Abstract

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.
