       3 ) Plant according to  claim 1 , characterized in that the said structure is provided with a section intended for frontally closing the tank of the respective machine when the structure is disposed thereinside.  
   
   
       4 ) Plant according to  claim 1 , characterized in that the said structure is provided with bars for supporting the baskets.  
   
   
       5 ) Plant according to  claim 1 , wherein each of said baskets is provided with a racer carried by a corresponding axis and with a nozzle for the injection and recirculation of the dyeing bath, characterized in that the said baskets-holding structure and the tank of each dyeing machine are provided with means for supporting and driving said axis and with means for feeding the dyeing bath to said nozzle.  
   
   
       6 ) Plant according to  claim 1 , characterized in that the said baskets-holding structure is provided with wheels resting on a horizontal plane.  
   
   
       7 ) Plant according to  claim 1 , characterized in that the said baskets parking region is subdivided into two areas sideway of the said machines.  
   
   
       8 ) Plant according to  claim 1 , characterized in that the number of said baskets is higher than that of said machines.  
   
   
       9 ) Machine for dyeing textile materials, of a type comprising a tank inside which the dyeing of the materials held in a basket takes place, and which is associated with means for the preparation and supply of a corresponding dyeing bath, characterized in that it comprises a baskets-holding structure able to be positioned within the respective tank and respectively removed therefrom; the said baskets-holding structure intended for supporting a materials-holding basket removably disposed thereon.  
   
   
       10 ) Machine according to  claim 9 , characterized in that the said structure is provided with a section intended for frontally closing the respective tank when the structure is disposed thereinside.  
   
   
       11 ) Machine according to  claim 9 , characterized in that the said structure is provided with bars for supporting the baskets.  
   
   
       12 ) Machine according to  claim 9 , wherein each of said baskets is provided with a racer carried by a corresponding axis and with a nozzle for the injection and recirculation of the dyeing bath, characterized in that the said baskets-holding structure and the said tank are provided with means for supporting and driving said axis and with means for feeding the dyeing bath to said nozzle.  
   
   
       13 ) Machine according to  claim 9 , characterized in that the said baskets-holding structure is provided with wheels resting on a horizontal plane.  
   
   
       14 ) Basket for holding textile materials to be dyed, characterized in that it comprises a racer provided with a respective axis of rotation, a nozzle associated with means for feeding a dyeing bath and a structure for supporting said racer and said nozzle, the said structure being provided with feet to allow them to rest onto a structure in operating condition inside the tank of a dyeing machine, and to rest onto a supporting structure in stand-by or parking condition outside of said machine.  
   
   
       15 ) Materials-holding basket according to  claim 14 , characterized in that it comprises a sheet structure with two side panels having a substantially triangular profile with horizontal base between which a perforated cradle is disposed whose height is less than that of the side panels, that a foot is provided in correspondence of each of the two vertexes at the base of each of said side panels, that said axis is supported, above said cradle, by the said side panels so that each side of the axis will result projecting, by a preset extent, from a corresponding appendix exhibited by each of said side panels, that the ends of the axis projecting from the side panels are shaped as power takeoffs, that each of said appendixes forms a preset angle to the vertical middle axis of the respective side panel so that the racer results offset with respect to the two side panels, that the said side panels support the said nozzle for the injection and recirculation of the dyeing bath by means of two pipes disposed on opposite sides with respect to the nozzle and each of which, on one side, leads to the nozzle and, on the opposite side, presents a sleeve complementary projecting on the outer side of the respective supporting side panel further down with respect to the axis of racer, that the said nozzle results on the opposite side of the racer with respect to the side panels, so that if the nozzle is on the right, the racer is on the left, and vice versa.  
   
   
       16 ) Materials-holding basket according to  claim 15 , characterized in that only one of said pipes is active, that is, utilized, when the basket is in operative condition inside the said machine.
