Mechanism to decelerate and/or accelerate printed sheet movements, at a printing press, has them moving between two units each with a cam at a planet wheel rotating within a hollow wheel

摘要

The mechanism (10) to slow down and/or accelerate the movement of printed sheets, or printed specimens separated from a web, has at least two units (11,12) with the printed matter moving through (13) between them with a steady increase or decrease from an initial movement speed. Each unit has a cam (14) at a planet wheel (16) rotating at a point (15) within a hollow wheel (17).
