  • Patent number: 7128817
    Abstract: A feed belt for strip-shaped elements includes a belt body and a plurality of fingers, the fingers being previously fabricated and coupled to the belt body at constant pitches. The belt body includes fitting openings and slits formed at one side of the fitting openings. Each fitting opening serves to be coupled with a fitting portion and an elastic hinge portion formed at one side of each finger. Each slit serves to be coupled with a bent gripper portion formed at the other side of the finger so as to allow movement of the bent gripper portion. The fitting portion and the elastic hinge portion of the finger, to be coupled into the fitting opening, are integrally formed. The bent gripper portion to be fitted into the slit is integrally connected with the elastic hinge portion through a direction conversion portion.

  • Publication number: 20040104112
    Abstract: Disclosed herein is a feed belt for strip-shaped elements. In case of a conventional feed belt configured so that its belt body and fingers are integrally formed, the feed belt has to be wholly replaced even if a part of the fingers is damaged or deformed in use, resulting in uneconomical problems. Further, the fingers must be simultaneously pressed toward each other into horizontal pressing directions for loading/unloading of the strip-shaped element, resulting in a complexity in the structure of associated peripheral devices. Even in case of another conventional feed belt configured so that its fingers are separably coupled to its belt body, the fingers have to be pressed upward in operation, resulting in a complexity of associated devices.
