ABSTRACT:
An improved apparatus for making books and other sheet material articles includes a main conveyor for transporting groups of signatures to a covering station. A cover conveyor transports covers to the covering station where they are sequentially applied to the groups of signatures in a known manner. A first cover feed assembly sequentially feeds covers to the cover conveyor. In the event of a malfunctioning of a first cover feed assembly, a second cover feed assembly is activated to feed a cover to the cover conveyor. A detector for detecting a malfunctioning of the first cover feed assembly is capable of detecting either a failure to feed a cover or the feeding of double covers. In the event that double covers are fed, the double covers are rejected and the second cover feed assembly is activated.
