ABSTRACT:
An improved suction feeder, particularly for printing machines is disclosed, wherein higher feeding and printing speeds are made possible.
The main features of the invention is that in the body of the suction feeder is a small conduit channel and an air filling small channel which connect an inleading small channel for the bringing of pressurized air into an empty space over a small piston. In the said small conduit channel is formed a pressure spring in the upper part of said small conduit channel, and a seat in which a small ball is placed on the other end. The above described suction feeder works on the principle of the difference of air pressure above and below the small piston. While individual paper sheets are being lifted from a pile of sheets, the pressurized air is led into the empty space over the small piston, by which it instantaneously neutralizes the remaining depressurized air, leading to an instantaneous loosening of the paper sheets.
