Abstract
A stretching machine (101) for stretching a variety of sizes of plastic sheet (103). A clamping assembly (105, 107) is connected to a primary clamp (111) of an orthogonal clamping assembly (105, 107), the connection being removable to allow connection to a different primary clamp (111) so as to accommodate a different size of plastic sheet (103). The number of primary clamps (111), each of which provide a discrete clamping, can also thereby be tailored for a particular stretching process. Stretching and forming apparatuses employing such clamping assemblies (105, 107), as well as a method of configuring such machines, are disclosed, each of which provide for increased flexibility.
