Cyclostyle \Cy"clo*style\ (s?"kl?-st?l), n. [Cyclo + style.]
   A contrivance for producing manifold copies of writing or
   drawing. The writing or drawing is done with a style carrying
   a small wheel at the end which makes minute punctures in the
   paper, thus converting it into a stencil. Copies are
   transferred with an inked roller.
