Abstract

A newspaper stuffing apparatus wherein pockets having fixedly mounted and pivotable walls travel along an endless path below a plurality of feeders which propel jackets and inserts of newspapers into successive pockets. In order to prevent the jackets from rebounding upon impact against intercepting levers below the pockets, each pocket is equipped with two spring-biased braking members which bear against the corresponding pivotable wall and extend toward the associated fixedly mounted wall during introduction of a jacket so that the braking members frictionally engage the jacket but do not prevent it from moving its folded edge all the way into engagement with the intercepting levers. The braking members are retracted in response to movement of the pivotable wall away from the associated fixedly mounted wall to thus provide room for opening of the jacket preparatory to introduction of inserts.
