la presse à cuvette (f) pour repassage du tissu
-rotary press (calendering machine), for press finishing.
I do not have personal knowledge of this machine, but from the definition it looks like a good bet. The picture in the book shows a large rolling press with much smaller buttons than are in your picture. They are described as "les boutons (m) et volants (m) de commande" or "control buttons and control wheel."

Reference information: Wikipedia - Calender
The calender is a series of hard pressure rollers at the end of a papermaking process (on-line). Those that are used separate from the process (off-line) are also called "supercalenders". The purpose of a calender is to smooth out the paper for printing and writing on it, and to increase the gloss on the surface.
Calenders can also be applied to materials other than paper when a smooth, flat surface is desirable, such as cotton, linens, silks, and various man-made fabrics and polymers such as vinyl and ABS polymer sheets, and to a lesser extent HDPE, Polypropylene and Polystyrene. http://en.wikipedia.org/wiki/Calender
