PROBLEM TO BE SOLVED: To provide a device for forming a slit, in which adjustment of a position or the width of a slit is facilitated and the labor and time of maintenance can be reduced when a member for forming the slit is cleaned or exchanged.SOLUTION: The device 122 for forming the slit is constituted by disposing two positioning units 122a, 122b, each of which includes an adjusting member 123 and a fixing member 124, so as to be opposed to each other so that the slit 27 is formed between the fixing members 124 themselves. Each of the positioning units 122a, 122b includes a position adjustment mechanism for adjusting a disposal position of the adjusting member 123 so that the width of the slit 27 can be adjusted by adjusting the disposal position of the adjusting member 123. The fixing members 124 can be fixed freely detachably to the adjusting member 123. Each of the positioning units 122a, 122b includes a positioning means 58 for deciding a relative position between the fixing member 124 and the adjusting member 123 and a position reproducing means 59 for repeatedly reproducing the relative position when the fixing member 124 and the adjusting member 123 are detached.SELECTED DRAWING: Figure 9 |
