    摘要: In general, techniques are described for the creation and execution of accurate models for the manufacture of complex, multi-layered materials. The techniques may be used to calculate variations of a process parameter within the material during the manufacturing process. A method comprises receiving segment data that partitions a manufacturing process into a set of segments having at least one layer of a material. For example, the segment data may partition the manufacturing processes along a path traversed by the material within the manufacturing process. The method further comprises receiving curvature data for the layers, and calculating values for a process parameter through the layers of the segments as a function of the curvature data. The method may comprise invoking a one-dimensional model, such as a one-dimensional finite difference model, to calculate the values for the defined segments and layers.

    摘要: A product stacking apparatus and method employs one or more stations, each including a stationary stacking platform or a conveyor upon which spaced-apart pucks are coupled for travel thereon. A product delivery apparatus drives one or more movable webs to which segmented product sheets are removably affixed. The product delivery apparatus includes one or more rotatable lamination interfaces associated with each of the stations for transferring product sheets from the webs to the pucks on a repetitive basis to produce a stack of product sheets on the respective pucks. Each of the segmented product sheets may define all or a portion of an electrochemical cell, all or a portion of a pad including layers of film or sheet material, wherein a portion of each of the layers is provided with a bonding feature, or all or a portion of a pack comprising layers of medical dressing. A puck need not be in motion during the transfer of the product sheet from the lamination roll to the puck. The puck may or may not be attached to a conveyor, but the conveyor need not be in motion during the lamination or stack building process. In this case, a roller is moved across the puck and simultaneously rotated so a point on the surface of the roller interfaces with the puck at the same location on each pass.
