Abstract

A device for picking up a sheet trailing edge from an upstream cylinder and transferring the sheet trailing edge to a gripper system of a downstream drum, as viewed in sheet travel direction, includes a sucker guide mechanism having a movably mounted sucker carrier whereon sucker heads subjectible to an application of vacuum or suction air are disposed. The sucker carrier is constructed as a tubular part having a longitudinal axis and being movable perpendicularly to the longitudinal axis thereof. The tubular part is formed with a vacuum or suction air duct extending in the interior thereof and is formed of carbon fiber-reinforced plastic-material laminate.
