I do not get “The cam is used to release the energy stored in elastic bands”. Some people try to make every part with a 3D printer just because they have a 3D printer, but this build has a quite reasonable combination of aluminium and steel axles, acrylic side panels and 3D printed small parts. One reason I like this build is because of the combination of techniques. Things like sowing timing belts together and trying to use timing belts on V-groove pulley’s clearly shows the start of a learning curve in this area. I do sort of like the reproduction of this thing and having the perseverance of making it work, despite the inexperience of the builder with basic mechanical stuff. Posted in Misc Hacks Tagged loom, shuttle, warp, weaving, weft Post navigationįor today’s standards, this type of loom is a pretty simple device, and I find it a tad sad that hackaday tries to overly exaggerate the complexity of this thing. Hats off to for showing the true complexity involved in automating weaving. We’ve seen power looms before, but mainly those that operate at a somewhat more stately pace than this one. had to play with cam shape and lever arm length to get the timing right, not to mention having to resort to a chain drive to get enough torque to move the shuttle. Shuttle timing is critical, as a few of the fails later in the video show. The mechanism that moves the shuttle back and forth in the shed is particularly interesting it uses cams to release the tension stored in elastic bands to flick the shuttle left and right. There are levers, shafts, and cams galore, not to mention the gears and sprockets that drive the mechanism via a 12-volt gear motor. ’ version of the flying-shuttle loom is built mostly from 3D-printed parts, with a smattering of aluminum and acrylic. The weft thread is then pressed in place by a comb-like device called the reed, the heddles carrying the warp threads shift position, and the process is repeated. The main idea with weaving is to raise alternate warp threads, which run with the length of the fabric, to create a virtual space, called the shed, through which a shuttle carrying the weft thread is passed. And judging by how much work went into this miniature 3D-printed power loom, not to mention how fussy it is, it’s a wonder that we’re not all still wearing homespun cloth.ĭealing with the warp and the weft of it all isn’t easy, as discovered with this build. The seemingly humble flying-shuttle loom, originally built to make the weaving of wide cloth faster and easier, stood at the threshold between the largely handcrafted world of the past and the automated world that followed.
