PROBLEM TO BE SOLVED: To provide conveyance equipment which softens a blank for forming by heating without contact with a conveyance member while conveying and controls the temperature thereof to a state suitable for forming with a simple structure, a conveyance method and press forming equipment. SOLUTION: A nozzle member 53 is maintained in the state that a discharge port 53b exists upward in a perpendicular direction from the opening end of a recessed part 53a and when the gaseous nitrogen blown off from the discharge port 53b passes the spacing between a preform PF and the inner wall surface of the recessed part 53a, the pressure of the gas drops according to the velocity of flow thereof and a pressure difference occurs between this spacing and an opening end side, by which the preform PF is floated and held in a contactless state and therefore the wear of the nozzle member 53 having the possibility of occurring in case of contact with the preform PF and the fusion welding of the material to be conveyed and the nozzle member can be averted and even more the upper part of the preform PF is covered by the recessed part 53a and consequently the possibility of the adhesion of foreign matters, such as dust, during conveyance is low. Since the hand-over of the preform PF without inverting the recessed part 53a as in the prior art is possible and therefore the constitution is simplified and the instability in the hand-over can be eliminated.
