Purpose of the development: For simplification of process of formation of stitch, increase of his durability and elasticity.

Recommended application field: Light industry, namely to the methods of formation of chain stitches.

Technical characteristic: A method includes the use of two needles, two needle filaments, interlacing, which appears from lower part of material, one petel\'nika which is revolved. The entrance of needles is carried out athwart the surface of material.

Advantages over analogues: Simplicity of construction of sewing machine, high elasticity of interlacing and firmness, is to not blooming.

The development stage readiness: Introduced in production

Technical and economic effect: Simplification of construction predetermines economic efficiency in its making and exploitation.

Description of the development:
()
A task will be realized due to that: dvonitkoviy a chain stitch appears groups from four simple chain stitches, thus pricking of material takes a place two needles simultaneously, and displacement of stitch to the left (to the right) in relation to lines takes a place due to the increase of natyagu of one of filaments.
