Additional memo from Mr. Gumbinner 8 Stencil Construction

While Speed-O-Print and Gestetner  were  by far our biggest customers others were Rochester Stencils, Canadian Polychrome stencils and several New York City dealers.  While a large percentage of the stencils we coated were blue we also coated green, white and yellow stencils.  We occasionally coated black cushion sheets which were mounted between the stencil and backing sheet.  To completely prevent type filling we would for the premium stencils mount a sheet of pliofilm, rubber hydrochloride made by Goodyear, on top of the stencil.  It was attached with removable glue dots so correction fluid could be applied if an error was made.  We later glued the pliofilm to a folded tab. It could be used for several stencils.  Louis Mestre made a machine to make the tabs.  He had also made a machine to assemble the stencil and backing sheet.  A roll of backing sheet paper and a roll of the stencil tissue were mounted on the machine. A keyhole was punched in the backing sheet and a line of glue was applied.  After the he stencil and backing sheet were cut off, the direction was changed at a right angle and then fed through two multigraphs to print the heading and scale, and then a unit that punched the mounting holes on the backing sheet.  The ink for printing the scale was purchased from IPI.  But I found that if we used paralac it worked as well. The pliofilm machine was installed on the second floor of an old school building on Prospect street. It was operated by Ray Lauzon.
