Abstract
A bobbin assembly having a base wall, a center post projecting away from the base wall in cantilever fashion, a peripheral wall assembly which extends at least partially around the center post, a hook assembly and at least one of a) a thread cutting slot and b) a knife edge on the bobbin assembly. At least a part of the hook assembly is rotatable around a first axis to engage a thread and cause an engaged thread to be formed into a loop as an incident of the at least part of the hook assembly rotating around the first axis. The at least one of the a) thread cutting slot and b) knife edge on the bobbin assembly severs a thread which is formed in a loop by the hook assembly as the at least part of the hook assembly is rotated around the first axis in operation, which loop, if constricted, would wrap against the center post.
