Abstract
In the proces of defining quilted fabric, non-stretchable, stretchable and interior layers of materials are wound on separate rollers. Then the layers are positively fed from the rollers to a bi-directional acting swing assembly wherein non-stretchable and interior materials are provided with zero elongation and the stretchable layer with 50 to 100 per cent stretch. Next, the arranged layers are sewn in sets of sinusoidal-like seam patterns. Finally the stretched layer is permitted to relax to a natural state wherein a series of puffs are formed in rows across the layer normal to stretch direction of the stretchable layer. Result: columns of puffs of even numbered rows are aligned with each other but are laterally offset with respect to puffs of odd numbered rows by a constant amount.
