Compensating pressure roller

摘要

A pressure roller assembly for use in a transport system. The transport system including a drive system in operative engagement with the pressure roller assembly for feeding an article in a path of travel. The pressure roller assembly including: a shaft; a roller having an inner diameter; a pair of first hubs each having a bearing surface and fixably mounted to the shaft in spaced apart relationship so that the first hub bearing surfaces are facing each other; a pair of second hubs each including an through hole having a diameter greater that the shaft diameter and a bearing surface corresponding to the first hub bearing surfaces, respectively, the second hubs spaced along the shaft between the first hubs and slideably mounted to and in bearing engagement with the roller inner diameter so that the second hub bearing surfaces are facing the first hub bearing surfaces, respectively; and means for biasing the second hub bearing surfaces into bearing engagement with the first hub bearing surfaces, respectively.
