A base frame (2) carries two adjacent welding tables (15,16) and drive unit (48) with linkages for moving tables in opposite directions. Each linkage has double arm levers (25,26) which rotate on an axis (19,20), and connect to the tables. <??>A base frame (2) carries two adjacent welding tables (15,16) and a drive unit (48) with linkages for moving tables in opposite directions. Each linkage has double arm levers (25,26) which rotate on an axis (19,20). One arm connects with one welding table (15) while the other connects with the second table. When the double arm levers rotate in one direction(B) the welding tables move towards each other and when rotated in the other direction the tables move apart. |
