High strength composite tape is prepared for laying in side-by-side strips upon a work surface by precutting the strips to a predetermined length and mounting the strips upon a carrier belt in longitudinally spaced relation to one another, so that the pressure foot of the machine applying the tape to a work surface may press to the end of one tape strip without pressing the end of the following tape strip. Improved laying of the tape is achieved by stretching a strip of tape entirely across the area on which the tape is to be laid before pressing any part of the tape against the work surface, and then pressing the tape against the surface while the tape is stretched across and adjacent the work surface. The tape is held and stretched across the work surface on supply and take up reels on opposite sides of the work surface, so that the reels need not move along the tape with the moving pressure foot.

The method of laying composite tape between boundaries defining an area of a work surface that is to be covered with a plurality of strips of tape to form a high strength structural part, comprising positioning tape supply and take up mechanisms at spaced points along a path that extends between a first boundary and a second boundary, stretching a strip of tape between said mechanisms adjacent said work surface with one end of said strip at said first boundary, pressing said strip against said surface along a pressure area of said tape strip, and moving said pressure area relative to one of said mechanisms along said tape strip and across said work surface area, while holding said tape strip stretched across and adjacent said work surface area.
