Patent ID: 8453831

Claim:
A roller for a conveyor system, a) the roller including: 1) an inner core assembly rotatable about an inner core central axis, the inner core assembly having an inner core thickness; 2) a porous rigid expanded foam roller body circumferentially surrounding the outer surface of the inner core assembly; 3) an outer layer circumferentially provided about at least a portion of the outer surface of the foam roller body, the outer layer being made of a different material than the foam roller body; and 4) a rigid torque coupler extending radially outwardly a coupler distance from the inner core central axis, wherein: (i) the torque coupler is at least partially embedded within the foam roller body; and (ii) the coupler distance is at least half as great as the inner core thickness; b) whereby when the inner core assembly is rotated about the inner core central axis in a driven conveyor system, the torque coupler transmits torque experienced by the inner core assembly to the foam roller body such that the foam roller body rotates with the inner core assembly.
