A method and apparatus for applying glue to boxes, and more particularly a method and apparatus that is used for applying glue to boxes during a process of sealing the flaps of boxes is disclosed. A suitable position feedback device is an electromechanical device comprising an encoder ( or aC??resolveraC?? ) 78. As shown in fig. 1, the encoder 78 is driven by the belt 12 and pulley 18B that is opposite the pulley 18A which is being driven by the drive 14 of the box-making machine 10. In other embodiments, the encoder 78 can be located in any other suitable location and driven by any other component, such as other components of the box-making machine 10. The encoder 78 (or other carton position-indicating divice) is in electrical or electronic communication with the servomotor 74 such as through a wire, or otherwise. |
