Abstract

PURPOSE: To deliver a thread without being affected by the mass of a thread drum by horizontally arranging the thread drum, putting the entire thread in a cassette and providing an imparting and adjusting mechanism of thread tension on the cassette. CONSTITUTION: The cassette 50 is provided with a hole 50a slightly larger than the outer diameter of the thread 51 on a center part and a slit 50b and a T-shaped hole 50c for inserting the end part 51a of the thread 51, the thread 51 is housed in the hole 50a and the end part 51a is passed through the slit 50b and the hole 50c and discharged to the outer side of the cassette 100. Then, an almost L-shaped leaf spring 52 is provided with a projection on one end part, it is engaged with one of plural notches 50d provided on one side face of a cassette body and the other end clamps the end part 51a of the thread with a pin 53 and imparts tension. Thus, in the case that the kind of the thread or the thickness of the thread is changed, by changing the engaging position of the notch 50d and the projection of the leaf spring, the clamping pressure of the pin 53 and the leaf spring 52 is changed and the tension is adjusted.
