Abstract

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.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 89 words
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°.
Claim 2
Dependent Claim 89 words
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°.
Claim 3
Dependent Claim 18 words
A machine according to claim 1, wherein each backing cloth is freely removable from its associated pressure strip.
Claim 4
Dependent Claim 18 words
A machine according to claim 2, wherein the backing cloths are in the form of endless, joint-free bands.
Claim 5
Dependent Claim 16 words
A machine according to claim 3, wherein the backing cloths are composed of a satin fabric.
Claim 6
Dependent Claim 18 words
A machine according to claim 1, further comprising tensioning rollers, said pressure strips passing over the tensioning rollers.
Claim 7
Dependent Claim 14 words
A machine according to claim 5, wherein each pressure strip is composed of steel.
Claim 8
Dependent Claim 24 words
A machine according to claim 1, further comprising a sleeve, said sleeve being disposed around the decatizing cylinder and being in direct contact therewith.
Claim 9
Dependent Claim 13 words
A machine according to claim 7, wherein the sleeve is a fabric sleeve.
Claim 10
Dependent Claim 129 words
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.
Claim 11
