Description

  The present invention relates to a folding machine used mainly for teaching materials and hobbies.

In general, what is called a loom forms a woven fabric by crossing warp and weft, and is distinguished from knitting that links one yarn.
By the way, weaving looms have long supported Japanese key industries, and it is meaningful to understand their mechanism. However, today's looms have been increased in speed to improve their productivity, and there is a problem that it is difficult to fully understand just by looking at the looms that are actually in operation.

  On the other hand, in patchwork of hobbies that make small items by connecting small hagile cloths, you have to search for and collect a small amount of cloth pieces that suit your taste, and it takes a lot of labor to collect it, There was also a problem that it would become uneconomical due to excessive and insufficient.

Therefore, a model in which an old loom is scaled down as it is has been proposed for such problems.
This model is equipped with a warping table (creel) on the upper side of the loom model equipped with heels (wire-held) that move up and down alternately, and the warps supplied from this warping table are alternately opened with scissors, The fabric is woven by driving wefts into each opening.

  However, such a device is equipped with a warping table, so it is effective for weaving a long continuous tape-like cloth. There was a problem that the teaching materials for understanding the mechanism of the cage were wasteful and unsuitable.

Furthermore, there is a problem that a minimum of two reeds are required to open the warp, which is expensive, and the structure is complicated due to the interlocking mechanism that moves the reed up and down.
In addition, there is also a problem that it takes time to pass the warp through the kite and a great deal of time is required before the weaving.
