A material application system for applying a panel of material to a framework with a shoe for retaining the framework, a nest, opposed mechanisms for retaining opposite portions of the panel of material traversing between the shoe and the nest, an arrangement for selectively moving the shoe and the nest into and out of an engaged position wherein the panel of material is sandwiched between the shoe and the nest and a disengaged position, and an arrangement for inducing an attachment of the panel of material to the framework. The opposed mechanisms can be clamping mechanisms, which can be segmented and individually moveable to enable variable pretensioning. A contoured deflection control member can alternatively produce variable pretensioning. A pressing arrangement with a tooth member can press a locking spline into a groove in the framework to secure the material. |
