of the dummy portion.

A method of peeling off the protective film includes: providing a panel lower sheet, where a protective film is provided on one surface of the plane lower sheet and the protective film has a bending line extending in a first direction parallel to opposing sides thereof; gripping a portion of the protective film; moving the gripped portion of the protective film in a second direction which is a thickness direction thereof; and moving the panel lower sheet in a third direction perpendicular to the bending line.

According to one embodiment, a label peeling device includes a tray, a pressing unit, and a control unit. The tray is configured to support a label sheet thereon. The pressing unit is configured to be driven in a direction perpendicular to a conveyance direction of the label sheet. The control unit is configured to drive the pressing unit toward a central portion of the label sheet supported on the tray. The control unit performs peeling control to peel a liner sheet and a label body of the label sheet from each other by pressing an edge of the label sheet and thereby curving the label sheet.

Disclosed is a turntable cloth peeling jig including: a cylindrical winding cylinder including a slit formed on an outer periphery of the cylindrical winding cylinder and extending in an axial direction thereof; a cloth clamping member disposed inside the winding cylinder and configured to clamp an outer peripheral edge of a cloth inserted into the slit; an extension bar attached to one end portion of the winding cylinder so as to extend coaxially therewith; an engaging portion provided at a tip end portion of the extension bar and engaged with a rotation jig configured to rotate the winding cylinder; and a handle provided in the engaging portion and configured to support the winding cylinder when rotating the rotating jig.

A blade includes an edge to be pressed against an end portion of a carrier film to fold the end portion upwards from a sheet. A clamp mechanism peels the carrier film off from the sheet by moving while clamping the upwardly folded end portion of the carrier film.

A label assembly including a face sheet, a back sheet, and a layer of an adhesive positioned between the face sheet and the back sheet. A separation line divides the label assembly into at least two portions. The separation line is formed by a first tearable line of separation extending across the back sheet and a second tearable line of separation extending across the face sheet. The first tearable line of separation is offset with respect to the second tearable line of separation, and at least one of the first and second tearable lines of separation includes a non-linear portion directed toward and/or an angled portion extending at an angle to an other of the at least one of the first and second tearable lines of separation.

A substrate separation system configured to remove a substrate from a carrier is provided. The substrate separation system includes a stage, an upper fixing portion, a suction portion, a cutting portion and a blowing portion. The stage is configured to carry the carrier. The upper fixing portion is disposed above the stage so as to be movable up and down. The suction portion is disposed above the stage so as to be movable up and down, and has a hollow portion to accommodate the upper fixing portion. The cutting portion is disposed on one side of the stage. The blowing portion is disposed on another side of the stage, and is configured to provide a blowing force to a position between the substrate and the carrier.

A label web and method utilize a substrate, first and second longitudinally spaced label arrays each including two or more double-sided adhesive labels removably attached to the substrate, and a peelable protective covering web extending generally coextensive with the substrate. The label arrays and the peelable protective web are configured such that the peelable protective web is selectively removable to expose the first label array while remaining removably attached to the second label array, with both the first and second label arrays remaining removably attached to the substrate, to thereby facilitate removal of all labels in the first label array as a group while the peelable protective covering web remains in place over the second label array.
