1. Device for dyeing or bleaching textile materials in the rolled up state in a reduced bath, consisting of a cylindrical vessel (10; 110; 210; 310; 410), suitable to be tightly closed by means of a cover (12; 112A; 212A; 312A; 412A), with connections (23; 123; 223; 323; 423 or 24; 124; 224; 324; 424) for the inlet and respectively the outlet of the bath, with holders (30, 31, 32; 130, 131, 132; 230A, 232A; 355, 449) for the rolled up textile materials, such holders being provided with bores, and being suitable to be positioned in a cylindrical zone inside the vessel, with a hollow bath volume reducing body (13; 113; 213; 313; 413), closed, essentially filling the central longitudinal zone left free by the material holders, as well as with a heat exchange system for the control of bath temperature, characterized in that the hollow bath volume reducing body (13; 113; 213; 313; 413) is equipped at its opposite end with respect to the vessel closing cover (12; 112A; 212A; 312A; 412A) with connections (20; 120; 220; 320; 420 as well 21; 121; 221; 321; 421) for respectively feeding and discharging a heat exchange medium, and in its interior is equipped with devices (19; 120A; 220B; 221B; 320B; 321B; 413A, 419A) for circulating the heat exchange medium from the inlet connection to the outlet connection, and that the body of the vessel has a separated cylindrical extension (16; 116; 216; 316; 416), through which the hollow bath volume reducing body (13; 113; 213; 313; 413) passes concentrically, with radial separation, and on which one of the inlet or outlet connections (24; 123; 223; 323; 423) for feeding or discharging the bath is fixed. |
