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.
Claims9
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.
