A method of manufacturing sheeting is provided, the method including the steps of forming multiple recesses in a symmetrical repeat pattern on a sheet of material, extruding a molten material to form an upper outside wall and a lower outside wall, interposing the formed sheet between the upper outside wall and the lower outside wall, and fixing the interposed sheet to the upper outside wall and the lower outside wall. Also provided is sheeting having an upper outside wall and a lower outside wall and an interposed sheet fixed between the outside walls. The interposed sheet includes multiple recesses in a symmetrical repeat pattern, where the upper and lower outside walls are, or the interposed sheet is, manufactured from a material which includes a polymeric material.

A sound damping wallboard and methods of forming a sound damping wallboard are disclosed. The sound damping wallboard comprises a gypsum layer with a gypsum surface having an encasing layer. The encasing layer is partially removed to expose the gypsum surface and form a gypsum surface portion and a first encasing layer portion on the gypsum layer. A sound damping layer is applied to the gypsum layer to cover at least part of the gypsum surface portion and the encasing layer portion.

The present disclosure is directed to a new technique that can sufficiently suppress bonding defects by identifying application defect sites with a high accuracy when manufacturing a secondary battery laminate including battery members which are bonded together via an adhesive material. An inspection method of the present disclosure is an inspection method used upon forming a dry material on at least one bonding surface of an electrode and a separator, through the steps of applying a coating material on the bonding surface and forming the adhesive material by drying the coating material. In this inspection method, prior to the step of forming the adhesive material, the displacement of the bonding surface to which the coating material has been applied is measured by a laser displacement gauge to identify an application defect site.

A process for preparing a printed rigid plastic substrate is described, the process comprising: providing a rigid plastic substrate comprising a primer on a surface of the rigid plastic substrate, the primer comprising a primer resin; printing a liquid electrophotographic ink composition comprising a thermoplastic resin onto the primer on the surface of the rigid plastic substrate; depositing a cross-linking composition comprising a cross-linker onto the printed electrophotographic ink composition disposed on the primer; and laminating the rigid plastic substrate with a flexible film such that the ink composition and the cross-linker are disposed between the rigid substrate and the flexible film and wherein the lamination of the rigid substrate with the flexible film causes cross-linking of the thermoplastic resin of the ink composition and of the primer resin.

A method for the production of an elastic laminate, with the following steps in a production line: coextrudeing a first web of elastic film with at least three layers, with at least two different polymer materials, to feed contemporaneously said coextruded first elastic film web and two second nonwoven webs to a thermal, binding calender, wherein the first elastic film web is arranged between said two second nonwoven webs when entering the calender; wherein said first elastic film web, during the movement from the coextrusion step to the thermal binding step, passes from a melted state, to a solidified and cold state when entering the calender, to join, through spot welding in said calender, said second nonwoven webs with respective opposite outer layers of said first elastic film web, thus producing an intermediate web, to stretch mechanically said intermediate web according to a direction transverse to the same web.

A stretchable electronic device is provided. The stretchable electronic device includes a stretchable elastomer polymer base substrate; a plurality of electronic devices; and a plurality of recesses partially extending into the stretchable elastomer polymer base substrate. The stretchable elastomer polymer base substrate includes a plurality of stiffened portions respectively in a plurality of stiffened regions spaced apart by one or more elastomeric portions in one or more elastomeric regions. A respective electronic device of the plurality of electronic devices is at least partially in a respective recess of the plurality of recesses, and is in a respective stiffened region of the plurality of stiffened regions. The respective electronic device in the respective recess is stacked on a respective stiffened portion of the plurality of stiffened portions.

A touch sensor comprises a touch sensor layer having an electrode pad portion formed in a bezel area, and a polarizing layer coupled to the touch sensor layer while opening an area of the electrode pad portion and having a side surface of an area of the electrode pad portion defining an altered surface and a side surface excluding the area of the electrode pad portion defining a straight line surface. The altered surface and the straight line surface have a cross-sectional inclination angle of 30° or less in a lateral direction with respect to a vertical direction.
