The Bunn line of rotary tying machines are designed to wrap bundles with string or polytape and tie a knot. Machines are available that wrap twice or three times either one way or cross tie. The machine operator positions the bundle on the front table and presses the foot trip. By means of a revolving arm that carries the string around the bundle it is securely tied automatically. 6 models are available depending on the size of bundle. See the Bundle Size Chart to determine maximum capacity of each machine. Height depends upon exact width. All machines operate on 110 volts.
