Abstract
A strip matter cutting device for sewing machine is provided which is mainly employed in automatically cutting a tape or rubber sewed on the shoulders of a T-shirt. It is arranged such that the whole of a cutting part which comprises a rotary cutting blade and a tape receiving portion integrally formed with a tape pick-up portion, is shifted between a cutting action position closely adjacent to the rear of a needle location of a throat plate secured to the top surface of a sewing machine bed, and a non-action position at which the cutting part is retracted upward to the left of a sewing machine arm over the throat plate, through a rock arm which is driven to rock reciprocally by a rotary cylinder. Employment of this arrangement permits an improvement in work efficiency and a significant reduction in work burden. Even for a wide object to be sewed, it is fed freely for automatic cutting of a sewed tape or rubber, without the tape or rubber losses.
