PURPOSE:To locate the plate badies accurately by a method wherein each inner end of a pair of arm stocks which are pivoted in their centers is pivoted on nut members which move forward and backward by rotation of a screw shaft and guide pieces are provided vertically on the outer ends of the arm stocks extending from both sides of conueyors. CONSTITUTION:When the plate bodies such as building panels, for example, in two laminated panels are carried on converyors ars 3 consisting of a pair of belts and stopped, then a screw shaft 4 is rotated by a driving device 10 and nut mumbers 7,8 which are screwed on a right twisted portion 5 and a left twisted one 6 respectively are moved in the opposite direction to each other. Two pairs of arm members 14 where one end of each arm member is supported on each nut member 7,8 through pins 12 are rocked around central pivots and facing guide pieces 15 at the extremities move to the inside. Therefare, both sides of the plate bodies are pushed and clamped. If the location of each plate body is not right it will be corrected. |
