ABSTRACT:
Sheet feeding apparatus for use in a sheet thickness monitoring system comprises a pair of rollers (1, 5) which define a nip or gap (25) therebetween, the rotation of the rollers (1, 5) causing sheets to be fed between the rollers. The passage of a sheet between the rollers (1, 5) causes deflection of one roller (5) relative to the other (1) by an amount related to the sheet thickness. The one roller (5) is biassed into engagement with the other roller (1). The apparatus further comprises elastomeric plugs (13, 14) for damping movement of the one roller (5) under the influence of the bias.
