Scissors
Scissors are used for high traversing
speeds. This allows an even extension
of all elements across the whole
extension length. As a result, the
folds are less strained and the
durability of the bellows is
prolonged.
Rollers
Rollers are used in large and heavy
bellows with extension limiters. They
minimize friction and ensure excellent
running properties.
Half-scissors
The advantage of half-scissors is
that the individual elements can be
extended successively depending
on the necessary extension length.
Since the folds are not loaded up to
the theoretically possible extension
limit, the durability is also longer.
Bellows with large extension lengths are composed of various elements which
are connected by intermediate frames. Regarding the choice of material for
frames and bellows, we can meet nearly all customer requirements.
Intermediate steel frames
Intermediate steel frames are used
to connect the various elements,
especially when extension limit
systems are required. The inter-
mediate frames are fastened to the
bellows with a clamping rail. The
intermediate frames can be guided
by either plastic or brass rollers or
guides.
Guide frames
The guide frames provide the bellows
with the necessary stability and enable
a precise operation, even at high
speeds. They are made from PVC
and are directly attached to the cover.
The shape of the frames is adapted
by Hennig to the design required.
