等帯状物の横延伸倍率制御装置。 In the lateral stretching magnification control device consisting of a thickness measuring device 30 before lateral stretching, a lateral stretching device 15, and a thickness measuring device 28 after lateral stretching, a stretching magnification calculator 29, a comparator 31, a stretching magnification setting device 32, and a rail pattern selector 33 are used.
, the rail pattern setter 34 , the width-setting motor M1 ... Mn of the lateral stretching device, and the width-setting screw S1 ...S
The stretching magnification calculator 29 inputs the signal from the thickness measuring device 30 before lateral stretching and the signal from the thickness measuring device 28 after lateral stretching, calculates the stretching magnification, and sends the calculation result to the comparator 31. The comparator 31 inputs the signal from the draw magnification setting device 32 and the signal from the draw magnification calculator, outputs the difference between both signals to the rail pattern selector 33, and outputs the difference between the two signals to the rail pattern selector 33. 33 inputs the signal from the rail pattern setting device 34 and the signal from the comparator 31, selects a preset rail pattern so that the stretching ratio approaches the target value, and drives the tenter motor M of the lateral stretching device. 1
... Mn , and the width adjustment screw S1 ... Sn
1. A transverse stretching magnification control device for a strip-like material such as a film, which is driven by tenter motors M1 ... Mn to adjust a rail pattern.
