ものがあった。[Prior Art] Conventionally, this type of sewing machine has a pair of needles arranged at intervals along an axis perpendicular to the cloth feeding direction, which performs a needle feeding movement to transport the work cloth in cooperation with a feed dog. needle and
(A pair of thread ring catchers are arranged on both outer sides of the pair of needles and are rotated clockwise around one vertical axis when viewed from above on the cloth feeding side, and a one F thread carried on the needles. and a pair of thread cutting blades that can reciprocate simultaneously to cut the bobbin thread stored in the thread loop catcher, and the pair of thread cutting blades.
Some were equipped with a drive device that reciprocated the ``''.

ずかしい欠点があった。Here, thread trimming is done just before the sewing machine stops, so
The left and right thread trimming blades 9 must reciprocate at high speed in a short period of time to trim the thread, which may result in thread breakage or idling of the bobbin, and it is difficult to adjust the mechanism for reciprocating the thread trimming blades at high speed. There were drawbacks.
