<p>Device for gripping in formation a number of objects 1a... 1d; 2a...2d; 3a...3d), such as tiles, lying on either side of both a first (horizontal) reference line (X) and a second (vertical) reference line (Y) at right angles thereto, with gripper heads (12a...12d; 13a...13d) procided on at least one set of radially arranged supporting arms (14a... 14d; 15a... 15d) movable in the longitudinal direction and, starting with the supporting arms (5) closest to the second reference line (X), including with the first reference line successive angles the tangent of which varies according to the series 1, 1/3, 1/5, 1/7 etc., while the extent of movement of the respective arms, starting with the supporting arm closest to the second reference line (Y), is successively equal to: 2ROOT (<a>/2)<2> + (<a>/2)<2>; 2ROOT (<a>/2)<2> + (<3a>/2)<2>; 2ROOT (<a>/2)<2> + (<5a>/2)<2>; 2ROOT (<a>/2)<2> + (<7a>/2)<2><-><-></p> |
