The Concept of
the Hoffmann-Dovetail Key
Hoffmann Dovetail Keys are
the invention of Hoffmann Maschinenbau GmbH Germany.
The dovetail shape is a proven
mechanical feature, already used in many avenues of industry.
Hoffmann have adapted this feature to create the double dovetail Hoffmann
Key. Not only accepted in the woodwork industry, but requested and
required to maintain production levels of leading manufacturers.
Proven Feature - The Brilliant System
The dovetail shaped Hoffmann Key is a classic proven mechanical feature,
recognised for its precision and performance - not only in mechanical
construction but also in woodworking.
function makes the Hoffmann Key the ideal jointing method: Because of the
precise double dovetail shape of the Key and the exact routed dovetail
slots the jointed parts are drawn together to form an accurate, secure and
permanent joint. A joint is produced which is locked together by
configuration and has no further requirement for alignment aids or
clamping systems. In some situations, glue is not required as the
strength of the joint is adequate.
The joints can be successfully made
as square butt joints or any required angle.
Reliable, substantial and versatile
Without doubt, solid and secure
Up to 70% time saved (compared with other systems of joining)
We're found in
the best joints!
Whether for industrial
use or craft workshops:
Hoffmann Keys are efficient and basically problem-free, either as single
joints or as completed units.
The work-pieces are held together
firm and fast by the serrated sloping inner sides of the dovetail keys.
These serrated sides grip into the wood drawing the adjacent parts firmly
together. The grip of the key prevents the sliding of the jointed parts.
The principle is seen at its best in
mitres and designed to create pressure to the surfaces.
a few seconds
- A dovetail slot is routed in the
faces of each part
- These are placed together and a
Hoffmann double dovetail key is inserted...finished!
- All jointed parts can immediately
be further processed without waiting for glues to dry
