A roll (16) of structural material for use in the manufacture of large composite structures such as wind turbine blades is described. The roll (16) comprises an elongate stack of structural layers (10) fastened together and wrapped around a reel (14). The reel (14) comprises a plurality of mutually spaced supports (50) about which the stack is folded into a rolled stack. Sections of the rolled stack between the supports are substantially unsupported by the reel and are held in a slack state in order to prevent wrinkles from forming in the rolled stack.

The present disclosure describes a blood oxygenator that includes a checkerboard layout of fluid (e.g., blood) and gas (e.g., oxygen) channels. When viewed as a cross-section through each of the channels of the oxygenator, the checkerboard configuration includes alternating gas and fluid channels in both the x-axis (e.g., in-plane) and in the y-axis (e.g., out-of-plane) directions. The oxygenator described herein reduces manufacturing complexity by using first, second, and third polymer layers that include asymmetrical channel designs. The channel designs include "open" gas channels, which are exposed to the ambient atmosphere. The oxygenator is placed within a pressure vessel to drive gas into each of the open gas channels, which in some implementations, negates the need for a gas manifold.

The present invention relates to an apparatus and method for making an absorbent structure for an absorbent article, comprising a supporting sheet and thereon an absorbent layer, the absorbent layer comprising an absorbent material. According to the present invention a first moving endless surface is provided which has one or more substantially longitudinally extending first mating strips, and at least one further auxiliary moving endless surface is provided which acts against the first mating strips. Pressure is applied between the first moving endless surface and the auxiliary moving endless surface to the first and second supporting sheets at least within a part of the area of the channels, so as to adhere together the first and second supporting sheets.

The solar panel is manufactured by provision of a stack of foils on top of a carrier table. Individual solar cells are provided between a first and a second foil of thermoplast material. An interconnect foil is present between the first foil and the carrier table, connections to the solar cells extending through the first foil. At least one module of electronic components is integrated into the solar panel. The carrier table and the interconnect foil are provided with one recess, so as to leave space for the encapsulated components. This allows the assembly of the module to the carrier table prior to the assembly of the first and second foil and the solar cells. Contact pads on the interconnect foil for connection to the module are defined in annular ring around said recess. The annular ring is filled with a filling material so as to limit spreading of thermoplast material. An apparatus comprising a carrier table with a suitable recess is also provided.
