Method and apparatus for wrapping saw blades or the like
|
Henry E. Wilson |
Grand Junction, CO |
This ingenious machine wraps a bandsaw blade (in an unspecified material, but most likely a heavy paper) and then the blade is folded in the usual way; the act of folding the blade helps to hold the wrapping in place. The wrapped blade is claimed to be less prone to suffering damage from the sawteeth contacting one another while being transported and stored. See also patent 2,624,166. |
