Hand looms are placed in this group.

457	. Circular, progressive shedding:

This subclass is indented under subclass 11. Subject matter wherein the special-type loom is one in which the warp is arranged in a circular manner and a section of the warp threads, of substantially the length of the shuttle, is moved to the open-shed condition and this open shed, in which the shuttle travels, is caused to move transversely of the warp, wherein the weft is laid in a circular course.
