NHG-70

SIGLOCH Book Block Nipping and Smashing Press NHG-70
– the first step towards the perfect book block
The fully automatic book block nipping and smashing press NHG-70 was
designed for processing thread-sewn book blocks and can be used
as a free-standing machine as well as an inline component in a production
line.
The use of an NHG-70 book block nipping and smashing press to level out
extreme incline in the joint area and at the head of a book block, is
prerequisite for a dimensionally stable book block.
The adjustment values can be transferred by Ethernet or entered via the
touch screen.

The NHG-70 is equipped with two pressing stations. In the first station, the
book blocks are pressed on both sides in the joint area, whereby the block
spine is fixed by spring-loaded pre-pressing jaws to prevent displacement of
the centre signatures during the pressing process.
The smashing station as the second pressing station presses the book block
throughout its entire surface.
This allows processing of difficult and instable paper qualities without any
problems. The NHG-70 ensures optimum preparation for the perfect book.
The NHG-70 can be used as an effective inline component in a book block
production line or as a free-standing machine in offline operation. A block
feeder for reliable feeding of thread-sewn book blocks is available to
achieve a speed of 70 cycles/min.
