Abstract
Four pairs of paper drive rollers are provided which may be individually adjusted so that proper balancing of the bite pressures result. The same springs employed for this purpose are also utilized to maintain the mechanism locked and to provide rapid and easy opening of the mechanism to widely separate the rollers for the purpose of cleaning and preventing the rollers from being flattened due to continued application of bite pressure when the machine is not being used.
