Abstract
A hand-held operator manipulatable applicator device is used for dispensing adhesive bonding material to bond a panel (such as an automotive glazing panel). The device has a body containing a delivery channel for delivering adhesive to an outlet nozzle and a heating system disposed within the body for heating the bonding material in the channel to produce a substantially uniform outlet dispensing temperatures via the nozzles.
Claims23
A method of securing a panel with an adhesive bonding material, using hand-held operator manipulatable dispensing device to dispense adhesive bonding material via a dispensing outlet of the device, the method comprising subjecting the bonding material to a predetermined temperature regime, the predetermined temperature regime having:
- (i) a period of heating the bonding material at a predetermined level prior to dispensing from the dispensing outlet of the device;
- and
- (ii) a subsequent period of curing in-situ in contact with the glazing panel at a temperature significantly below the heating temperature level in step (i);
- wherein the temperature of the adhesive bonding material dispensed via the dispensing outlet is maintained substantially uniform as adhesive is dispensed about the periphery of the panel.
An applicator device for dispensing adhesive material, the applicator device being hand-held and operator manipulatable and comprising a body portion including a delivery channel for delivery of adhesive bonding material to a dispensing outlet nozzle, the body portion further including an operator actuatable heating arrangement for heating the adhesive bonding material in the channel, internally of the device to a predetermined temperature level to produce a substantially constant outlet dispensing temperature via the nozzle.
