A gatherer stitcher having a gatherer chain configuration includes roof segments forming a ridge region and drivers having respective stop surfaces and being mounted so as to be adjustable between an operating position and a position pivotable away therefrom. An auxiliary driver is restricted to the ridge region and carried by a respective roof segment directly adjacent the stop surfaces. The auxiliary driver, in the operating position of the adjustable driver, forms a combined stop surface together with the adjustable driver.

A method for precisely aligning a product to be stapled in relation to a stapling device in a gatherer stapler, includes the steps of determining an exact position of the product to be stapled, comparing the determined position with an expected position of the product, supplying a determined positional deviation to a drive as a control variable and performing a compensatory movement by controlling at least one of respective drives of the gathering chain and of the stapling device so that the determined positional deviation is compensated for at the start of the stapling operation. A device for performing the method and a gatherer stapler are also provided.
