ABSTRACT:
A method and apparatus for automated dispensing of liquid materials onto a workpiece. The automated dispensing apparatus has a nozzle assembly which includes a flexible tube that is surrounded by a coil spring. The apparatus may be programmed to slide the nozzle assembly along a surface of a workpiece as liquid materials are discharged from the tube. The spring prevents kinking of the tube and protects the tube from abrasive damage, and also biases the lower end of the tube toward a position in contact with the workpiece.
