Abstract
A shedding apparatus for waste selvage includes a pair of first swing levers and a pair of second swing levers for forming an open shed of selvage yarns. The drive force to the swing levers is transmitted by cranking through a drive shaft which is coaxial with the sun gear of a planetary gear mechanism. The crank mechanism using the cranking includes a crank, first end of which is fixedly connected to the drive shaft for rotation therewith, a drive lever for transmitting a rotational force to the swing levers, and a connecting rod connected between second end of the crank and the drive lever. A ratio between an eccentric distance of the crank and a length of the drive lever is less than 1.
Claims4
A shedding apparatus for waste selvage in a loom having a leno selvage forming apparatus of a planetary gear type including a sun gear and a pair of planetary gears which revolves around the sun gear, wherein the waste selvage is formed at positions outward of leno selvages and the waste selvage is to be removed from a woven fabric, the shedding apparatus for waste selvage comprising:
- a pair of swing levers for forming an open shed of selvage yarns, wherein drive force to the swing levers is transmitted by a crank mechanism through center axis of a rotating support supporting the planetary gears.
