Abstract
A two-component resin or adhesive dispensing system including an air drive motor with adjustable settings which drives, by means of sprocket and chain drive systems, an activator metering pump and an adhesive metering pump as to provide a dispenser with adjustable amounts of activator material and adhesive material. The metering pumps are mounted upon adjustably movable mounting brackets such that their relative disposition may be readily altered so as to accommodate different sized sprocket members which will then alter the drive output of the metering pumps in order to change the ratio of activator material dispensed with respect to the amount of resin or adhesive material dispensed.
