| 摘要 |
The invention consists of an attachment for a sheet material transporting system such as the ejector system of an off-set printing press, wherein the ejector system includes a rotating ejector drum, an idler wheel in frictional engagement with said drum adjacent each end thereof and being supported by a shaft rotatably disposed axially paralled to said drum and being rotatably driven by said idler wheels. Said attachment consists of a frame composed of paralled spaced frame members and an idler wheel rotatably disposed between said frame members at each end thereof. One of said idler wheels is coaxially disposed on said shaft and is rotated thereby. Said frame includes means for attaching said attachment to the off-set press for lateral adjustment to permit the idler wheels to contact the sheet material being ejected adjacent the edge thereof.
