ABSTRACT:
The scrap ejector has a relatively long and thin body made of stainless steel or other resilient and durable material. The leading end portion of the body overlies and is secured to the outer surface of the die roll. In its undeflected condition, the trailing end portion of the body is spaced radially from the die roll. In one embodiment the body has a pad of compressible elastomer upon the surface thereof distal from the die roll, and in another embodiment the body has an arcuate portion projecting from the aforesaid surface of the body. During passage of the scrap ejector through the nip between the die and anvil rolls engagement between the anvil roll and the resilient pad (in the first embodiment) or the arcuate portion (in the second embodiment) deflects the trailing end portion of the body to a position wherein its terminal end is closely adjacent the surface of the die roll and the leading surface of the cutting rule which trims the leading edge portion of the paperboard stock. Upon passage from the nip, the leading end portion of the body springs outwardly and ejects from the apparatus the scrap material produced by the trimming operation. The edges of the body preferably are rounded and smooth.
