Abstract
A continuous decatizing machine comprises a perforated decatizing cylinder supplied with steam. A fabric web to be decatized is passed around the cylinder and is pressed against the cylinder by means of backing cloths. Pressure is applied to the backing cloths by means of strips which are impermeable to steam.
Claims9
In a continuous decatizing machine,
- a rotatable, heatable, decatizing cylinder, the cylinder having a circumferential wall provided with holes distributed over the wall,
- means for feeding steam to the decatizing cylinder such that said holes are fed with steam,
- means for feeding material to be decatized around the cylinder,
- backing cloths applied against the material around a portion of the cylinder, and
- two heatable pressure strips, said strips being impermeable to steam, each said strip being applied against a respective backing cloth over an arc of less than 180.degree..

In apparatus for continuously decatizing a fabric web,
- a decatizing cylinder mounted for rotation about its axis, said cylinder having a perforated circumferential wall,
- means for feeding steam to the interior of the cylinder,
- means operative to feed the fabric web around the circumferential wall of the cylinder,
- first and second backing cloths engaging the outer surface of the web around the cylinder, and
- first and second pressure-applying strips associated with the backing cloths, said strips contacting the associated backing cloths and applying pressure to the backing cloths to force the cloths into contact with the web on the cylinder, said strips being impermeable to steam, and being spaced circumferentially around the cylinder to define a gap therebetween for discharge of steam through the web to the surrounding atmosphere.
