at least one internally threaded cylinder on said frame,
said bolt being screwed into said cylinder, a worm wheel

button of the push buttons 168, 169 may be pushed only
after the other one has been covered.
Said compression operation, wherein the volume of

horizontal compression by means of said horizontally mov
able press plate 9, is a preliminary compression. There
fore, the supporting frame 2 as well as the package case
1 are moved to the press plate 7 of the hydraulic ap
paratus, i.e. the main compression mechanism, by the
rails 5 and the wheels 6, after said compression operation
or during said preliminary compression, through the ma
chine stand 4. Then, such material having thus been
compressed horizontally is compressed vertically in said
position by raising the press plate 7, the volume of the
material being decreased to a minimum for convenience
