Duplicator - Fordigraph Spirit, Single Drum, Electric, Model 20, 1990s Object Reg. No: ST 046522

An electrically driven spirit duplicator.

The spirit duplicating method is also referred to as the direct, or fluid, process. The master copy is prepared by typewriter, handwriting, punched card, or computer-printing devices. Master copies can also be prepared by copying machines and microfilm reader-printers. The master sheet is then fastened to a rotating drum. As copy sheets, slightly moistened by a special liquid, are brought into direct contact with the master sheet, a minute amount of the carbon is transferred to them, resulting in finished copies. Multicolour duplication in one operation is possible. A further advantage of the spirit process is that information can be added to or deleted from the master. Up to 300 copies can be made from one master sheet. This machine is entirely mains operated.

I worked for a firm of office suppliers in the 80s and they were owned by Frank R Ford of Droitwich in Worcestershire which made the Fordigraph spirit duplicator.

Frank R Ford was my grand father and was the inventor of the Fordigraph spirit duplicator. the company moved from Birmingham to Droitwich and my father Ronald m Ford was the Managing Director until his retirement. I trained at FRF in engineering ,primarily in the drawing office and Research and Development. Nice to see the name still exists
