Legor Aster

The Legor-aster system allows to build sewn book blocks from web printed signatures; it works in line with the press just after the folding station. The unit is suitable for medium to high speed presses and delivers high quality sewn books.

The Legor pressing stacker receives a stream of freshly printed and folded signatures, presses them one by one and stacks them up to a height of 100mm.

Complete piles are ejected onto a transport channel, conveyed in a safety buffer and finally loaded into the infeed hopper of an Aster book sewing machine. The stacks are automatically sewn, separated from one another and delivered on a conveyor for their further finishing.
