Abstract (en)
[origin: EP3763865A1] The bobbin thread introduction device of the present invention is mounted in the sewing machine and comprises: two motion modules, a clamp module and two moving modules. One of motion modules is provided with a blade, and can drive the bobbin to wind the bobbin thread. The clamp module at the clamping position can clamp bobbin thread, and can move back and forth on two different paths through two moving modules, so that the clamp module holds the bobbin thread to touch the blade. Wherein, the other motion module rotates when the bobbin thread contacts the bobbin case, which makes the rotating bobbin case guides the bobbin thread into the thread guiding slot of the bobbin case. By doing so, the two motion modules, the clamp module and the two moving modules can not only jointly wind the bobbin thread around the bobbin, but also introduce the bobbin thread.
