1. A roll-packing machine for packaging a mattress, the roll-packing machine comprising:
a belt drive mechanism comprising a closed-loop belt;
a feed mechanism configured to feed the mattress to the belt;
a tiltable support structure independent of the feed mechanism,
wherein the belt drive mechanism is configured to form an inner loop of the belt, to receive the mattress in the inner loop, and to roll the mattress by advancing the belt while the mattress is received in the inner loop,
wherein the belt drive mechanism comprises a first roller and a second roller, the inner loop being formed between the first roller and the second roller,
wherein the belt drive mechanism is configured to adjust a size of the inner loop by individually controlling rotation of the first roller and the second roller, and
wherein the first and second rollers may be separated by tilting the tiltable support structure, resulting in the inner loop being opened, so that a mattress roll formed in the inner loop is released and removed by rolling along the belt above the tiltable support structure.
