    摘要： An automatic dispensing device for wallboard joint taping is provided, including a body for holding a supply of viscous material and having a rear end and an opposite front end, a spool assembly disposed on the body and configured for supporting a spool of tape; at least one drive roller positioned at the front end and receiving an end of the spool of tape. Certain embodiments include an adhesive application assembly connected to the drive roller and mounted in operational relationship to the front end for dispensing a measured amount of adhesive upon an upper surface of the tape upon rotation of the at least one drive roll. In such embodiments, the body may be configured for holding sufficient adhesive to cover tape advanced by at least 200 rotations of the at least one drive roller.
