Abstract

A system for the continuous deposition of a semiconductor material onto one or more webs of substrate material which are advanced therethrough includes a web transport system having a plurality of web support assemblies. Each web support assembly includes a base having a primary support arm pivotally mounted thereto so as to be displaceable from a first position to a second position. The support includes a first biasing member in mechanical communication with the primary support arm. The first biasing member operates to impart a first biasing force to the primary support arm so as to move it from its first position to its second position. The support includes a dancer arm which is pivotally mounted to the primary support arm so as to be displaceable from a first position to a second position relative to the primary support arm. The system further includes a second biasing member in mechanical communication with the dancer arm. The second biasing member operates to impart a second biasing force to the dancer arm so as to move it from its first position to its second position. A roller is rotatably supported on the dancer arm. The roller is configured to engage a portion of the web. The web support assembly operates to maintain continuous contact between the roller and the moving web of substrate material as it passes through the deposition system.
