1. An improved fiber tow laying and compacting device for making a composite fiber article comprising:

  • a. a housing for carrying a segmented presser member andb. a segmented presser member for laying and compacting fiber tows comprising a plurality of independently, linearly movable individual presser elements in a stacked side-by-side parallel array supported in the housing, each presser element comprising an outer periphery extendible from the housing toward a workpiece surface and an elastic material layer on said periphery independent of adjacent elastic material layers on adjacent periphery of adjacent presser elements of the segmented presser member, said linearly movable individual presser elements movable along an axis extending through the center of the presser element and intersecting the area of contact between the presser element and the workpiece surface and wherein the presser element further comprises a means for providing rotary motion to the element and wherein the arrayed presser elements of said presser member cooperatively function to substantially exclude penetration of the fibers of the fiber tow between the presser elements during laying and compacting of the fiber tows.
