This Challenge CMT-330 is a guillotine — also known as a three-knife trimmer or trilateral cutter — designed to trim the three open edges of bound books, brochures, and similar printed products to a precise finished size. Challenge is a well-established American manufacturer with a long history of producing cutting and finishing equipment for the commercial printing and bookbinding industries.
The machine is configured as an in-line three-knife trimmer, meaning it processes stacks of books or booklets through a sequence of cuts in a single pass, making it well suited to continuous production environments. It carries serial number and was built in 2005. The untrimmed sheet size ranges from a minimum of 178 × 127 mm up to a maximum of 330 × 330 mm, while the trimmed output size spans from 148 × 100 mm at the smallest to 307 × 328 mm at the largest. The maximum stack height accepted is 51 mm, the minimum trim that can be removed is 2.5 mm, and the maximum trim is 152 mm.
In single-stream mode the trimmer operates at speeds of up to 400 cycles per hour, supporting high-volume production runs. The control system stores up to 99 job set-ups, and changeover between set-ups is fully automatic, completing within 20 seconds — a practical advantage where short runs and frequent format changes are common.
This unit is equipped with a tilt in-feed conveyor, a cooling down-elevator, and an exit conveyor, providing a complete integrated transport system for stacked product through and out of the trimmer. The machine is also compatible with in-line connection to a perfect binder, allowing it to receive and trim books directly from a binding line without manual intervention between stages.
The machine is located in the Netherlands, is available from stock, and is offered in used condition at $6,500.
