Abstract
Head for the automatic positioning of fiber blankets, which determines a path for the fiber blanket (2) to be positioned, as far as a positioning zone (5), passing via a resin-impregnation zone (4) and via a cutting zone (3), including, in front of and behind said zones (3 and 4) individual sets of rollers (6-7) that convey the fiber blanket (2) and control the tension thereof.
Claims8
A head for the automatic positioning of fibre blankets, comprising:
- an impregnation zone (4) in which the fibre blanket (2) to be positioned is impregnated with a resin and a catalyst necessary for the application thereof;
- a positioning zone (5) for positioning the fibre blanket (2) on a corresponding surface of a mould or mandrel;
- a cutting zone (3) which allows cutting the fibre blanket (2);
- upper and lower sets of driving and pressure rollers (A and B) that convey the fibre blanket (2) and maintain a suitable tension thereof at different points of a path for the fibre blanket, from feeding thereof into the head to the positioning zone (5);
- and
- elements for immobilizing the fibre blanket (2) arranged in front of and behind a cutting tool (10), which elements are formed by hold-down plates (12) coupled to pushing cylinders (13) which press the fibre blanket (2) against a corresponding fixed structure (14), immobilizing the fibre blanket to perform the cutting, said hold-down plates (12) occupying an advance position when the cutting tool (10) is operating and a retreat position when the cutting tool is at rest.
