ABSTRACT:
A bag neck tying device for tying a ribbon about gathered material. The bag neck tying device includes a bag gathering mechanism for moving a bag neck into engagement with a bag stop lever controlled by an electric brake. The bag neck tying device further includes a needle assembly for wrapping the ribbon around the gathered neck of the bag, a twister hook assembly for twisting the ribbon of tie material and a ribbon holder-shear assembly for cutting and holding the end of the ribbon. The gathering, needle, twister and holder-shear assemblies are controlled by bi-directional, brush type DC servomotors driven by full wave rectified solid state DC motor controllers in a closed loop control system which incorporates a software driven microcontroller for delivering reference input signals to the motor controllers for initiating and controlling pre-assigned functions of the motors driving the various tier assemblies.
