Abstract

A headbox structure for feeding a slurry of stock onto a traveling forming surface for a paper making machine including a tapering slice chamber with a slice opening and trailing elements positioned in the slice chamber extending in a downstream direction with the elements being unattached at their downstream edges and being self-positionable responsive to pressures of stock flowing past the element with the edges of the elements adjacent the pond sides being extended for obtaining a more uniform stock delivery and basis weight of paper web.
