Extension arm for storing sheet on extension arm stack in e.g. feed offset rotary printing machine, has sheet guidance element that is spaced from carrier and circulating with carrier, where element is attached to system

摘要

The arm has a sheet transporting system (2) with a set of circulating pick-up carriers (2.1) each comprising a clamp. The clamp performs straight-line transportation of a sheet (4) at a front edge. A sheet guidance element (3) e.g. super blue cloth, is spaced from the carriers and circulates with the carrier, where the element is attached to the transporting system. The system has the carriers that are spaced from each other, where the element is arranged between the carriers. The element is driven with sheet transporting speed in a sheet transporting direction.
