Abstract

A newspaper stuffing apparatus wherein pockets which serve for reception of newspaper jackets and inner sections are transported along an endless path past a first feeder which admits openable jackets, past at least one second feeder which admits inner sections into opened jackets in successive pockets, and thereupon past an evacuating device which removes the thus assembled newspapers from successive pockets. Each pocket is associated with a retaining blade which is held at one end of the pocket during travel past the first feeder, which is moved by a spring into the pocket and clamps one-half of the opened jacket against one wall of the pocket during travel toward and past the second feeder, and which is retracted from the pocket not later than when the pocket reaches the evacuating device. Each blade is reciprocable along and is held against rotation relative to a guide shaft which is located behind the one wall of the respective pocket and can be rotated to move the blade against or away from one-half of the opened jacket in the respective pocket.
