Abstract
Printed products are stapled by guiding them between a stapling-head arrangement and a staple-closing arrangement. The stapling-head arrangement comprises a number of stapling heads revolvingly moved along a closed revolving path. A section of this closed revolving path thereby extends substantially parallel to the travel path of the printed products. The staple-closing arrangement comprises a number of countersupports likewise moved along a closed revolving path also having a section extending substantially parallel to the travel path of the printed products. A countersupport co-acts in each case with a stapling head to close the respective inserted staple. Consequently, during the stapling operation, the stapling heads and the countersupports run along and cover a certain distance together with the respective printed products to be stapled.
