Abstract

A delivery mechanism for a single or double folder in which underneath each individual folder a pair of fan shafts are mounted to which fan paddles may be removably secured so that, if both folders of a double folder are in operation, one fan shaft of each pair is left without paddles and only the paddles on the other fan shafts receive the folded products from the associated folders and deposit them on separate conveyer belts, while when one folder of a double folder including the associated fan shafts is stopped and all webs are passed from the press to the other folder or when only one folder is provided, one half of the usual number of paddles of one fan is secured to each of the other pair of fan shafts but in a staggered relation to each other so that these fans will then alternately deposit the products upon one conveyer belt and then upon another adjacent conveyer belt.

Claims

1. A deliVery apparatus for printed products for use with folding apparatus of web-fed rotary printing machines wherein there are double folding apparatus, there being delivery apparatus for each folding apparatus, one of the folder'"'"''"'"'s delivery apparatus being spaced apart from the other folder'"'"''"'"'s delivery apparatus and transfer means between said spaced apart delivery apparatus, said delivery apparatus for each folder comprising a pair of spaced apart fan shafts underneath said folder, paddles adapted to be secured to and removed from said fan shaft to be exchanged for each other whereby there are provided a pair of delivery fans having their paddles in the line of the printed products delivered from said folder, a substantially horizontal moveable conveyor underneath one of said delivery fans positioned to receive and move along printed products deposited thereon by said delivery fan, the other of said delivery fans having therebelow said transfer means between said spaced apart delivery apparatus, said transfer means being a substantially horizontal conveyor in line with said above referred to conveyor, said transfer conveyor serving also as the delivery conveyor for one of said other folder'"'"''"'"'s pair of spaced apart delivery fans, the other delivery fan of said other folder having its delivery conveyor in substantial alignment with said transfer conveyor.

2. A folder delivery mechanism according to claim 1 wherein there is only one press feeding to said two folders, one of said folders having its two spaced apart delivery fans delivering the printed product from said one folder alternately to said conveyor under one of said fans while the other cooperating delivery fan delivers to said conveyor therebelow serving as said transfer conveyor, and the other of said folders running and delivering its products to its first fan shaft equipped with its paddles which deliver said products to the conveyor therebeneath, said last conveyor also receiving the products conveyed by said transfer conveyor.
