The present disclosure is directed to lamina(e) comprising cube corner elements, a tool comprising an assembly of laminae and replicas thereof. The disclosure further relates to retroreflective sheeting.

A flexible packaging laminate has built-in opening/reclose and tamper-evidence features by forming the laminate from an outer structure joined in face-to-face relation to an inner structure. Score lines are formed in both structures to enable an opening to be formed through the laminate by lifting a flap or the like out of the plane of the laminate. The score line through the outer structure defines a larger opening than the score line through the inner structure, such that a marginal region of the outer structure extends beyond the edge of the opening portion of the inner structure. A pressure-sensitive adhesive is used to re-adhere the marginal region to an underlying surface of the inner structure adjacent the opening through the laminate. The outer score line includes at least one tear portion that is torn through upon initial opening, thus indicating the package has been at least partially opened.

An optical element includes a substrate, a plurality of reflection layers disposed on one side of the substrate, an absorbing layer disposed on a side of the reflection layers that is opposite to the substrate, and an oxide film that covers the absorbing layer and portions between any two adjacent reflection layers. The reflection layers are arranged in a striped manner in plan view. The oxide film is made of an oxide of a material contained in the absorbing layer.

An improved method of manufacturing an equine protective covering includes applying a stamp comprising a profiled shape with a predetermined temperature and pressure to the interior side of the cushion assembly such that concurrently: the first synthetic fabric layer and the second neoprene layer are permanently bonded; the second neoprene layer is plastically deformed such that the profiled shape of the stamp is permanently transferred to the second neoprene layer; and the plastic deformation of the second neoprene layer is such that the perforations remain open.

An optical element includes a substrate, a plurality of reflective reflection layers on the substrate, and an absorbing layer over the reflection layers. The reflection layers are arranged in a striped manner in plan view. The absorbing layer absorbs polarized light oscillating in the direction in which the reflection layers extend. The optical element also includes an oxide film on the substrate between the reflection layers and on the absorbing layer. The oxide film is formed by oxidizing the absorbing layer.

A device for dynamic length compensation when embossing a film strip includes: an embossing point; a roller for slip-free transport of the film strip; and a guide channel arranged between the embossing point and the roller. The guide channel has a guide surface movable between a first position and a second position. A path length of the film strip between the roller and the embossing point in the first position of the guide surface is greater than a path length of the film strip between the roller and the embossing point in the second position. The film strip, in the first position of the guide surface in the guide channel, is conveyed from the roller to the embossing point. The guide surface is moved from the first position to the second position during the embossing of the film strip.

A polymeric film has an orthogonal length and width. The polymeric film includes a substrate and a plurality of fins extending away from the substrate and substantially coextensive with the substrate along the length. The fins are arranged across the width. Each fin in at least a majority of the fins includes a first portion extending from the substrate to a tip of the fin opposite the substrate; and a second portion extending from the tip of the fin toward or to the substrate. The second portion is attached to the first portion proximate the tip and separated from the first portion proximate the substrate along at least a portion of the length. The first and second portions have different respective first and second compositions.

A pressure-sensitive adhesive is used to re-adhere the marginal region to an underlying surface of the inner structure adjacent the opening through the laminate. The outer score line includes at least one tab positioned within a heat seal region of the laminate.

Provided are a vehicular interior member manufacturing method and an airbag rupturing groove manufacturing method which can form an airbag rupturing groove excellent in invisibility even in a vehicular interior member having a hard substrate layer, while performing a proper control of the thickness of the remainder of the airbag rupturing groove to be formed. The vehicular interior member manufacturing method is characterized by protruding a metal blade having an edge flattened at least partially against a forming face of the rupturing groove, from a back side of the vehicular interior member and partially into the skin layer wherein a thickness of the skin layer into which the metal blade has not protruded corresponds to a remaining thickness of the skin layer, and confirming whether or not the metal blade is detected at a second detecting position while the metal blade is not detected at a first detecting position.
