Dryer and ironer with deformable trough

In a drying and ironing machine having a rotating cylinder the whole cylindrical surface of which being perforated by a large number of openings and completely wrapped by a sleeve-like elastic and permeable outer lining, at least:

• a trough, heated to ironing temperature and against the inner concave and polished surface of which a piece of fabric, drawn by the rotating cylinder and its lining, is applied and simultaneously dried and ironed by friction, said inner concave and polished surface being that of a rectangular metal plate, such as of boiler-type steel sheet metal, which is bent to a radius approximately equal to that of the cylinder with its outer lining when cold, and which is carved on its outside convex surface, by such means as power drilling, with grooves running parallel to the bending axis of this plate and dividing the trough into several equal rigid curved sectors the number of which is equal to that of the grooves plus one, each of these grooves providing, by reduction of the thickness of the said plate, an axis of less resistance to the bending of the trough, and
• adjustable supports of the trough which ensure the tight fit of each of the said sectors of the trough against the outer lining of the rotating cylinder by the slight bending of the trough occurring along each of the said grooves, regardless of the temperature and the expansion of the trough.
