Abstract

See full text

A method and apparatus for the attachment of file fastener to a backboard is disclosed. Backboard, usually pressboard is resistant to attachment by hot melt glue. This problem is overcome by providing deflector for increasing the heat retention angled to provide a chimney effect, pressing the fastener at its tangs toward the heating element, and providing an elastic anvil and hammer which distribute force over a longer period of time.
