ABSTRACT:
Methods of making network structures include forming on one side of a sheet of thermoplastic polymer a plurality of parallel continuous main ribs and forming on the other side of the sheet in a different direction a plurality of parallel discontinuous tie ribs. The tie ribs are discontinuous in the areas where they cross over the main ribs to eliminate any increased thickness at the cross-over points of the main ribs and tie ribs. The ribbed sheet thus formed is drawn in either one direction or in two preferably perpendicular directions to open the sheet into a network structure and to orient the main ribs and preferably also to orient the tie ribs.
