  • Patent number: 5074968
    Abstract: An apparatus for stripping starting sheets of the present invention comprises stripping rods which are horizontally disposed at positions opposite to the right and left sides of both surfaces of a mother board, which is stripped at the upper end and is suspended and transferred by a trolley conveyor, so that they can be inserted into the stripped upper end when the mother board reaches a predetermined stripping position; elevating members which respectively carry the stripping rods through attachments so as to upwardly and downwardly move the stripping rods at small distances from the surfaces of the mother board between an upper position above the stripped upper end of the mother board and a lower position under the lower ends of the starting sheets; and a driving member for upwardly and downwardly moving the elevating members in synchronism with each other.
