ABSTRACT:
In a hot-melt adhesive system, a glue stick is provided with a transverse cross section which is acircular. A glue gun is provided with an acircular opening in the gripper housing and an acircular opening in the heating element to accommodate a glue stick. In a preferred embodiment, the major dimension of the glue stick is approximately one-half inch while the smaller dimension is slightly more than one-quarter inch. The acircular glue stick provides excellent heat transfer in the heating chamber and permits a simpler manufacturing process. The gripper housing includes a gripper element which engages a major part of the width of the glue stick and can transmit a large advancing force without becoming embedded in the stick.
