A traction device ( 102 ) for use in picking or gripping or packaging objects. The traction device ( 102 ) draws an object into its interior. It comprises a surface ( 16 ) of deformable material, shaped substantially as a tube with an end portion turned inside-out, forming an opening to an interior, and an actuator ( 6 ) for moving the surface to draw the object into the interior. The surface of deformable material may be a part of a fluid-filled toroid body ( 10 ). The traction device can be used in combination with a bag to bag an object.
