An apparatus (30) and method is provided for holding and tacking an elongate material (12) onto a body (14), which body (14) may be toroidal in shape. The material (12) is applied to the body (14) by means of a shuttle (22) rotating about the body (14) in a plane transverse to a plane containing the body (14). The apparatus (30) includes a tacker arm (76) having a clamping means (104) for clamping and unclamping the end of the material (12), extending from the shuttle (22), to the arm (76). The arm (76) is pivotally mounted on a carriage (58) for movement between a first position, wherein the material (12) clamped to the arm (76) is held against the body (14), and a second position, spaced from the body (14). In the first position of the arm (76), the body (14) will move the arm (76) until the clamping means ( 104) unclamps the material (12) whereupon the arm (76) is pivoted to the second position. The carriage (58) is reciprocable for moving said arm (76) between said second position, spaced from the body (14), and a third position, remote from the shuttle (22). |
