ABSTRACT:
Improvements in securing a blanket in place in vacuum bagging and like operations. Known systems for securing the blanket are cumbersome and time consuming and do not allow sufficient adjustment of the tension on the blanket. The system of the invention allows quick and easy attaching and detaching of the blanket, allows a wide range of adjustment of the tension, and does not require accurate alignment of the blanket. A strip (32) of net material is attached to a blanket (30) around the periphery of the blanket (30). A plurality of horizontally spaced pins (20) are secured to a lay-up structure (2) and positioned to extend downwardly and outwardly. The blanket (30) is placed over the structure (2) with the net (32) hanging down around pins (20). Net (32) is pulled over the free ends (22) of pins (20) to extend free ends (22) through holes (38) formed by the net structure. Tension may be adjusted by extending pins (20) through different holes (38).
