A device for machining the edges of casting strands includes one machining tool each that can be brought into contact with a longitudinal edge of the casting strand, and at least one guide element for perpendicularly applying the machining tools to the longitudinal edges. Means are provided for moving the machining tools in parallel to the longitudinal edges of the casting strands, in order to modify the relative speed between the longitudinal edges and the machining tools.

A packaging insert (10) comprises multiple cellulose-based air-laid or solid foam substrates (20, 20A, 20B, 20C) having respective first and second main sides (22, 22A, 22B, 22C, 24, 24A, 24B, 24C). The packaging insert (10) also comprises a first paper-based sheet (30) attached to the first main sides (22, 22A, 22B, 22C) and a second paper-based sheet (40) attached to the second main sides (24, 24A, 24B, 24C). Edges (26, 26A, 26B, 28, 28B, 28C) of consecutive cellulose-based air-laid or solid foam substrates (20, 20A, 20B, 20C) facing each other are beveled edges (26, 26A, 26B, 28, 28B, 28C) and form an angle (a) between each other that is less than 90. At least one hinge section (50, 50A, 50B) is interposed between the beveled edges (26, 26A, 26B, 28, 28B 28C) of the consecutive cellulose-based air-laid or solid foam substrates (20, 20A, 20B, 20C). The packaging insert (10) is foldable in the hinge section(s) (50, 50A, 50B) and can be positioned within a packaging (80) to protect packaged goods. The invention also relates to a method of producing a packaging insert (10).
