The disclosure relates to a device (e.g., a jig) for attaching a protective film for protecting a display included in a foldable electronic device from impact and scratching. A film attaching apparatus for attaching a film to an electronic device is provided. The film attaching apparatus includes a display, wherein the film attaching apparatus may include a main body including a base plate, a jig disposed on a base plate and configured to seat the electronic device thereon, a film suction-fixing part inclined at a predetermined angle with respect to the jig, and a roller module disposed on the base plate and including a roller slidable above the jig, wherein the film suction-fixing part may include two or more divided suction areas which are sequentially arranged to correspond to a moving direction of the roller module and configured to have different suction forces.

An elastic sheet stretchable structure in which a first sheet layer and a second sheet layer are bonded through joint holes penetrating an elastic film at a plurality of sheet joined portions arranged at intervals is included. Joined portion groups in the stretchable region are in a relationship of intersecting a stretchable direction line at respective positions in an orthogonal direction or in a relationship of not intersecting the stretchable direction line at a separation width of 0.5 mm or less in the orthogonal direction of the stretchable direction line. The joined portion groups are in a relationship of not intersecting an oblique line at a predetermined separation width in the orthogonal direction in an oblique line group of oblique lines q in the orthogonal direction intersecting the stretchable direction line within an angle range γ of 45 degrees or less.

A roll conveying unit of a joined body manufacturing apparatus includes a rotating unit and a suction unit. The outer peripheral surface of the rotating unit includes a contact suction portion that makes contact with a first back surface. The rotating unit rotates while bringing the contact suction portion into contact with the first back surface. The suction unit suctions the second layer from the contact suction portion through pores of the first layer, to thereby form a suctioned portion attracted to the contact suction portion under suction, in a laminated body of the first layer and the second layer. The peeling unit peels the coating film from the second back surface of the suctioned portion of the film-attached joined body.

A foil transfer device is configured to dispose a sheet on a foil film containing a foil and transfer the foil onto the sheet. The foil transfer device includes a heating member configured to heat the foil film and the sheet, a pressure member configured to nip the foil film and the sheet with the heating member, a first temperature sensor, and a controller. The controller determines whether the first temperature sensor has failed based on a voltage value of the first temperature sensor.

A method for making a layered structure without any defects, including a first support layer, a second support layer, and an adhesive intermediate layer interposed between the first layer and the second layer which is adapted to fix the layers on each other. The intermediate layer embeds operatively at least a three-dimensional macroscopic element being made of crystal glass or precious stones, and the intermediate layer is made of a thermoplastic resin having a melting temperature.

A mini smart card and a method of manufacturing the mini smart card are introduced. The method includes disposing bilayered print layers on a top side and a bottom side of a circuit layer, respectively; performing a heat-compression treatment and then a printing treatment on the circuit layer and the bilayered print layers; removing surface layers from the bilayered print layers; and disposing transparent protective layers on the bilayered print layers, respectively. The bilayered print layers are prevented from deforming under the heat generated during the printing treatment. Removal of the surface layers from the bilayered print layers effectively reduces the thickness of the mini smart card.

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.

The present invention provides an apparatus for producing a laminated steel core, which is capable of punching out steel core sheets having a predetermined shape from a thin steel strip while stably supporting the thin steel strip. The present invention also provides a method for producing a laminated steel core. A support 23a provided in a lower die 21 supports a thin steel strip 22 from its bottom and extends across the width of the thin steel strip and in the feed direction of the thin steel strip.

Discussed is an electrode assembly manufacturing method including an operation of stacking an electrode and separator to form an electrode stack and an operation of laminating the electrode stack while heating the electrode stack in order to manufacture an electrode assembly having increased force of coupling between the electrode and the separator while preventing damage to the electrode assembly.

An overlay applicator tray including a cradle including a device slot. The device slot is configured to securely hold an electronic device in the cradle. The overlay applicator tray also can include an overlay applicator. The overlay applicator can include an overlay layer and an adhesive release liner. The overlay layer can include a top side and a bottom side. The bottom side is configured to be adhered to a screen of the electronic device. The adhesive release liner is removably attached to the bottom side of the overlay layer. The overlay applicator tray additionally can include an alignment piece coupling the cradle to the overlay applicator. The alignment piece aligns the overlay layer of the overlay applicator with the screen as the overlay layer is applied to the screen when the electronic device is securely held in the device slot. The overlay applicator tray further can include a first pull tab on the adhesive release liner. The first pull tab is configured to be pulled to remove the adhesive release liner from the bottom side of the overlay layer and expose an adhesive of the overlay layer. Other embodiments are described.
