Hold-down for use on feed table of printing press

摘要

A sheet feeder for feeding of sheets from a pile to the inlet gripper of a printing press includes a downwardly angled feed table extending between the pile and the press, sheets being fed in succession across the table. A periodically interposed front stop stops the sheet at the end of the table in position for pick-up by the gripper in the press. A side guide at the edge of the table and extending upwardly a short distance therefrom positions the lateral edge of the sheet. A wiping assembly wipes the sheet toward the side guide as it settles against the front stop. To keep the sheet on the table a flexible leaf spring presses downwardly on the sheet in the region of the side guide. A holder engages the upstream end of the spring for holding it at a shallow angle and in a slightly sprung condition. An articulated joint between the holder and the spring permits the downstream end of the leaf spring to swing laterally with the sheet into angled position as the sheet undergoes lateral wiping movement toward the side guide.
