Abstract
A hosiery inspecting and grading apparatus and a method of inspecting hosiery are provided that preferably has a boarding member arranged to mount a completed hosiery article thereon. The boarding member preferably is formed of a translucent material. An optical inspecting system is positioned adjacent the boarding form and is arranged to inspect a completed hosiery article mounted on the boarding member. The optical inspecting system preferably includes at least one light emitter positionally aligned with the boarding member to emit light through a predetermined portion of a completed hosiery article mounted thereon and at least one light detector positionally aligned with the at least one light emitter and the boarding member to detect the presence and absence of light traveling from the light emitter and through the predetermined portion of a completed hosiery article mounted on the boarding member so that presence and absence of defects in a completed hosiery article are thereby determined. The apparatus also has a grading and sorting system positioned downstream from the boarding member and the optical inspecting system and in electrical communication with the optical inspecting system to grade and sort a completed hosiery article responsive to electrical signals representative of presence or absence of defects received from the optical inspecting system.
