PROCEDURE AND ARRANGEMENT FOR DIRECT QUANTITATING OF FAILED ARCHITECTURE MACHINERY PRODUCED IN ROLLING STOCK MACHINERY

摘要

An apparatus for use in trimming the edges of folded signatures produced in web-fed rotary printing presses is disclosed. The signatures, which may exit from the printing press folder in an overlapping array, are supported from below by a conveyor belt or belts and are held from above by coacting hold-down belts. The signatures so positioned are moved past rotating chipping or cutting tools which remove excess material from the edges of the signatures. Either one or two chipping or cutting tools can be used and the apparatus is capable of trimming without reducing the production speed of the press which may be in the range of 40,000 signatures/hour.
