Abstract
In a book binding operation, opened covers are brought into alignment with moving book blocks by a feed system which applies a pneumatic hold-down force to the moving covers. This hold-down force provides for a braking effect which varies as a function of the characteristics of the cover, the braking effect minimizing the chances of overshoot. The hold-down force also provides a stiffening effect, in the direction of cover movement, which varies as a function of cover thickness and minimizes the possibility of crushing.
