From the Louet web site:The Louet “Spring” loom is one of the most innovative cleverly
designed floor looms on the market today. It uses the Parallel
countermarch system for the harnesses and lams, which is easy to use
and simple to tie-up.
An exclusive feature to this loom is the patented moving breast beam
controlled by springs. The breast beam is attached to the loom in such a
way that it is free to move toward the harnesses when the shed is made
and then back toward the weaver when the shed is closed again. The
distance between the breast beam and the back beam actually changes
during weaving. With this system a larger shed can be obtained with
less tension increase in the warp and less effort from the weaver. The
advantages of this system are especially evident as you near the end of
the warp. Even when the end of the warp is very close to the
harnesses, a good shed can be made, thus saving yards and yards of
wasted warp over the life of your loom.
The moving breast beam also brings on exactly the same warp tension each
time the warp is advanced. The design of the loom includes a built-in
raddle on top of the castle and a storage shelf for keeping everything
you need within easy reach.
The heddles and tie-up cords are of the Swedish Texsolv system, which
make them quite strong and non-stretching. The Spring loom is available
in your choice of 2 weaving widths: 90cm (35 3/8”) or 110cm (43
1/4”). The “Spring” is made of lacquered beech and comes
ready-to-assemble with clear instructions and tools.
