ABSTRACT:
Arrow fletchings (42,102) disclosed have curved vanes (50,114) inclined inwardly in a rearward direction to provide pockets (54,118) for restricting air flow while allowing vane flexing in a manner that moderates drag in response to wind changes. One fletching embodiment (42) is preferably made by plastic extrusion and a subsequent heat forming process and includes a vane (50) whose inner portion projects radially from its foot (44) and whose outer portion define its curved pocket (54). Another fletching embodiment (102) made from sheet plastic includes a vane (114) that projects tangentially from the arrow shaft on which its foot (104) is mounted and is curved to define the pocket (118) that restricts air flow. A fixture (68) for heat forming the pocket of the one fletching embodiment (42) and a method for making the other fletching embodiment (102) are also disclosed.
