The Hunkeler BRM50 is a used book binder — more specifically, a book back rounding machine — designed to form the rounded spine profile that is a defining feature of case-bound and hardcover book production. This process, sometimes referred to as rounding and backing, shapes the gathered book block before it is cased in, giving the finished volume its characteristic curved spine and ensuring the cover sits flush against the pages. Hunkeler is a Swiss manufacturer with a long-standing presence in print finishing and bookbinding equipment, building machinery for commercial printing houses, binderies, and publishing operations.
This example was built in 1978 and carries serial number 4314-9. It is offered in used condition from stock in Emskirchen, near Nuremberg, Germany, and is described as available immediately.
The machine accepts book blocks up to 500 mm in working width and can process book block thicknesses ranging from 0 to 100 mm, making it suitable for a broad range of publication formats from slim pamphlets through to substantial hardcover volumes. Throughput is rated at between 400 and 600 blocks per hour, placing it comfortably in the productive range for mid-volume bindery operations.
The machine is held in stock and available for physical inspection and test running at the Emskirchen location.
