Abstract
Combination quilted patterns of which at least one component pattern is continuous are sewn on a multi-layered web of material with the sewing heads on one bridge as the material is advanced longitudinally. The bridge might or might not also move longitudinally. Simultaneously, different patterns, either continuous or discontinuous, are sewn with another independently moveable bridge. The continuous patterns extend substantially the lengths of quilted panels on a web, and may extend without thread cuts or tacks along the web across the lengths of more than one panel. One pattern can be changed while the other pattern continues along the web. New patterns, intermediate quilted products and methods for quilting them are provided.
