An adjustable gripper system for releasably holding at least one sheet against a surface includes an adjustment body, a gripper connected thereto for holding the sheet against the surface, and a cam follower to be actuated by a cam. The cam follower is connected to the adjustment body and displaces the adjustment body dependent upon a cam position, which correspondingly displaces the gripper along the surface. The system can be part of a sheet-collating pocket having a top portion, forward and rearward walls pivotally connected to one another and defining a sheet-receiving opening, which pocket can be part of a sheet-collating machine having the cam, a conveyor, a sheet feeding device, and other pockets. A method for adjusting the grippers positions the cam in the pocket path to contact each and selectively displace the gripper holding portion with dependent upon the cam position while the cam and pocket contact.
