.~ Backing for stencil cutting (e.g, celluloid strip, etc.)
DEFINITION
Classification: 400/544
Backing for stencil cutting (e.g., celluloid strip, etc.):
(under subclass 521) Subject matter wherein significance is attributed to a retaining means that holds a record-medium* card, or to a protecting means that protects the platen* from damage by the impacting type-face* elements while the typewriter is being used for cutting a stencil.
(1) Note. As referred to herein, a "stencil" is a card or sheet having a surface that is normally impervious to the passage of ink* from one surface to the opposite surface. However, when the stencil is impacted by a type-face element, the surface is modified along the line that represents the character* symbol corresponding to the type-face, the modification being such as to permit ink to flow from one surface to the opposite surface. The card or sheet that has had its surface so modified is then usable in a "Mimeograph" printing machine. (The term Mimeograph is a trademark.) The operation of typing on the stencil material is known as "cutting" the stencil.
