Dependent upon the die chosen Designed for 2, 3, or 4-layer sheet production, the layer confi guration can be changed via use of different fl ow selection cartridges. Layer percentages can be adjusted by adding or removing fl ow channel modules. Designed for 5- to 9-layer sheet production, this type of feedblock allows layer percentage control externally, using fl ow control pins or adjustable vanes for each layer. The layer confi guration can be changed via use of different fl ow selection cartridges.
