1. A trim ejector for ejecting a trim produced by a rule of a rotary steel rule die apparatus, the rotary steel rule die apparatus further comprising a die cylinder including a die board provided with the rule and an anvil roll positioned parallel to the die cylinder so as to define a sheet receiving gap therebetween, the trim ejector comprising:

  • a leaf-like body defining a trim-ejecting surface extending between an ejecting edge and a stem portion;

    an anchor portion connected to the stem portion of the leaf-like body for securing the leaf-like body to the die board so that the ejecting edge of the leaf-like body is positioned adjacent the rule generally parallel therefrom; and

    a compressible biasing member secured to the leaf-like body on a side thereof opposite the trim-ejecting surface;

    the compressible biasing member being for forcing the leaf-like body to a neutral position corresponding to no tension being applied to the stem portion, when the leaf-like member is moved away from the neutral position by a sheet in the sheet receiving gap;

    whereby, in operation, when the sheet in the sheet receiving gap causes the rule to cut a trim from the sheet, the sheet exerts the tension on the stem portion and the biasing member is compressed;

    when the sheet exits the sheet receiving gap, the tension on the stem portion is released and the compressible biasing member forces the leaf-like body to its neutral position which then pushes onto the trim and causes an ejection of the trim.
