Method and apparatus for dispensing material onto substrates

摘要

A method and apparatus (10) for dispensing material, including adhesives, onto a substrate, including boxes and cartoons. A first and second dispenser (12,14) are either operated in a dispense and standby mode or both dispense at least a portion of the dispensed pattern. The detection of a failure of one of the dispensing guns (12,14) causes the other gun to dispense the complete pattern while de-activating the failed gun thereby maintaining production. <IMAGE>
