ABSTRACT:
A sheet feeding apparatus capable of feeding corrugated cardboard sheet without the need for feed rolls which comprises a support for sheet having a feed end and a delivery end. The support further includes feed elements comprising at least one feed element driven at a variable speed and at least one feed element driven at a constant speed. The variable speed feed element transfers the sheet from the feed end to the constant speed feed element. The constant speed feed element transfers the sheet from the variable speed feed element to the delivery end. The variable speed feed element is driven by a variable speed generating mechanism which generates a motion cycle including a constant speed output segment which is equal to the constant speed of the constant speed feed element. The sheet feeding apparatus provides a smooth continuous, controlled transfer of the sheet from the feed end to the delivery end of the apparatus.
