Title: Exciting method of synchronous motor for rolling
Inventor: SAITOU TERUHIRO
IPC: H02P23/00
Filed: 1978-08-31
Abstract: PURPOSE: To enable the synchronous motor to be miniaturized by detecting the material to be rolled with the detector on the upper stream side of the rolling mill before it is bitten into the rolling mill, intensifying the excitation of the field system of the synchronous motor then weakening the excitation of the field system after the trailing end of the material to be rolled goes out of the rolling mill.  
     CONSTITUTION: When the material 4 to be rolled is conveyed to a rolling mill by conveying rollers 3, the leading end of the material 4 to be rolled is detected with a detector 5. Next, the signal of the detector 5 is sent to a field control unit 7 of a synchronous motor 2 through a timer 6 to intensity the excitation of the field system of the motor 2 and increase the torque of the motor to the magnitude required for rolling. The timer 6 is beforehand so arranged as to permit time adjustment because there are cases when the conveying speeds of the material 4 to be rolled are not constant. Next, the signal when the trailing end of the material 4 to be rolled goes out of the rolling mill 1 is sent to the field control unit 7 through the timer 6 to weaken the excitation of the field system of the motor 2.

Title: Carrying roll for thin object
Inventor: HARA SHIYOUJI
IPC: B65H27/00
Filed: 1983-06-15
Abstract: PURPOSE:To eliminate the possibility of occurrence of the scratches of film caused by a roll by revolving a free roll synchronizing with the carrying speed of said film. CONSTITUTION:When the carrying speed of film increases, air enters the gap between a roll 11 and said film, and said film comes to rise from the face of said roll. Both ends in the width direction of said film are in contact with the atmospheric pressure, so the pressure of rising air gradually decreases to the atmospheric pressure at said ends, and said ends can abut against said roller because of the stretching power of said film. Therefore, said roll 11 revolves by the frictional force between both ends 9 of side-roll 7, synchronizing with the carrying speed of said film. As the central area 10 of said film does not abut on a main- roll 6, said film cannot be scratched.
