Abstract
Decatizing apparatus comparison a heated cylinder and a backing cloth applied against the cylinder by means of a thrust belt under high tension. The material to be treated passes between the cylinder and the backing cloth. The cylinder is freely rotatable and is driven by passage of the material, the backing cloth and the thrust belt.
Claims2
A method of continuously decatizing and effectively pressing a fabric material said method comprising:
- providing a feed path for the fabric material;
- providing a rotatable, heated, decatizing cylinder on said feed path having a continuous mirror finish surface;
- providing a moisturizing device on said feed path upstream of said decatizing cylinder, continuously feeding a backing cloth having a dense and smooth surface across said moisturizing device and around said mirror finish surface of said decatizing cylinder, continuously feeding the fabric to be treated along said feed path whereby the fabric passes across said moisturizing device and across said mirror finish surface of said cylinder in direct contact with said mirror finish surface of the cylinder, with the fabric being located between said mirror finish surface of said cylinder and the adjacent said dense and smooth surface of said backing cloth;
- and providing a thrust belt under high tension to thrust said backing cloth and the fabric material towards said mirror finish surface of said cylinder, whereby elongation of the fabric does not occur throughout the period of said direct contact with said mirror finish surface of said cylinder and the fabric thus ironed and pressed has improved handling properties.
