A vacuum transport includes a segmented, rigid or solid articulated belt combined with a vacuum plenum in each segment of the belt. The heat transfer device is coined as the reciprocating-mechanism driven heat loop which comprises a hollow loop having an interior flow passage, an amount of heat-carrying fluid filled within the loop, and at least one reciprocating driver. As one spring assembly increases pressure, the other spring assembly produces pressure to maintain uniform tension on the line holding release clip.
