Method and apparatus for reducing the impact speed of a printed product which is delivered to a fly pocket of a fly delivery wheel in a rotary printing press

摘要

The impact speed of a printed product which is delivered at a rapid rate into a pocket of a rotatable flywheel is reduced by engaging the printed product as it is propelled into the flywheel pocket adjacent its trailing edge. The invention includes a fly delivery wheel which may comprise a plurality of individual flywheel elements each having a plurality of flywheel pockets distributed around its circumference. The flywheel pockets open radially and as the openings of each pocket are moved around during the rotation of the flywheel the printed product is delivered into the opening and it moves at high impact speed into the pocket space. A cam is rotatably mounted adjacent the flywheel and adjacent a ring which is carried on a rotatable shaft and the printed products are delivered between the rotatable cam plate and the ring and into the pocket. The cam plate advantageously includes one or more cams having tips with elastic portions which move during rotation of the cam into close contact with the rings. The cam plates are advantageously rotated in an opposite direction to the flywheel and the cams engage the printed products with the rings and reduce the impact of the products into the flywheel receiving pockets.
