<p>PROBLEM TO BE SOLVED: To provide a stretching apparatus which can control the elevation velocity, velocity pattern, and stop position of a stretch rod simply and correctly and be made less expensive and compact. SOLUTION: An apparatus is equipped with an input means 12 for inputting the elevation velocity, velocity pattern, and stop position of a stretch rod 4 as setting values, a position sensor 13 for measuring the position of the stretch rod 4, an operation means 14 for outputting the control signal of a servomotor 10 on the basis of information on the position of the stretch rod 4 from the position sensor 13, a servo amplifier 15 for controlling the servomotor 10, and an encoder 16.</p> |
