An apparatus for fabricating a laminated core includes a lower mold including a die including a die hole, an upper mold including a punch, a stripper plate operable to restrict upward and downward movements of a metal sheet at a lowest descending position during punching out of the metal sheet by the punch, an adhesive applicator included in the lower mold and operable to apply an adhesive onto a lower surface of the metal sheet, and a controller configured or programmed to control the stripper plate and the adhesive applicator. The controller is configured or programmed to include a movement controller to control upward and downward movements of the stripper plate, and an applicator controller to cause the adhesive applicator to apply the adhesive onto the lower surface of the metal sheet while the stripper plate is not located at the lowest descending position.

A method for the production of a laminated core is provided. A plurality of laminations are provided that are made of a soft-magnetic CoFe alloy and that have a first main surface and a second main surface that is located opposite the first main surface. An adhesive is applied to the first main surface of a first of the laminations by means of a printing process. The adhesive is then transferred to a partially cured B-stage. A second main surface of a second of the laminations is stacked on the B-stage adhesive, which is located on the first main surface of the first lamination, thereby forming a stack of loose laminations. The stack or the adhesive in the stack is cured, the adhesive thus being transferred to the fully cured C-stage in order to bond the first and second laminations to one another and so produce the laminated core.

A preparation method for artificial leather, includes applying a weaving process. The weaving includes adopting at least two groups of warp or weft yarns, and weaving each group of yarns into a monolayer structure to form at least two monolayer structures. Each of the monolayer structures is woven with some of the warp and/or weft yarns in such layer or with some of the warp and/or weft yarns in another layer to form a number of connecting points, such that at least two monolayer structures arranged in an orderly manner as two laminates are connected with each other by the weaving process, thereby forming a multi-layer integrated base fabric. The method includes bonding the base fabric and a resin layer together to form an artificial leather; and punching holes multiple air vent holes in the leather distributed in the resin layer and base fabric in the thickness direction.

A method for manufacturing a multilayer ceramic electronic device includes punching out a ceramic sheet by one of left and right side surfaces of a laminated body so as to form a side margin part on the one of the left and right side surfaces of said laminated body; and punching out another ceramic sheet by another of the left and right side surfaces of the laminated body so as to form a side margin part on the another of the left and right side surfaces of said laminated body, thereby forming a ceramic main body having the laminated body and the pair of side margin parts that respectively cover the left and right side surfaces of the laminated body. The width W is greater than the length L in the multilayer ceramic electronic device.

The invention relates to a vehicle seat protection cover, which has been manufactured from a one-piece material sheet, which consists, e.g., of a fleece. The vehicle seat protection cover according to the invention has a front layer and a back layer, which limit an upper pocket and a lower pocket. The vehicle seat protection cover comprises an opening extending over its entire length. For one embodiment the vehicle seat protection cover is made of a non-woven material or a fleece material.

Embodiments of the present invention relate to a system and method for manufacturing a three-dimensional object from a stack of pre-stripped layers of substrate. Each object layer is formed by (i) providing substrate comprising waste portion(s) and substrate-retained portion(s) that are attached to each other and separated from one another by cut(s) within the substrate; (ii) subsequently, subjecting the subject of each layer to a stripping process which selectively strips away substrate-waste portion(s) from the substrate-retained portion(s). After stripping, the object layer is added to a stack of previously-stacked object layers to grow the stack. This process is repeated to further grow the stack. Object layers of the stack are bonded to each other to build the three-dimensional object therefrom. Apparatus and methods for stripping are also describedany teaching or combination of teaching(s) related to stripping substrate may be employed in any additive-manufacturing process described herein.

A race for a mechanical clutch assembly may be formed from multiple race layers that assembled from pluralities of stamped arcuate segments. First and second race layers may have the same shape when their arcuate segments are assembled are assembled. The arcuate segments of the first race layer may be identical to each other, and the arcuate segments of the second race layer may be identical to each other, but the first layer arcuate segments are not identical to the second layer arcuate segments. Interlocking joints between the first layer arcuate segments are not aligned with interlocking joints between the second layer arcuate segments when the race layers are joined together and aligned for use in the mechanical clutch assembly.

A method for manufacturing a sound-absorbing panel with a sandwich structure for reducing noise impact of an aeronautic engine includes providing a first skin of a thermoplastic polymeric material, making a plurality of micro-holes through the first skin by mechanical punching of the first skin, securing the first skin to a central layer by arranging a structural adhesive layer between the first skin and the central layer and/or by a thermal weld between the first skin and the central layer, and securing the central layer to a second skin by arranging a structural adhesive layer between the central layer and the second skin and/or by a thermal weld between the central layer and the second skin.

The present invention is related to a flexible laminate for forming a reclosable packaging container comprising a built-in opening and reclose feature, said laminate comprising an inner structure and an outer structure, adhesively joined face-to-face, the outer structure forming the outer surface of the container and the inner structure forming the inner surface of the container, the outer structure comprising an outer flap portion delimited by a scoring line through the outer structure, and an inner structure comprising an inner flap portion delimited by a scoring line through the inner structure, the inner score line and the outer score line creating an opening into the container when the flap portions are peeled back, a marginal region of the outer flap portion extending beyond an edge of the inner flap portion and overlying an underlying surface of the inner structure, the inner and outer flap portions being joined in a second adhesive region and the first adhesive region being disposed between the marginal region of the outer flap portion and the underlying surface of the inner structure for attaching and re-attaching, in use, the outer flap portion to the underlying surface, wherein the bond/peel strength, measured according to ASTM F904-1998 (reapproved 2008), of the first adhesive region is smaller than the bond/peel strength of the second adhesive, the first adhesive being permanently tacky and covering the entire surface of either the inner structure or the outer structure, said first adhesive being patterned covered by an adhesion promoter, transforming said first adhesive into a second adhesive and creating patterns of first adhesive region and second adhesive region.
