Title: POCKETED SPRING COMFORT LAYER AND METHOD OF MAKING SAME
Abstract:
A comfort layer (16, 16a, 50, 56, 56a, 56b, 132, 140) for a bedding or seating product (10) has slow-acting pockets (44, 44a, 84, 84a) characterized by the individual springs (28) of the comfort layer (16, 16a, 50, 56, 56a, 56b, 132, 140) being pocketed with either semi-impermeable or impermeable fabric. Each seam (30, 70) joining opposed plies (22, 23, 24, 25, 64, 65, 66, 67) of fabric around each of the coil springs (28) of the comfort layer (16, 16a, 50, 56, 56a, 56b, 132, 140) may be segmented, allowing air to flow between the segments (26, 68), thereby increasing the luxury "feel" of the comfort layer (16, 16a, 50, 56, 56a, 56b, 132, 140). The method of making the comfort layer (16, 16a, 50, 56, 56a, 56b, 132, 140) includes compressing the springs (28) and creating pockets (44, 44a, 84, 84a) with a welding horn (32, 32a, 72, 72a) and an anvil (42, 42a, 74, 74a).
