A method and apparatus for continuous casting of metal strip, the apparatus having (i) a first endless belt supported and moved on the surfaces of a first entry pulley and a first exit pulley and (ii) a second endless belt supported and moved on the surfaces of a second entry pulley and a second exit pulley, with an entry nip defined between the first and second entry pulleys and an exit nip defined between the first and second exit pulleys. Opposing surfaces of the first and second belts progressively diverge from each other in the direction of movement thereof. The apparatus may include a cooled roll in place of the first pulley and first belt with a nip defined between the cooled roll and the second entry pulley.
