Abstract
A device for opening envelope bodies so that they can be filled has opening fingers coupled to actuator means for moving the fingers between a retracted position and an opening position in front of each envelope in a filling position. The device includes a preassembled assembly (30) formed on a "finger" shaft (35) which carries the fingers (30) which are mounted to rotate freely thereon and which are positioned longitudinally therealong and retained resiliently by abutment means, and secondly a guide plate (10) mounted relative to the assembly (30) to oppose the abutment means by constituting a sliding surface for the fingers when they are actuated.
