Abstract: A band refeeding method in a banding packing machine is disclosed which can prevent the tip portion of a band from being excessively pulled back even if the band is not supplied correctly but is automatically pulled back, and can stay the band in a predetermined position and can successively supply the band to the band guide arch side. A length of a band to be pulled back to an original position by band pull back means is previously detected based on the number of rotations of a touch roller constituting band supply means. In addition, the number of rotations of the touch roller before reaching a predetected set value is detected when the tip portion of the band is pulled back. Then, a rotating speed of a roller of the band pull back means is reduced when the number of rotations is detected. Therefore, the roller of the band pull back means is subsequently rotated at the low speed, thereby pulling back the tip of the band to a predetermined position.

Abstract: Sound and power are an important part of the motorcycling experience. From the early days people have been attempting to get it “right” and have tried numerous ways to achieve the best of both worlds. Generally one had to be sacrificed to some degree to get the other. Tuning the exhaust rather than tuning the carburetor or increasing cubic inches is a less expensive and more efficient way to get both the sound and midrange power that motorcyclists are looking for. With the Exhaust Enhancement exhaust pipes can be tuned for sound and increased midrange power very simply and easily by installing them in the exit end of an aftermarket straight type pipe using various combinations to achieve a desired sound and not sacrifice power.
