Abstract
A flyer bobbin for receiving roving having an elongated cylindrical barrel with a longitudinal groove provided in the surface thereof. An elongated resilient clamp member is carried within the groove with one end secured in the groove and the other end extending therefrom. A flat area is provided on the surface of the bobbin directly adjacent one end of the groove directly under the outwardly extending portion of the resilient member. A similar resilient clamp member and groove is provided on the opposite side of the barrel. Thus, by using two clamp members, one of them always faces the service side of the machine.
