A surface of the first masking film member facing the at least one conductive pattern may include a photosensitive adhesive layer containing a photo-initiator and having an adhesive force reduced or removed through irradiation of ultraviolet (UV) rays.

A multilayer foam film suitable for direct and non-direct food contact and aseptic packaging application is disclosed.

Described is a method of making a densified fiber batt that includes the steps of: a) providing a fiber batt with a first plurality of fibers having a first melting point and a second plurality of fibers having a second melting point different from the first melting point; and b) subjecting the fiber batt to heat and pressure in a static press, thereby forming a densified fiber batt having a first surface and an opposed second surface.

A method of forming deformations in a nonwoven web includes the steps of: a) providing a precursor nonwoven web; b) providing a pair of forming members which include: a first forming member having a surface comprising a plurality of discrete, spaced apart male forming elements; and a second forming member having a surface comprising a plurality of recesses in the second forming member, wherein the recesses are aligned and configured to receive the male forming elements therein, wherein the recesses have a plan view periphery that is larger than, and may completely surround, the plan view periphery of the male elements; and c) mechanically deforming the precursor nonwoven web with the forming members by placing the precursor nonwoven web between the forming members. The method forms a nonwoven web having a generally planar first region and a plurality of discrete deformations. The deformations form protrusions that extend outward from the first surface of the nonwoven web and a base opening adjacent to the second surface of the nonwoven web. The maximum interior width of the cap portion of the protrusions is wider than the width of the base opening.

An electric machine includes an electrical steel rotor having openings defining magnet pockets and outer side pockets, and having spaced apart axial stripes of increased compressive residual stress layers around a perimeter thereof. The outer side pockets and the perimeter form top bridges therebetween. Each of the axial stripes is aligned with one of the top bridges to strengthen outer edges of the top bridges.

A security document with unidirectional visual illumination is disclosed. A security feature is positioned within the document and not visible in normal ambient lighting conditions but becomes visible under specialized lighting conditions, for example in the presence of ultraviolet light. The security feature is constructible such that it is visible only from a single side of the security document, with the side being predeterminable regardless of the orientation of the specialized light.

In a method for producing a lamination stack for rotors and/or stators of electric motors or generators, laminations are punched from electrical steel, a light-activated adhesive is applied to at least one side of the laminations, respectively, and the adhesive is irradiated and activated with a light of a required wavelength immediately before the adhesive exits from an application unit. The laminations are then stacked to a lamination stack. An adhesive application device for carrying out the method has at least one application unit with at least one valve for discharging an adhesive. At least one radiation source is arranged in a region of the valve and emits a radiation and directs the radiation to the adhesive provided in the region of the at least one valve.

An apparatus and method for bonding sheet metal parts to a laminated core in which sheet metal parts are punched from an electrical steel strip, the punched sheet metal parts are stacked and bonded at least integrally to form a plurality of laminated cores, and in order to facilitate the separation of the integrally bonded sheet metal parts into laminated cores, a separating agent is provided at least between two stacked sheet metal parts in that with the punching stage for punching the sheet metal part, the separating agent is both punched from a separating agent support and provided to the sheet metal part. In order to embody the application of a geometrically accurate separating agent in a reproducible and simple way, it is proposed that the separating agent be punched from the sheet-like separating agent support that is supplied below the electrical steel strip.

A method of forming a composite preform containing multiple laminates is disclosed. The method may include providing a first sublaminate comprising stacked fibers woven into a fabric; providing a second sublaminate comprising stacked fibers woven into a fabric; joining the first sublaminate and the second sublaminate forming a component comprising a region of discontinuity sandwiched between the first sublaminate and the second sublaminate; rigidizing the component; and softening the region between the first sublaminate and the second sublaminate. In illustrative embodiments, the method may include manipulating the region of discontinuity between the first sublaminate and the second sublaminate to reduce the incoherence between the sublaminates by moving fibers from the sublaminates through at least part of the region between the first sublaminate and the second sublaminate.
