The machine for filling No. 1 post crates (2) with 120 mm x 235 mm envelopes (4a) comprises a conveyor belt or roller conveyor which feeds them into the crate while it rests on its base or one narrower end. The instantaneous length (L) or height of the stack is measured and the crate or conveyor moved so that envelopes are continuously fed in at the end or top of the stack.
