Abstract

Abstract In an apparatus for the continuous pressing and decatizing of fabric, a pressure belt serves to move a fabric undergoing treatment around a rotatably-mounted and heatable cylinder. The pressure belt directly contacts the fabric to press it against the cylinder. The surface of the pressure belt is arranged to be heated by a heating roller around which the belt passes prior to passage around the cylinder. The cylinder and heating roller can be independently heated to different temperatures to produce a temperature differential across the fabric as it is pressed. As a result, moisture condensation preferentially occurs on one side of the fabric causing luster reduction on that side of the fabric.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 164 words
In an apparatus for the continuous pressing and decatizing of cloth and fabric material, an arrangement comprising a rotatably-mounted, heatable cylinder, having a smooth surface, controllable first heating means arranged to heat said cylinder, a pressure belt in direct contact with material undergoing treatment to press said material into direct contact with the smooth surface of the cylinder, rollers for circulating the pressure belt, said rollers including a roller arranged upstream of the cylinder in the direction of belt circulation, second heating means arranged to heat the said upstream roller whereby to heat the pressure belt prior to passage around the heatable cylinder, control means for controlling the temperature of the second heating means independently of the first heating means whereby an adjustable temperature differential is set up across the material as it is pressed between the smooth surface of the cylinder and pressure belt, and a moisturizing device arranged upstream of the said cylinder to moisturize material prior to passage around the cylinder.
Claim 2
Dependent Claim 164 words
In an apparatus for the continuous pressing and decatizing of cloth and fabric material, an arrangement comprising a rotatably-mounted, heatable cylinder, having a smooth surface, controllable first heating means arranged to heat said cylinder, a pressure belt in direct contact with material undergoing treatment to press said material into direct contact with the smooth surface of the cylinder, rollers for circulating the pressure belt, said rollers including a roller arranged upstream of the cylinder in the direction of belt circulation, second heating means arranged to heat the said upstream roller whereby to heat the pressure belt prior to passage around the heatable cylinder, control means for controlling the temperature of the second heating means independently of the first heating means whereby an adjustable temperature differential is set up across the material as it is pressed between the smooth surface of the cylinder and pressure belt, and a moisturizing device arranged upstream of the said cylinder to moisturize material prior to passage around the cylinder.
Claim 3
Dependent Claim 93 words
The arrangement as set forth in claim 1, in which the first and second heating means are steam heating means, each provided with a respective steam volume regulator, the steam regulator associated with the first heating means being controlled by a temperature regulator connected to a temperature sensor arranged to measure the surface temperature of the cylinder, and the steam regulator associated with the second heating means being controlled by a temperature regulator connected with a temperature sensor arranged to measure the surface temperature of the belt in the region of the cylinder.
Claim 4
Dependent Claim 25 words
The arrangement as set forth in claim 1, in which the moisturizing device has one or more steam boxes through which the material is moved.
Claim 5
Dependent Claim 23 words
The arrangement as set forth in claim 1, in which the moisturizing device has a steam cylinder through which the material is moved.
Claim 6
Dependent Claim 30 words
The arrangement as set forth in claim 1, including carrying rollers for moving the material through the moisturizing device, the rollers being arranged to be driven at independently settable speeds.
Claim 7
Dependent Claim 25 words
The arrangement as set forth in claim 5, including non-contact sensors arranged to control said carrying rollers in dependence on the speed of the material.
Claim 8
Dependent Claim 21 words
The arrangement as set forth in claim 1, including a carrying belt for carrying the said material through the moisturizing device.
Claim 9
Dependent Claim 33 words
The arrangement as set forth in claim 1, in which the roller of said belt circulating rollers arranged downstream of said cylinder in the direction of belt circulation, constitutes a belt drive roller.
Claim 10
Dependent Claim 23 words
The arrangement as set forth in claim 1, in which one said belt circulating rollers serves as a tensioning device for the belt.
