A method for gripping, moving and releasing a piece of cloth with a gripper that is initially placed with opposed, movable, coherent, flexible surface parts in contact with the piece of cloth, and the surface parts are moved with respect to each other and with respect to the gripper in a gripping action, in order to pinch and hold on to the piece of cloth. The gripper with the piece of cloth pinched between the surface parts is moved to a different location, wherein the surface parts move in a reverse direction in order to release the piece of cloth. While in contact with the piece of cloth, the opposed surface parts are moved along a path which brings the surface parts both closer to each other and moves them in a direction away from the piece of cloth.
