A gathering stapler for printed products of folded printed sheets, has gathering sections extending parallel to one another and circulating transversely to their longitudinal extent, with saddle-shaped rests on which the printed sheets are gathered and stapled. A rotary stapling apparatus has essentially stellately arranged stapling heads driven with the gathering sections in the stapling region in such a way that they meet up. The stapling heads have in each case a staple guide for seating on the printed products, and a push rod, engaging telescopically in the staple guide. The trajectory of the staple guides and the path of circulation of the rests intersect. The staple guides on the rotating carrier of the stapling apparatus can swivel out of a leading position into a trailing position, in relation to their radius, and axe secured displaceably inward against a restoring force.
