Archery Paper Tuning Device

Abstract

An archery arrow trajectory evaluation device, that is suspended from above by a pair of cords. Holds a paper roll above a framed structure. The paper feeds down in between the front and back frame. Frames are held together with hollow screws and nuts in each corner. Each nut is adjustable allowing the user to tighten the front and back frame together to hold the paper taut on four sides, but still allowing the paper to pass through from the top of the frame down through to the bottom. Once the paper is held securely between the frames an arrow may be shot through the center of the frames to determine the trajectory of the arrow. If the bow is tuned the arrow will pass through the paper and the tear left behind will be symmetrical. The tear will indicate to the user what adjustments are needed.

1 . An archery arrow trajectory evaluation device, with the use of taut paper the trueness of the arrow flight can be identified, the device comprising:
 a frame designed to suspend from above, is achieved by a pair of laterally spaced cords that are parallel to each other that descend downward to hold and suspend a roll of paper above a frame assembly, the cord lengths are adjustable to accommodate to the height of the user;   a frame assembly consists of a front frame and a back frame, both have holes in the corners that match up so a hollow screw can be placed into the front frame and line up with the back frame and then tighten together with a hollow nut in each corner;   a rod is used to hold a roll of paper, the paper is held horizontally above the frame assembly by loops in the cord above the vertical hollow rod and below the cord stopper, the paper is fed through the top section of the front and back frame down through the frame assembly and out the bottom, at this point the user can pull on the exposed paper to index the paper as needed.   
     
     
         2 . The device of  claim 1  further comprising a removable rod to allow for replacement paper rolls thereon. 
     
     
         3 . The device of  claim 1  in which the front frame is intentionally designed to be slightly taller than the back frame to allow for the user to feed in the paper in between the front and back frame. 
     
     
         4 . The device of  claim 1  in which the front frame has a beveled edge integrated into the back side of lower edge of the window to allow paper with tears to pass through easier. 
     
     
         5 . The device of  claim 1  in which the back frame bottom section of the window area is lower than the front frame, this works in conjunction with  claim 4  to allow paper with tears to pass through without getting stuck or impeded. 
     
     
         6 . The device of  claim 1  in which the back frame is shorter than the front frame is intentionally done to make it easier for the user to feed the paper through the front and back frame. 
     
     
         7 . The device of  claim 1  in which the paper as it passes through the front and back frame is held on all four sides and the paper cannot slide out because the screws act as stopping points and as guides for the paper, the user can adjust the tension of the paper by tightening or loosening the nuts on all four corners this makes the paper taut but still allows the user to pull the paper with minimal effort.
