Abstract
An apparatus for facilitating handling particularly tab stock in a sheet feeder, having a top feed vacuum corrugated feed head assembly for feeding sheets seriatim from a sheet supply stack. The facilitating apparatus includes a platform adapted to support a sheet supply stack of the tab stock type. A tab stock sheet supply stack is located on the platform in relation to the top feed vacuum corrugated feed head assembly. A force is applied to the tab stock sheet supply stack, such force having at least a component in a direction relative to such tab stock sheet supply stack to prevent individual tab stock sheets in such stack from prematurely moving out of control of the top feed vacuum corrugated feed head assembly.
