         7 . A cutting ring for a cutting roller for quarrying, said cutting ring defining an axial direction and comprising a plurality of cutting inserts disposed in cutting insert seats, said cutting insert seats formed as cutting insert grooves that are continuous in the axial direction. 
     
     
         8 . The cutting ring of  claim 7 , wherein said cutting inserts fill their respective cutting insert grooves completely and terminate outwardly flush with intermediate web portions formed between adjacent cutting insert grooves. 
     
     
         9 . The cutting ring of  claim 7 , wherein said cutting inserts are disposed in a raised outer portion of said cutting ring. 
     
     
         10 . The cutting ring of  claim 7 , wherein each said cutting insert groove has wedge insert surfaces that are inclined toward each other from radially inward to radially outward. 
     
     
         11 . The cutting ring of  claim 7 , further comprising a solder layer present between each said cutting insert and each respective cutting insert groove. 
     
     
         12 . A cutting roller for quarrying, including at least one cutting ring of  claim 7 . 
     
     
         13 . The cutting ring of  claim 8 , wherein said cutting inserts are disposed in a raised outer portion of said cutting ring. 
     
     
         14 . The cutting ring of  claim 8 , wherein each cutting insert groove has wedge insert surfaces that are inclined toward each other from radially inward to radially outward. 
     
     
         15 . The cutting ring of  claim 9 , wherein each cutting insert groove has wedge insert surfaces that are inclined toward each other from radially inward to radially outward. 
     
     
         16 . The cutting ring of  claim 8 , further comprising a solder layer present between each said cutting insert and each respective cutting insert groove. 
     
     
         17 . The cutting ring of  claim 9 , further comprising a solder layer present between each said cutting insert and each respective cutting insert groove. 
     
     
         18 . The cutting ring of  claim 10 , further comprising a solder layer present between each said cutting insert and each respective cutting insert groove. 
     
     
         19 . A cutting roller for quarrying, including at least one cutting ring of  claim 8 . 
     
     
         20 . A cutting roller for quarrying, including at least one cutting ring of  claim 9 . 
     
     
         21 . A cutting roller for quarrying, including at least one cutting ring of  claim 10 . 
     
     
         22 . A cutting roller for quarrying, including at least one cutting ring of  claim 11 .
