Abstract
Staple depressions formed in a panel by the operation of a pneumatic staple driver are automatically filled with putty from a disposable cartridge. Delivery of the putty from the cartridge is automatically sequenced by the operation of the staple driver trigger. Actuation and release of the staple driver trigger causes a measured quantity of putty to be forced into a putty delivery port. The putty is then pressed into the staple depression.
