ABSTRACT:
Only one of the two bobbins located side by side is wound at a time. When one bobbin is full, a thread guide must switch the thread to the adjacent empty bobbin. In order to keep the thread wound up on the full bobbin from unwinding, it is held by a pressure applying element such as a brush, against the immediately adjacent bobbin flanges until the loop between the bobbins is cut by a cutter.
