Abstract: A method of installing a sleeve on a die cylinder of a die cutter, the sleeve having a thickness that reduces a gap between the die cylinder and an anvil cylinder of the die cutter. A first locking component of an anvil cover is secured in a locking component receptor of the anvil cylinder and the anvil cylinder is rotated until a second locking component of the anvil cover is pressed by the sleeve to couple with the first locking component in the locking component receptor of the anvil cylinder.

Abstract: A container or pod for securely housing a watercraft (e.g., a surfboard) is described. A board pod assembly is configured to enclose or encompass a surfboard using components composed of sustainable recyclable materials that can be reused or recycled. The board pod assembly may include a corrugated paper-based frame shaped and sized to receive the board within an inner cavity formed by the frame. The frame may be configurable between a ring-shaped configuration (e.g., for use in enclosing the board) and a folded configuration (e.g., for storage purposes when not enclosing the board). The board pod assembly includes a bottom lid configured to couple to a surface of the frame. The assembly further includes a top lid configured to couple to a surface of frame (e.g., an upper surface of the frame) opposing the surface to which the bottom lid is attached.

Abstract: A paper-based watercraft board (e.g., a surfboard) and a method of making a paper-based watercraft template (i.e., a blank or core) and watercraft board are described. The surfboard template composes paper-based materials to produce sustainable and recyclable alternative to traditional foam core surfboards.

Abstract: A sleeve for attaching to a cylindrical platform of a die cutting machine. The sleeve includes a first elastic member and a second elastic member. The sleeve may be arranged in a cylindrical configuration by aligning a first abutting surface of the first elastic member to a second abutting surface of the second elastic member. The first elastic member and the second elastic member can be mounted on a cylindrical platform without the need for a locking mechanism to secure the sleeve onto the cylindrical platform.

Abstract: A protective cover includes a padding layer and at least one backing layer comprising a network of fiber-reinforced plastic (FRP) threads, wherein a surface of the at least one backing layer is substantially rectangular comprising a first side, and wherein a plurality of the FRP threads are arranged along a direction that is oblique relative to the first side.

Abstract: A die cutter includes an anvil cylinder, a die cylinder, and a sleeve that is mounted on the die cylinder for generating a pressing force on an anvil cover to force a locking component of the anvil cover into a locking component receptor of the anvil cylinder.

Abstract: A cylindrical sleeve for attaching to a cylindrical platform of a die cutting machine, the cylindrical sleeve including a first elastic member and a second elastic member substantially identical to the first elastic member, each of the first elastic member or the second elastic member comprising an inner surface, an outer surface opposite to the inner surface, a first abutting surface, a second abutting surface opposite to the first abutting surface, a first end surface, and a second end surface opposite to the first end surface, wherein the first abutting surface and the second abutting surface are planar surfaces, wherein the cylindrical sleeve is formed by aligning the first abutting surface of the first elastic member to the second abutting surface of the second elastic member, and aligning the second abutting surface of the first elastic member to the first abutting surface of the second elastic member, and wherein an inner surface of the cylindrical sleeve formed by the inner surfaces of the first and s

Abstract: An anvil blanket is molded urethane sheet material and formed with a plurality of interlocking fingers at mating opposing blanket ends and includes a depending projection which mates with a channel in the anvil about which the blanket is wrapped. A urethane insert having a hardness greater than the blanket material is molded embedded in the blanket to form a portion of the fingers and a portion of the projection depending from the fingers. A woven fiberglass fabric provides support for the blanket and which fabric is molded to the blanket. The insert has a durometer greater than that of the blanket to minimize the formation of surface recess defects at the projection which might otherwise occur due to the increased thickness of material at the projection. The insert may have other properties different than that of the blanket material including rebound, modulus, and cut and tear strength among others for resisting the formation of blanket surface defects.
