摘要:Automatic control of the degree of exposure of continuous sheet passingthrough a chamber for a treatment which promotes contraction of the material andhence an increase in the tension in the sheet, by monitoring the degree of tension andmaking corresponding adjustments to the relative positions of guide rollers to vary thepath length. Esp. for treating textiles to ammonia vapour from a tray of liquid NH3supported alongside the textile path through a vapour sealed chamber, to vary thedegree of exposure to compensate for variations in fabric thickness or density andgenerate a uniform degree of fibres contraction. A simpler and more responsivetechnique for controlling the degree of exposure than systems based on changing drivemotor speeds for the rolls transporting the sheet through the chamber.
