Trim Ejector for Ejecting the Trim Produced by a Rule of a Rotary Steel Rule Die Apparatus or the Like

A rotary steel rule die apparatus comprising:

• a die cylinder rotatably mounted to a frame including a die board provided with a plurality of steel rules mounted to the die board so as to define a die cutting tool;
• an anvil roll mounted to the frame so as to be positioned parallel to the die cylinder and so as to define a sheet receiving gap therebetween;
• each of the plurality of steel rules producing a respective trim following a passage of a sheet in the sheet receiving gap;
• the improvement wherein the apparatus further comprising:
• at least one trim ejector mounted to the die board adjacent one of the plurality of steel rules for ejecting the respective trim produced by the one of the plurality of steel rules, 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 secured the leaf-like body to the die board so that the ejecting edge of the leaf-like body is positioned adjacent the one of the plurality of steel rules 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.

An ejector for ejecting a sheet in a rotary steel rule die apparatus, the rotary steel rule die apparatus further comprising a die cylinder including a die board provided with a matrix of steel rules and an anvil roll positioned parallel to the die cylinder so as to define a sheet receiving gap there between, the ejector comprising:

• a leaf-like body defining a sheet-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 sheet-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 is in the sheet receiving gap, 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 sheet and causes an ejection of the sheet.
