Abstract (en)
[origin: WO9930837A1] The present invention relates to a glue gun (10) for selectively supply molten adhesive. The glue gun comprises a housing (12), an actuator (16) movable between actuated and non-actuated positions, and a nozzle (18) configured to allow molten adhesive to flow therethrough. The housing includes an adhesive receiving chamber (27) fluidly communicating with the nozzle. The chamber (27) has an opening at one end thereof for allowing a supply of solidified adhesive to be inserted into said chamber. A heating element is associated with the chamber. The heating element (80) is operable to apply heat to the lead end portion of the solidified adhesive supply sufficient to melt the lead end portion when an electric signal is applied to the heating element. A heating element controller operates to allow the electric signal to flow to the heating element for a period of time after the actuator has been moved to its non-actuated position and to thereafter prevent the electric signal from flowing through the heating element at the end of the time period. The present invention also relates to a timing circuit for controlling the amount of time during which an electric signal is supplied to an operative element.
