In a method for manufacturing lamination stacks of controlled height in a tool, starting material is provided as continuous strip delivered from a coil or as an individual sheet. Laminations are punched from the starting material in several punching steps to a required contour of the laminations. A heat-curing adhesive is applied onto the laminations prior to performing a last punching step. The laminations are combined to a lamination stack. The laminations of the lamination stack are partially or completely heated in a lamination storage. The adhesive is liquefied by heating the lamination stack to build up adhesion and then solidified. Curing the adhesive at the liquefying temperature or solidifying the adhesive in the tool by cooling and subsequently heating the adhesive to a temperature below the liquefying temperature is possible so that the adhesive does not melt but undergoes further curing resulting in higher temperature stability.

A sandwich component comprising: (i) a first main surface with a first cover layer and a second main surface with a second cover layer, the first cover layer and/or second cover layer having an opening, weakening, or marking in a lateral region and/or is provided with the same, (ii) at least one intermediate layer positioned between the first and second cover layers, and (iii) a polymer composition which is arranged between the first and the second cover layers substantially within the intermediate layer and/or in the region of the opening, weakening, or marking. A mechanical connection mechanism is fixed, or can be fixed, directly in the polymer composition through the first cover layer and/or the second cover layer and/or in the lateral region in the region of the opening, weakening, or marking so as to pass through the first cover layer and/or the second cover layer and/or the lateral region.

This disclosure includes sandwich composites comprising fiber-reinforced laminates. The disclosure further includes one or more film adhesives between a core and the fiber-reinforced laminates.

An object of the present invention is to provide a thin volume hologram sheet to be embedded sufficiently resistant to a mechanical stress such as a stress including a tensile stress, a shear stress and a compression stress at the time of processing even under a heating condition, a forgery prevention paper and a card using the same. The object is achieved by providing a volume hologram sheet to be embedded comprising a volume hologram layer, and a substrate disposed only on one side surface of the volume hologram layer using an adhesion means, wherein a peeling strength of the volume hologram layer and the substrate is 25 gf/25 mm or more.

An apparatus for applying a liquid adhesive according to an embodiment of the present invention includes: a side part including a support surface configured to support one surface of an upright secondary battery; and a lower part including an adhesion space configured to accommodate the liquid adhesive therein and configured to accommodate insertion of a sealing part disposed at the one surface of the upright secondary battery, the lower part having a passage extending from an outer periphery of the lower part to the adhesion space, the passage configured to permit the liquid adhesive to flow from the outer periphery to the adhesion space, wherein the lower part is disposed below the side part.

A method for manufacturing an image display device includes applying a first photo-curable resin composition to a protective panel to form a first photo-curable resin composition layer. The first photo-curable resin composition layer is irradiated with curing light to form a first cured resin layer. A second photo-curable resin composition is applied to the first cured resin layer to form a second photo-curable resin composition layer. The second photo-curable resin composition layer has a reduced or eliminated height difference, compared with the first photo-curable resin composition layer. The protective panel and an image display member are laminated via the second photo-curable resin composition layer. The second photo-curable resin composition layer is irradiated with curing light.

This invention relates to a process for the division of an individual input source log into discrete longitudinal lengths for subsequent processing. The process comprises receiving an individual input source log, dividing the input source log into one or a plurality of output log portions of a predetermined length, wherein at least a portion of said output log portions resultant from said division are of a substantially equal or substantially constant or consistent longitudinal length, and wherein said substantially equal or substantially constant or consistent longitudinal length output log portions are procured as a feed stream of log material for a subsequent processing step. This process provides for the processing of logs and subsequent assembly into an end product formed from a composite of sticks derived from said processed logs.

A method for manufacturing an optical article including the following steps: a. providing a first substrate with a main surface, b. depositing a second substrate on the main surface with an adhesive layer so that the space between the first substrate and second substrate is filled by the adhesive layer, c. curing the adhesive layer to induce a polymerization of the adhesive layer, wherein a tension step takes place after steps a. and b., and before step c., the tension step including applying symmetrically a tension, preferentially with a central symmetry, preferentially a radial isotropic tension or an ortho-distributed symmetrical tension, on the edges of the second substrate sensibly in a tension plan parallel to a plan representative of the main surface.

Described are techniques and equipment (apparatus) for processing an electrostatic chuck at controlled process conditions, including, as an example, for processing an electrostatic chuck during a step of curing an adhesive that forms a bond between two layers of the electrostatic chuck.
