ABSTRACT:
An adjustable diameter roller useful for feeding and scoring or creasing paper and for other applications. The roller has a ring-like elastic tire coaxially surrounding a hub between coaxial circumferential shoulders on the hub having confronting annular shoulder faces which are tapered to diverge radially outwardly of the hub and abut similarly tapered side faces on the tire, and means for effective relative axial adjustment of the shoulders toward and away from one another to effect radial expansion and contraction of the tire and thereby adjust its outer diameter.
