Zusammenfassung:	The invention relates to a process for manufacturing a textile preform from a fibrous array with continuous fibres, the process comprising a step for heating of the fibrous array between a matrix and a punch to stiffen this fibrous array. To cut down processing time, the heating step is performed by having a hot gas flow circulate through the matrix, the fibrous array and the punch.
