DEFINITION

Classification: 156/406.6

Stretching means:

(under subclass 406.4) Subject matter in which the shaping means applies tension to the material to elongate it.

(1) Note. A means for merely tensioning a web fed to the assembly means does not determine a patent for this subclass unless there is a positive recitation that the web is stretched.

(2) Note. Where the assembly means itself, e.g., a tire-building drum, etc.., is part of the combination of elements which performs the only stretching; the stretching means is not considered "upstream".
