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.

A band feed length adjusting device in a packing machine which can newly input, to a control section, a length obtained by manually leading out a band to adjust the feed length of the band and can subsequently feed the band having a correct length in the case in which the size of an object to be packed is changed to be larger.

A touch roller can be moved between three positions. In the first position, the touch roller is pressed onto a forward driving roller. In the second position, the touch roller is pressed onto a reverse driving roller with two different forces. In the third position, the touch roller is spaced from both the forward driving roller and the reverse driving roller. When the touch roller is pushed onto the reverse driving roller with a small force, the reverse driving roller pulls back a band and wraps the band around an article to be packed. When the touch roller is pushed onto the reverse driving roller with a large force, the reverse driving roller tightens the band wrapped around an article.

Band-applying apparatus and method for use in packing system

It is an object to provide a banding packing machine capable of easily processing a right presser member, a left presser member and a middle presser member, reducing the number of parts and readily carrying out attachment with high precision. A drum portion of at least a middle presser member ( ) provided in a central part in a right presser member ( ), a left presser member ( ) and the middle presser member ( ) has a sectional shape of an almost track including a pair of circular arc portions ( ) opposed to each other and a pair of straight portions ( ) opposed to each other, and one of ends of each of drum portions ( ) in the right presser member ( ) and the left presser member ( ) which are opposed to the straight portions ( ) of the middle presser member ( ) is formed rectilinearly.
