This Polygraph Y6R is a used book binder — more specifically, a corner rounding machine, also known as a corner cutter — designed to trim the corners of stacked paper, book covers, cards, and similar materials into a smooth, rounded profile. Polygraph is a well-established German manufacturer with a long history of producing bookbinding and print-finishing machinery for the printing and publishing industries.
The machine carries serial number 246292 and is fitted with a Gerdes straight knife, a reputable blade configuration commonly associated with clean, precise corner cuts. The maximum stack height is 55 mm, meaning the machine can process a substantial thickness of material in a single operation, making it well suited to medium-volume production work. The stroke measures 65 mm, which defines the travel of the cutting mechanism through each cycle.
Operation is entirely manual, controlled via a hand lever, and the machine is a table model — compact and self-contained, requiring no dedicated floor space beyond a suitable work surface. This configuration keeps the machine simple to set up and maintain, with no electrical supply needed.
The machine is located in Emskirchen, near Nuremberg, Germany, is available immediately, and can be inspected and tested on site.
