Abstract

A dispenser for sequentially dispensing one sheet at a time from a stack of sheets. A housing encloses a drive and a lift roller, and each roller has a longitudinal axis arranged in parallel aligned relationship respective to one another and spaced from the one another an amount to bring the outer peripheral surfaces thereof into rolling contact with one another. A holding post is aligned in parallel relationship with respect to the rollers and is spaced therefrom for enabling a stack of sheets to be held against the holding post and lift roller, with one outermost sheet having a marginal edge portion thereof urged against the lift roller and the opposed marginal edge portion thereof is urged against the holding post. The outer peripheral surface of the drive roller is made of high friction material while the lift roller has a relatively small segment of its outer peripheral surface made of high friction material and the remainder of the peripheral surface made of low friction material. The low friction material has a co-efficient of friction which is less than the surface of the sheet while the high friction material is greater than the co-efficient of friction of the surface of the sheet. The drive and lift rollers engage one marginal end of the outermost sheet which is lifted by the roller and thereafter transferred by the lift roller to a location between the drive and lift rollers which jointly engage and transport the sheet to an opposed side of the rollers to a station while concurrently pulling the sheet from between the stack and post.
