Abstract

Membrane manipulating and compacting device for obtaining preforms useful in the automated manufacture of composites, comprising a support structure (1) with a central opening (1.3,1.4), coupleable to a moveable translation element; an elastic membrane (4) covering the central opening (1.3,1.4), and it comprises a smooth upper layer (5) impermeable to air and a lower layer (6) permeable to air provided on its upper face with projections (7) allowing a distribution of a vacuum applied by means of a vacuum connector (9) which opens between said layers (5,6) for suctioning air through the lower layer (6) and between the projections (7), for retaining a fiber fabric sheet (13) in the lower layer (6) by the action of the vacuum; these layers (5,6) being hermetically joined at their peripheries and made of an elastically flexible material such that when they are overlain on a preforming mold (3), an air-tight area is produced in the molding area and a vacuum and/or pressure is applied, and they deform adopting the geometry of the mold (3).
