| 摘要 | An exemplary embodiment provides a method of manufacturing a string of pocketed spring coils comprising: simultaneously making at least two spring coils; simultaneously transporting the at least two spring coils to a compressor: simultaneously compressing the at least two spring coils; simultaneously inserting the at least two compressed spring coils between top and bottom plies of a piece of fabric; welding the top and bottom plies of the fabric along an edge of the folded fabric parallel to the longitudinal axis of the fabric and opposite the folded edge of the fabric; welding the top and bottom plies of the fabric along lines transverse to the longitudinal axis of the fabric between each of the compressed spring coils to create a plurality of pockets, each pocket encompassing a compressed spring coil; and expanding each of the compressed spring coils within each of the plurality of pockets. | ||||||
