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 ( ) has a coil spring portion ( ) provided on one of its ends and a band passing ring portion ( ) provided on the other end is mounted on one of ends of the reel shaft ( ). One of ends on the coil spring ( ) side in the brake arm ( ) is fastened to a fixed member such as a device frame. The diameter of the coil spring portion ( ) is reduced to cause the inner peripheral surface of the coil spring portion ( ) to closely engage the outer peripheral surface of the reel shaft ( ), thereby stopping rotation of the reel shaft by frictional force, when the force for feeding the band is released.
