Durable transfer roll core and method of making and using the same

Abstract

A durable transfer roll core may comprise an elongate body comprising a groove, the elongate body having an elongate body longitudinal axis. First and second ridges may be on each side of the groove and may be asymmetrical relative to the groove longitudinal axis.

What is claimed is: 
     
         1 . A durable transfer roll core, comprising:
 an elongate body having a main surface comprising a groove, the elongate body having an elongate body longitudinal axis;   wherein the groove has a groove longitudinal axis;   wherein a first ridge runs along a first side of the groove;   wherein a second ridge runs along a second side of the groove, wherein the second side is opposite the first side of the groove; and   wherein the first ridge is asymmetrical to the second ridge relative to the groove longitudinal axis.   
     
     
         2 . The durable transfer roll core of  claim 1 , wherein the groove comprises a Groove Length from about 1 to about 112 inches. 
     
     
         3 . The durable transfer roll core of  claim 1 , wherein first and second ridges have different heights. 
     
     
         4 . The durable transfer roll core of  claim 1 , wherein the roll is selected from a material consisting of plastic, thermoplastic, metal, carbon filaments, thermoplastic resins, and combinations thereof. 
     
     
         5 . The durable transfer roll core of  claim 1 , wherein the durable transfer roll core has a Core Length from about 20 to about 110 inches. 
     
     
         6 . The durable transfer roll core of  claim 1 , wherein the durable transfer roll core has an Outer Core Diameter from about 10 to about 19 inches. 
     
     
         7 . The durable transfer roll core of  claim 1 , wherein the durable transfer roll core has an Inner Core Diameter from about 9 to about 18 inches. 
     
     
         8 . The durable transfer roll core of  claim 1 , wherein the durable transfer roll core has a spiral groove pattern. 
     
     
         9 . The durable transfer roll core of  claim 1 , wherein the durable transfer roll core comprises multiple groove segments. 
     
     
         10 . The durable transfer roll core of  claim 9 , wherein the multiple groove segments are staggered from each other. 
     
     
         11 . The durable transfer roll core of  claim 1 , wherein the durable transfer roll core is cylindrical. 
     
     
         12 . The durable transfer roll core of  claim 1 , wherein the groove comprises a Groove Width from about 0.01 to about 0.3 inches. 
     
     
         13 . The durable transfer roll core of  claim 1 , wherein the groove comprises a Groove Width from about 0.02 to about 0.1 inches. 
     
     
         14 . The durable transfer roll core of  claim 1 , wherein a first ridge height of the first ridge is from about 0.001 to 0.08 inches. 
     
     
         15 . The durable transfer roll core of  claim 14 , wherein a second ridge height of the second ridge is from about 0.003-0.06 inches. 
     
     
         16 . The durable transfer roll core of  claim 1 , wherein the first ridge has a Ridge Height at least 25% greater than the second ridge. 
     
     
         17 . The durable transfer roll core of  claim 1 , wherein the first ridge has a Ridge Width at least 25% greater than the second ridge. 
     
     
         18 . The durable transfer roll core of  claim 1 , wherein the Ridge Spacing from the first ridge to the second ridge is from about 0.05 to about 0.4 inches. 
     
     
         19 . The durable transfer roll core of  claim 1 , wherein the groove comprises a Groove Depth is from about 0.003 to about 0.1. 
     
     
         20 . The durable transfer roll core of  claim 1 , wherein the roll is selected from a material consisting of high density polyethylene (HDPE), polypropylene random copolymer with modified crystallinity (PP-RCT), polypropylene random copolymer (PP-R), crosslinked polyethylene (PEX), polypropylene, and combinations thereof.
