Title: Underground pipe joint
Inventor: WATANABE CHIKASHI
IPC: G01L21/02
Filed: 1978-01-21
Abstract: PURPOSE: To prevent the damage of a connecting joint by using a supporting fixture to form the inserting margin of an inserting pipe and to release the support against an excess load as a buffer for permitting the inserting of an inserting pipe.  
     CONSTITUTION: A concave part 11 is provided on the contacting face of an elastic fitting ring 10 with an inserting pipe, and connection is given in a contacting face 12 above this concave part 11. When the elastic fitting ring 10 is brought in contact with a catching part 7 as keeping a normal shape, a gap is formed between the top face 6' of the inserting pipe 6 and the inside 7' of the catching part. When an excessive load is given, a stopper part 9 works to release its supporting as a buffer to permit the inserting of the inserting pipe 6, the concave part 11 on the elastic fitting ring 10 of the stopper part 9 is expanded to the outside to form a narrow part 11', and deformed to shape an expanded part 13 for shortening the inserting margin to absorb excessive loads as a buffer.

Then the sheet base material 1 is dried by a dryer 6. Since the base material may be broken if a foreign substance such as resin and thread refuses are allowd to slip inbetween the squeeze rolls rotating in the directions opposite to each other, it is so arranged that, if an overload exceeding a predetermined level is applied to the rolls, the rolls are caused to rotate in the same direction as that in which the sheet base material is moved and allowed to rotate as it has originally been set, and then automatically returned.
