Method for manufacturing erosion control blankets

Abstract

A reinforced or supported core for a roll of erosion control blanket and method of using the same. The core is supported at both lateral ends thereof when the erosion control blanket is attached and during initial stages of winding the erosion control blanket about the core.

1 . A process of manufacturing an erosion control blanket, comprising rolling a fiber attached to a web on a substantially hollow core, the core having a removable support at each end thereof.  
   
   
       2 . The process of  claim 1 , in which the support is an insert.  
   
   
       3 . The process of  claim 1 , in which the support is an exsert.  
   
   
       4 . The process of  claim 1 , further comprising removing each said support.  
   
   
       5 . The process of clam  1 , in which each support is generally cylindrical.  
   
   
       6 . The process of  claim 1 , in which each support comprises steel.  
   
   
       7 . The process of  claim 1 , in which each support comprises a synthetic resin.  
   
   
       8 . The process of  claim 7 , in which a filler is disposed inside each support.  
   
   
       9 . The process of  claim 7 , in which the fiber rolled on the core is stitched to the web.  
   
   
       10 . The process of  claim 1 , further comprising adhering a leading edge of the erosion control blanket to the core.  
   
   
       11 . The process of  claim 10 , further comprising severing a desired length of erosion control blanket, thereby forming a roll of an erosion control blanket.  
   
   
       12 . The process of  claim 11 , further comprising securing the roll of erosion control blanket by banding.  
   
   
       13 . The core of  claim 1  in combination with a pair of the supports of  claim 1 , the inserts supporting each end of the core.  
   
   
       14 . A roll of erosion control blanket, comprising a core, a pair of supports supporting lateral ends of the core, and a length of erosion control blanket wrapped around the core.  
   
   
       15 . The roll of  claim 14 , in which the supports are inserted into the core lateral ends.  
   
   
       16 . The roll of  claim 14 , in which the supports are exserted about the core lateral ends.  
   
   
       17 . The roll of  claim 14 , in which the supports comprise metal, wood, or a synthetic resin.  
   
   
       18 . The roll of  claim 14 , in which the supports are generally cylindrical.  
   
   
       19 . The roll of  claim 18 , in which each of the supports comprises an end wall bonded to a generally cylindrical body.  
   
   
       20 . The roll of  claim 19 , in which the core has a resistance to an external force less that the resistance of schedule  40  polyvinyl chloride tubing.
