DEFINITION

Classification: 139/457

Circular, progressive shedding:

(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.

(1) Note. A loom of this subclass performs an operation which may be described as circular weaving with progressive shedding.
