PROBLEM TO BE SOLVED: To obtain the positioning apparatus of a foam tentering device capable of easily setting tentering quantity without almost requiring labor when tentering equantity is altered. SOLUTION: A positioning apparatus setting positions where tentering devices 3, 4 must be stopped when foam is tentered by the tentering devices are constituted so that the first and second tentering devices 3, 4 can be moved in a tentering direction accompanied by the rotation of first and second rotary shaft 10, 13 and the rotary shafts 10, 13 are rotated by driving motors 20, 21 to move the tentering devices 3, 4 and the numbers of rotations of the rotary shafts 10, 13 are detected by rotary encoders 22, 23. When the detected numbers of rotations concide with the reference number of rotations corresponding to the preset positions of the tentering devices 3, 4, the movement of the tentering devices 3, 4 is stopped by a control unit 31. |
