  • Patent number: 8166858
    Abstract: A trim ejector for ejecting the trim produced by a steel rule of a rotary steel rule die apparatus includes a die cylinder having a die board provided with the rule and an anvil roll positioned parallel to the die cylinder to define a sheet receiving gap therebetween. The trim ejector has a flexible 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 flexible body for securing the flexible body to the die board to position the ejecting edge of the flexible body adjacent and parallel to the rule, and a compressible biasing member secured to the flexible body on a side opposite the trim-ejecting surface. The compressible biasing member forces the flexible body to a neutral position, corresponding to no tension being applied to the stem portion, when the flexible body is moved away from the neutral position under passage of a sheet in a sheet receiving gap.
