Back Beam and Warp Beam
Removal for Warping

If the loom is being warped Front-To-Back, the Back Beam and Warp Beam of the Leclerc larger floor looms can be removed during the warping process to allow the weaver to sit inside the loom frame to make it easier to thread the heddles.

This process applies to most Fanny, Mira, Nilus, Nilus II, Nilart, Colonial and Weavebird models although the design of some very early models may prevent part of this disassembly. This also shows the removal of the standard lower Beater while the assembly instructions for the Colonial/Weavebird Hanging Beater should be consulted to remove them. The loom in the pictures is a Nilus II with Front Hinge Treadles so the configuration may be slightly different depending on the model.


Step 1 - Remove Back Beam

The first step is to remove the Back Beam. This wooden bar lifts off the two metal pins on either side without using any tools. After lifting one end off the pin, moving that end of the beam horizontally toward the weaver may make it easier to remove the other, but be careful to only move the end an inch or two horizontally as it is very easy to crack the wood on the other post because of the leverage provided by the length of the Back Beam. Just lift the other end straight up to remove the beam.


Step 2 - Disconnect the Brake Circle

The metal Brake Circle wrapped around the Brake Drum on the end of the Warp Beam needs to be released from the pressure the spring is applying on it. On newer looms ( 1979 and later) that have a turnbuckle as part of the brake, one end of the turnbuckle can usually be disconnected by simply pulling up on the brake lever which stretches the spring. In some cases the turnbuckle body must be rotated first to lengthen it. On very new looms the turnbuckle will be permanently attached to the brake lever so the brake circle should be unhooked from the top end of the turnbuckle. Once the brake circle is unhooked it will expand making it easier to pull the beam out. Do not bend or distort the shape of the brake circle.

Disconnecting the Brake Circle will allow the Warp Beam to rotate unwinding the Apron and Warp rods so we suggest tying a string around the apron at both ends of the beam before releasing the brake. See below for older looms with the earlier brake system.


On older looms (1960-1970's) with a old style brake lever and brake cord, the spring must be grasped directly and pulled up to stretch it. The brake circle can then be removed from the end of the brake spring s-hook and then the s-hook can be disconnected from the brake lever. Note that the long end of the brake lever points toward the back of the loom when later reconnecting the brake lever and brake spring.


Step 3 - Unlatch Left Side of the Warp Beam

The ends of the Warp Beam fit in slots in the wooden loom frame and is held in place with metal latches on either side. By loosening the wingnut, this latch can be folded out of the way. Be careful to support the warp beam with one hand, undo the wingnut on the latch on the back left side of the loom (opposite end from the brake drum). Once the latch has been flipped out of the way, the warp beam end can be removed out from the slot a few inches and by moving the warp beam toward the left side of the loom, the end on the right side can be pulled out of its slot and out of the brake circle. The beam can then be set on the floor.

Note that on very early versions of the F-Type (Fanny), M-Type (Mira) and Nilus looms, the cloth beam may go through holes in the frame instead of sitting in slots. On these looms, the Warp Beam cannot be removed without partially disassembling the frame.


Step 4 - Remove the Cloth Beam and Warp the Loom

With the Latches on both sides opened and the Frame Pawls out of the way, the Cloth Beam can be lifted out of the frame and then placed out of the way. The Take-Up Motion handle can stay attached to the right side of the Cloth Beam. At this point the weaver can place their chair in the loom and sit between the treadles to access the reed. Note that normally the Treadle Pins are removed to allow the treadles to lower onto the frame so the weaver can rest their feet on them while they work. On the Back-Hinge Treadle looms, the Rocker Cords can also be disconnected to allow the Treadles to lower.

With the Beams and the Beam and Warp Beam removed the Shaft Frames and Heddles are now more accessible to the weaver and a chair can be placed inside the loom. When done, the Warp Beam can be reinstalled by just reversing this process.
