The present application discloses a method and device for stacking cell pole pieces. The first mechanical hand simultaneously grabs corrected mn first pole pieces from the first position correction platform, and simultaneously places the mn first pole pieces on a separator of the same lamination table in m rows and n columns for lamination, and the second mechanical hand simultaneously grabs corrected mxn second pole pieces from the second position correction platform and simultaneously places mn second pole pieces on a separator on the same lamination table in m rows and n columns for lamination. By simultaneously laminating mn pole pieces on the same lamination table in an arrangement of m rows and n columns, multiple pole pieces can be stacked at one time, so as to improve the lamination efficiency.

The present application discloses a cell slitting method and a slitting device. The cell slitting method includes: controlling a pressing plate to tightly press a lamination unit on a cell support table, and controlling the slitting device to slit multiple layers of membranes of the lamination unit according to a pre-set slitting line to obtain mn independent cell bodies. With respect to the existing slitting device using the mode of cutting off a single cell single-layer tail membrane, according to the present application, the slitting device slits the lamination unit according to a pre-set slitting line such that mn independent cell bodies can be obtained by simultaneously cutting off multiple layers of membranes, which greatly improves the slitting efficiency and improves the production efficiency of cells.

In a method for producing garments or bandages two superimposed fabric layers are interconnected by a dot-, line-, or areal elastomer connection wherein on one of the fabric layers a three dimensional upstanding shaped part is formed by a layered application of an elastomer and is connected only to the fabric layer carrying the shaped part.

Disclosed is a new multi-layer nonwoven interlining and the production process thereof. The process allows a multi-layer nonwoven interlining to be obtained simultaneously with a single process on a single production line. The process includes a fiber opening step, a fiber feeding step, a carding step, a levelling step of the additional layer by the thermal treatment, and a point bonding step of the carded web and additional layer. As a result of the process, a structure is obtained where the carded web is point-bonded onto the additional layer.

A method for manufacturing a display device includes providing a preliminary display device including a display module, an optical layer disposed on a first surface of the display module, a first protective film disposed on the optical layer, a second protective film disposed on a second surface of the display module, a first adhesive layer disposed between the optical layer and the first protective film, and a second adhesive layer disposed between the second protective film and the display module, forming a mask layer on the first protective film by irradiating a first laser light on the first protective film along a first processing line, and cutting the preliminary display device at an outer periphery of the second processing line by irradiating a second laser light on the first protective film along a second processing line positioned at an outer periphery of the first processing line.

A window manufacturing method includes providing a first adhesive on a dummy substrate, providing a first mother substrate on the first adhesive, disposing a first portion of an interleaving paper on a surface of a suction stage disposed on the first mother substrate, the surface of the suction stage facing the first mother substrate, and pressing the suction stage toward the first mother substrate to attach the first mother substrate to the dummy substrate.

A laminating device includes: a plurality of laminating heads that each holds a unit laminated body; a drum section in which the plurality of laminating heads are arranged, which holds each laminating head swingably via a support shaft, and which rotates to advance each laminating head to a laminating position facing a lamination stage; a cam section which is in contact with each laminating head and which causes each laminating head to swing around the support shaft in association with a movement of each laminating head caused by a rotation of the drum section; and a biasing member that biases each laminating head in a radial direction of the drum section.

A cutting and attaching system for a screen protector having a high hardness is provided, and includes a cutting apparatus, a universal sheet having a hardness of at least 5H, and a film applicator. The cutting apparatus can perform a cutting process to the universal sheet through a cutter thereof according to the film applicator and a mobile apparatus, thereby forming a screen protector that is suitable to be applied to the film applicator and the mobile apparatus.

The present disclosure provides embodiments of a method a reinforced porcelain panel product for renovations or new constructions. In an embodiment, a method includes applying an adhesive to a top surface of a structural core board that includes a foam-core material. Further, the method continues with abuttingly contacting the structural core board to a bottom surface of a porcelain slab with the adhesive such that regions of the structural core board substantially extend beyond outer peripheries of the porcelain slab to define buffer regions, thereby to allow the buffer regions to be visible and to enhance protection from cracking when the reinforced porcelain panel product is handled. Additional features include the bottom surface of the structural core board having a second surface area larger than the first surface area of the porcelain slab and a fracture toughness greater than the porcelain slab.
