There is disclosed a lattice structure having a plurality of elongated parallel elements interconnected periodically by integrally formed ribs therebetween and a plurality of elongated filaments, each of which is embedded in and adhered to one of the elongated parallel elements. The structure is constructed by a method which includes the steps of molding the lattice structure from film or laminate belts, heating the filaments above the melting temperature of the molded lattice structure, joining the heated elements with the structure and solidifying the lattice structure adjacent each filament. The steps are performed by a machine which has rotating cylindrical drums in rolling contact to heat and mold the lattice structure therebetween, a heated cylindrical drum over which the filaments are passed to heat them to a temperature above the melting temperature of the molded lattice structure, contacting rotating cylindrical drums between which the molded elements of a lattice structure and the filaments are passed to join the filaments into the lattice structure and a pair of cooled rotating drums in rolling contact between which the joined structure is directed to solidify the combination.
