The HM830 triple transport binding machine is based on a completely new design. This model is unique because the differential binder mechanism does not fill the right-hook area. This allows us to build the HM830 with the hook on the right side of the needle. This tackles and solves all the disadvantages of the more conventional left-hook models. The benefits of this design includes low-tension sewing, and better overall seam quality due to the natural kinematics of the machine. You no longer need an S-twisted top thread.
