Introduction
Megado’s countermarch action produces a perfect shed automatically
The Megado is not literally a countermarch loom although it has all the advantages of one. In
countermarch looms, the shafts move both up and down so that tension on both raised and
lowered warp threads is equal. With the Megado, as the treadle is depressed, the rising
shafts move, and as they rise, the back part of the loom also rises. This action automatically
creates a shed of raised and lowered threads that is progressively greater toward the back
and therefore completely even at the front in addition to equalizing tension on all warp
threads.
The first drawing below shows the Megado at rest. The second shows the
progressive shed
achieved during treadling
Megado treadling is very light
When a shed is formed on most looms, the activated warp threads move through a greater
distance than they do at rest. This means that the activated warp threads are under greater
tension, and they become stretched. If the warp is of an inelastic material and held at high
tension, the force required to treadle can be considerable. With the Louët Spring and Delta
countermarch looms, this problem is overcome to some degree: The breast beam moves
during treadling to decrease the distance between front and back beams, therefore
decreasing the distance the through which the activated threads move. With the Megado, the
problem is completely overcome: Not only does the back part of the loom move up, but the
back beam also moves a little towards the breast beam during treadling. This causes
activated warp tension to decrease from even its resting tension—actually helping you make
the shed!
