Title: Brake structure of band reel in packing machine

Abstract: A brake structure of a band reel in a packing machine in which reliable braking effects can be obtained and responsiveness can be enhanced. A brake arm (15) has a coil spring portion (16) provided on one of its ends and a band passing ring portion (18) provided on the other end is mounted on one of ends of the reel shaft (13). One of ends on the coil spring (16) side in the brake arm (13) is fastened to a fixed member such as a device frame. The diameter of the coil spring portion (16) is reduced to cause the inner peripheral surface of the coil spring portion (16) to closely engage the outer peripheral surface of the reel shaft (13), thereby stopping rotation of the reel shaft by frictional force, when the force for feeding the band is released.
