However, when such a high-pressure steamer can 4 is subjected to wet heat treatment of a fibrous fiber product,
Since the inside of the steamer can body must be maintained at a high temperature of 150 to 180 ° C., the steamer can body 4 undergoes significant thermal expansion, and usually has the length of the can body 4 (in the horizontal direction in FIG. 1). ) Is set to about 5m,
About 10 cm expansion occurs along its length. In addition, the winding and unwinding mechanism 14 provided in the steamer can 4
The degree of expansion with the can body is different due to the difference in the material and structure from the can body 4, and in the winding and unwinding mechanism 14 of a precise and complicated structure fixed in the steamer can body 4, There is a problem that distortion occurs, and this causes the smooth operation of the winding / unwinding mechanism 14 to be hindered.
