Abstract

A sheet folding device is provided, the device comprising a body and a folding assembly, the folding assembly having a changeable folding end. A sheet folding kit is also provided, the kit comprising a sheet folding mechanism comprising a fixing body and a folding mechanism, two or more folding ends, and two or more folding blocks. A method of folding a sheet is further provided, the method comprising selecting a folding end of a folding assembly based on the fixing profile and the desired seam.

1 ) A sheet folding device comprising:
 a body comprising an interchangeable folding block;   a pressing assembly pivotally mounted to the body, the pressing member comprising a folding end;   wherein the folding end and the folding block are shaped to fold the sheet to a predetermined shape.   
     
     
         2 ) The sheet folding device of  claim 1 , the folding end being detachably mounted to the pressing assembly. 
     
     
         3 ) The sheet folding device of  claim 1 , the folding end having a shape matching a portion of a desired profile. 
     
     
         4 ) The sheet folding device of  claim 1 , the folding block having a shape matching a portion of a desired profile. 
     
     
         5 ) The sheet folding device of  claim 1 , the body further comprising a movable pressing member adapted to press on the sheet. 
     
     
         6 ) The sheet folding device of  claim 5 , the movable pressing member being interchangeable. 
     
     
         7 ) The sheet folding device of  claim 5 , the movable pressing member comprising a handle. 
     
     
         8 ) The sheet folding device of  claim 5 , the movable pressing member comprising an elongated member selectively maintained at different positions about the body. 
     
     
         9 ) The sheet folding device of  claim 8 , the body further comprising a securing assembly adapted to alternatively lock or release the elongated member in place. 
     
     
         10 ) The sheet folding device of  claim 9 , the securing assembly comprising a passage sliding receiving the elongated member and a locking mechanism pressing or releasing the elongated member in the passage. 
     
     
         11 ) The sheet folding device of  claim 1 , the pressing assembly further comprising a handle. 
     
     
         12 ) The sheet folding device of  claim 11 , the pressing assembly being pivotable about a fulcrum positioned between the handle and the folding end. 
     
     
         13 ) The sheet folding mechanism of  claim 12 , the pressing assembly being movably attached to the body between the fulcrum and the handle. 
     
     
         14 ) The sheet folding mechanism of  claim 1 , the folding block further comprising threaded apertures, the folding block being attached to the body using threaded fasteners passing through the threaded apertures. 
     
     
         15 ) A sheet folding kit, the kit comprising:
 the sheet folding device of  claim 1 ;   one or more additional folding blocks having shapes matching different desired profiles.   
     
     
         16 ) The sheet folding kit of  claim 15  further comprising one or more additional folding ends having shapes matching different desired profiles. 
     
     
         17 ) A method of folding a sheet over a profile, the method comprising:
 mounting a folding block matching the profile to a folding device;   abutting the mounted folding block to a sheet to be folded along the profile;   holding a body portion of the folding device over the sheet to be folded;   pivoting a pressing assembly about the body portion to fold the sheet according to a shape of the folding block.   
     
     
         18 ) The method of  claim 17  further comprising mounting to the folding device a folding assembly matching the fixing profile. 
     
     
         19 ) The method of  claim 17 , further comprising:
 unmounting the folding assembly from the device;   mounting another folding assembly to the folding device, the folding assembly matching a portion of another profile.   
     
     
         20 ) The method of  claim 17  further comprising adjusting height of a pushing member of the folding device to conform with a top surface of the fixing profile. 
     
     
         21 ) The method of  claim 20  further comprising holding sliding the pushing member in relation to the body to adjust height. 
     
     
         22 ) The method of  claim 20  further comprising securing the pushing member to the body. 
     
     
         23 ) The method of  claim 17  further comprising holding a body portion using a first hand of an operator and pivoting the pressing assembly using a second hand of an operator. 
     
     
         24 ) The method of  claim 17 , further comprising:
 unmounting the folding block from the device;   mounting another folding block to the folding device, the folding block matching another profile.
