multiplying element first slices the ab structure vertically and subsequently spreads the melt horizontally the flowing streams recombine doubling the number of layers an assembly of n multiplier elements produces an extrudate with the layer sequence ab x where x is equal to 2 n and n is the number of multiplying elements to form a multilayer stack as depicted in the right most portion of fig1 a fig1 b is a cross sectional view of a fiber with multiple layers produced by co extrusion it being recognized that the layers in a co extruded fiber may not be flat as depicted in fig1 b rather the individual layers may be curved or have other configurations but will form distinct regions in the fiber co extrusion with the use of feedblocks and multipliers is a well understood technique in chemical engineering see for example u s pat no 7 936 802 u s pat no 7 141 297 u s pat no 7 255 928 u s pat no 7 052 762 u s pat no 3 565 985 and u s pat no 3 051 453 each of which are herein incorporated by reference layered melt blown fibers made using feed block technology are described in u s pat no 5 176 952 and u s pat no 5 207 970 both of which are herein incorporated by reference the examples below show the combination of polyethylene pe and polycaprolactone pcl being combined as multiple layers in electroprocessed fibers according to the present invention however many different polymers.
