          Application No. 08/864,947                                                  


          to end into a unitary line of any desired length without the                
          use of metallic coupling members.                                           


               To prepare the ends of Galloway's hose sections S, S' for              
          splicing the sections are first, squared off so that the ends               
          1, 1' of their inner tubes or linings 2, 2' when brought                    
          together in matching relation will abut in a plane transverse               
          to the hose axis.  Then the cover and the several fabric                    
          layers in each section are progressively cut away at                        
          successively less distances from this plane to expose the                   
          underlying layer.  This results in a stepped formation as                   
          shown in Figure 1.  The ends 1, 1' of the inner liners 2, 2'                
          are coated with a suitable uncured rubber cement, which should              
          be dried at least to tackiness before the ends are brought                  
          together.  Two layers 12, 13 of rubber impregnated 3/8" nylon               
          tape are wrapped tightly about the center of the joint to                   
          substantially fill in the space between steps 3, 3' and                     
          adhered to liners 2, 2' and to each other by a suitable cement              
          (see Figure 2).  Next a layer 14 of rubber impregnated tire                 
          cord fabric tape cut on a bias of about 54/ is laid about tape              
          layer 13 between steps 4, 4' so that the nylon warp yarns form
