ABSTRACT:
An apparatus for trimming folded multi-sheet printed products along the bloom edge and along each of the opposite side edges of each product. The apparatus comprises a first cellular wheel (2) which is mounted for rotation about a vertical axis and which receives the products in upwardly open cells and trims their bloom edges. A second cellular wheel (4) is mounted for rotation about a horizontal axis and receives the products from the first wheel in radially open cells and trims the products along their opposite side edges. Each wheel mounts first blade members (26;36) mounted along an edge of each cell, and a fixed counter blade (29;39) is provided which engages the first blade members upon rotation of the wheel. The wheel also includes an annular running surface (47), and the counter blade is connected to a guide member (46) which is positioned to engage the running surface.
