Abstract
Apparatus for trimming the front, head and foot ends of brochures has a stationary platform which supports one brochure at a time. A first knife which trims the front end of the brochure on the platform descends in a vertical plane ahead of two additional knives which thereupon simultaneously trim the head and foot ends of the same brochure as soon as the first knife completes the trimming of the front end. The first knife is pivoted forwardly and away from the additional knives while the additional knives move toward and trim the brochure on the platform. This insures that the first knife is held out of the way while the additional knives move to positions in which their forward ends extend beyond the trimmed front end of the brochure.
