Abstract
A honeycomb structure in which pleats of a first pleated material are joined to corresponding pleats of a second pleated material by a plurality of ribbons is provided. The first and second pleated materials are positioned so that a pleat of the first pleated material is directed toward and in line with a corresponding pleat of the second pleated material. Opposite pleats of first and second material are thus facing one another and spaced a selected distance apart. A ribbon is affixed to each pair of opposed pleats so that a first portion of the ribbon is affixed to the pleat of first material, a second portion of the ribbon is affixed to the pleat of second material and the portion of the ribbon lying between the first portion and the second portion is disposed in the spaced between the first material and second material. The ribbon has one or more perforations located between the first portion and the second portion for lift cords to run through.
