摘要： In a thread supply device used in a sewing apparatus having a plurality of needles and a looper mechanism, needle threads guided to the needles and a looper thread guided to the looper are cut by a thread cutting unit at a cutting position, which is off a thread supply path, after a sewing operation is finished but before the following sewing operation starts. The thread supply device comprises a supply mechanism, a stopping mechanism, a memory and a control unit. The supply mechanism forcibly supplies the needle threads and the looper thread. The stopping mechanism stops the threads from being supplied. The memory stores an extra length of each thread, which is required for a cutting operation. The control unit reads out the extra length from the memory and controls the supply mechanism and the stopping mechanism so that each thread is supplied in the extra length.

摘要： A needle thread feed regulating device utilized in high speed overedge sewing machines which form safety stitches composed of overedge stitches and double chain stiches. The needle thread feed regulating device comprises a thread guide mounted on the sewing machine frame and an oscillating thread guide which moves in cooperation with the sewing machine main shaft. The oscillating thread guide has a cam plate which regulates the feed of both the thread for overedge stitches and the thread for double chain stitches.

摘要： An automatic thread supply device for a conventional overlocking sewing machine is disclosed. Each of a needle thread, an upper looper thread and a lower looper thread is supplied to a thread supply roller but the supply is stopped for an optimum period by a thread holder, whereby the supply length of each thread is adjusted. In forming a thread chain, the total supply length of the looper threads is not more than five times of the length of the needle thread, and the smallest length of the above threads is not ore than half of the total length of the remaining threads. In this way, a highly expandable thread chain is formed having a good appearance.
