Abstract: The present invention relates to carrying apparatus manufacturing processes. One embodiment of the present invention relates to a method for coupling materials of dissimilar stiffness on a carrying apparatus. The method includes adhering a cover fabric member to a base fabric member of different stiffness using applied sandwich pressure and high frequency transmission. The high frequency transmission may include translating the fabric members so as to sequentially straddle a high frequency wheel along a perimeter of the cover fabric member. An adhesive agent is disposed between the cover fabric member and the base fabric member. The adhesion between the fabric members is configured to exceed a peel test tolerance of ten pounds. In addition, optional acts of applying high and low temperatures may be included to pre-tack the cover fabric member to the base fabric member.
