Polychrome Stencil History... by Mr. Bob Gumbinner

At 94 years young, Mr. Bob Gumbinner is probably the only living witness and participant of early Polychrome activities.     Here is his account of how Polychrome started stencil business which was the core business for Polychrome until offset  business took over later on.        Many Polychrome Alumni may never have heard of the stencil business history.        Some old timer may recognize the names of early contributors to the company.     Thank you very much Mr. Gumbinner for this valuable contribution.      

Polychrome Stencil History

In the late 1930s Mr. Halpern met Louis Mestre a cigar smoker from Cuba. They formed a company and with a man; who later had a stencil factory in Middletown Connecticut, to build the Style stencil duplicator.
He hired Fred Pollack, who had made stencils in Austria and started to coat hand made Japanese yoshino tissue in a loft in lower Manhattan--near Gramercy Park
where he lived. The coating solution was prepared in Monmouth NJ,
The Yoshino tissue was hand made in sheets and girls would hang the sheets
on bars which would move them over a coating roller and through a dryer.
Robert McCabe was hired to sell the product. Later McCabe became the New York City Polychrome office manager then moved to Mexico City to establish Polychrome Mexico to make stencils and offset plates.
In 1946 when I joined Polychrome had moved into gas company property in Yonkers. It had a one and a half story building at the corner of (2) Ashburton Ave and Alexander Street and a brick building across the entrance with sheds adjoining it. Dexter Paper Company who was making tea bag tissue working with Gestetner learned that using an uphill Fourdrinier could be used to make a open weave paper with squarage that could be used for stencils. As this was available in rolls, with the assistance of Fred Hozeny we built the equipment to coat and windup the stencils eliminating the girls who mounted the stencils on the bars. These coaters were designed to coat rolls wide enough to be split in two to be mounted.As the one coating that had been used did not have all the properties we wanted Fred Hozeny and I added three more coating sections to the stencil coating tunnels. I worked with the lab technicians to develop these coatings: The main stencilizable coating, a thin coating to minimize type filling, an anti static coating and a matte finish top coat.
We prepared the pigments for the stencil coating solutions in the building across the yard and the coating solutions in the shed next door. Putting them in drums to transport to the coating room, which we eventually air conditioned. We had a small kettle in which we melted the waxes and mixed them with some of the oils.
Originally the coated rolls were slit, then rolled on a drum and cut to the proper size to be mounted. Mr. Mestre built a machine to take a roll of backing sheet paper, oil it cut a thumb hole, perforate it. apply a glue line and bring the stencil sheet and backing sheet together. An intermediate sheet such as a carbon paper could be included. I was then cut 81/2” or 9” wide. It was then sent at a right angle down a line where the headinf was punched., the backing tab printed, and the scale printed on the stencil We developed an ink based on paralac to be able to print the scale on the stencil sheet. Later Luis Mestre with Ray Lauzon built a machine to apply a sheet of pliofilm or a pliofilm tab and interleaver over the mounted stencil.
Originally most of the sales, besides the New York office were to the government and private dealers. Mr. Halpern convinced Abe Samuels who owned Speed-O-Print and made stencils on Larchmont Street in Chicago to turn over the operation to Polychrome; and sell the equipment and supplies to Polychrome.
Later when the A. B. Dick agreement with Gestetner was over. Sigmund Gestetner arranged for Polychrome to make the stencil for the American Market.
A few years later the Vertex Company in Montvalle New Jersey which was making spirit carbon collating machines, designed stencil mounting and collating equipment, which combine all the operations in a straight through process including mounting the pliofilm tab. Polychrome bought two of these collators.
