Abstract
An apparatus for trimming book blocks has at least a first lateral blade for performing a first lateral edge trim. The first lateral blade is attached to a movably mounted first lateral blade holder. A second lateral blade is provided for performing a second lateral edge trim. The second lateral blade is attached to a movably mounted second lateral blade holder. The blade holders have individual drives that are mechanically independent of one another.
