An apparatus for forming a fiber-bundle-based preform from a preform precursor material includes a process head coupled to a robotic arm. The process head has at least two rollers, a heated region, and a cooled region. A length of preform precursor material is passed through the rollers and fixed at a first end thereof. The process head moves relative to the preform precursor material, following a path defined by the movement of the robotic head. The path comports with the desired shape of the fiber-bundle-based preform. As the process head moves, it softens a portion of the preform precursor material, which then passes through the two rollers, the combination thereof incrementally altering the shape of preform precursor material to that of the preform. After passing the rollers, the newly formed region of preform is cooled to set its shape. The process head continues to move relative to the preform precursor material until the preform is fully formed.

A molding apparatus for manufacturing a wind turbine blade component includes a main mold body (30) and a flexible bladder (38). The main mold body includes a shape defining surface (32) for receiving composite material forming the blade component and a heat reservoir (40) for heating the blade component during curing. The flexible bladder overlays and conforms to the shape of the blade component and is configured to receive heated liquid for heating the blade component during curing. One or both of the main mold body and the flexible bladder is divided into a plurality of zones (58, 66) that are independently controlled by a controller (70) to maintain a generally uniform temperature of the blade component at each zone.

An air activating and air cooling mold device utilized to process a workpiece includes a mold and an intake device. The mold has at least one gas channel disposed therein, and each of the at least one gas channel has an inlet and at least one outlet. The inlet is disposed on an outer surface of the mold. The at least one outlet is disposed on the outer surface of the mold, is spaced apart from the inlet, and communicates with the inlet. The workpiece is disposed on the mold and covers the at least one outlet. The intake device is mounted to the inlet of the at least one gas channel of the mold, such that gas is injected into the mold via the inlet and flows out of the mold via the at least one outlet.

A female mould having a forming cavity inside which a concave object can be formed, comprises: an annular forming element extending about an axis and delimiting the forming cavity about said axis; a plate element which delimits the forming cavity transversely to said axis, the plate element having a reference surface extending transversely to said axis externally of the forming cavity; a peripheral annular component at least partially surrounding the annular forming element.
