PROBLEM TO BE SOLVED: To provide a mechanism for accurately positioning an end of a flexible tube by simple constitution and method without using conventional laser sensing means. SOLUTION: In an apparatus for flatly crushing an end 20a of a flexible tube 20 opened upward by a sandwiching means (temporarily clamping unit 2), linearly sandwiching it and then hermetically sealing it, a positioning jig 7 having a pair of right and left pawls (positioning pawls 7b, 7c) at an upper part of the means 2 to be vertically movable is contained. The pawls 7b, 7c are respectively inserted into gaps 20d, 20e between both the right and left sides in the state that the end is flatly collapsed by the means 2, thereby positioning the end 20a. |
