FIELD: transport.
SUBSTANCE: proposed set of inventions relates to written correspondence automatic processing. Device to stack flat articles O1-On edgewise contains frame 10 with support pad 24, 24' installed on it where the stack P is formed of flat articles O1-On as the flat articles O1-On are fed and moved edgewise one by one by pushing force in main direction D with overcoming the force of stack holding element 18 located at front end of this stack. Stack holding element 18 is made movable relative to the frame 10 and is connected with devices made so that it could act by return force on a stack of flat articles O1-On thus providing its holding. Support pad 24, 24' contains at least one smooth band 24, 24' wrapped around row of rollers 221, 22n, installed on the frame 10 being capable of free rotation, and is installed with possibility of free movement relative to the frame 10 in main direction D. Movement in this direction D is synchronised with holding element 18. Additionally, synchronisation element 26 is installed, separate from support pad 24, 24', connected in translational movement in main direction D at the same time with holding element 18 and with support pad 24, 24'. The synchronisation element 26 represents toothed band 26 installed with possibility of free movement on the frame 10. Holding element 18 contains projection 18' made capable to interact with two adjacent teeth of this toothed band 26. Also, post sorting machine is proposed containing described device to stack flat articles O1-On.
EFFECT: set of inventions provides laying flat articles in stack of significant length without its collapsing, convenient use.
