Device for forming a composite laminate for obtaining a Z-shaped profile, the Z-shaped profile comprising a web and a first and a second flange located at both ends of the web, the device comprising: - a grip module comprising two plates, the grip module configured to enclose and grip between the two plates a first portion of the composite laminate to be formed corresponding to the area of the laminate that will form the first flange, - a feed module comprising two plates, the feed module configured to enclose between the two plates a second portion of the composite laminate different from the first portion located in the grip module, the feed module configured to heat the portion of the composite laminate located between its two plates and configured to be movable with respect to the grip module in a direction parallel to the plane of the web of the composite profile once formed, between: - a first position in which the two plates enclose the portion of the composite laminate corresponding to the area of the composite laminate that will form the web and the second flange, and - a second position in which the two plates enclose the portion of the composite laminate corresponding to the area of the composite laminate that will form the second flange, such that during the movement between the first and second positions, the portion of the composite laminate corresponding to the web slides out of the two plates of the feed module due to the relative movement between the grip module and the feed module, the device characterised in that it comprises a temperature resistant release film located over the surfaces of the plates of the feed module configured to be in contact with the composite laminate to reduce the friction coefficient between the plate and the composite laminate. - a grip module comprising two plates, the grip module configured to enclose and grip between the two plates a first portion of the composite laminate to be formed corresponding to the area of the laminate that will form the first flange, - a feed module comprising two plates, the feed module configured to enclose between the two plates a second portion of the composite laminate different from the first portion located in the grip module, - a first position in which the two plates enclose the portion of the composite laminate corresponding to the area of the composite laminate that will form the web and the second flange, and - a second position in which the two plates enclose the portion of the composite laminate corresponding to the area of the composite laminate that will form the second flange, such that during the movement between the first and second positions, the portion of the composite laminate corresponding to the web slides out of the two plates of the feed module due to the relative movement between the grip module and the feed module, the device characterised in that it comprises a temperature resistant release film located over the surfaces of the plates of the feed module configured to be in contact with the composite laminate to reduce the friction coefficient between the plate and the composite laminate. such that during the movement between the first and second positions, the portion of the composite laminate corresponding to the web slides out of the two plates of the feed module due to the relative movement between the grip module and the feed module, the device characterised in that it comprises a temperature resistant release film located over the surfaces of the plates of the feed module configured to be in contact with the composite laminate to reduce the friction coefficient between the plate and the composite laminate.
