A tension strap for a fibre tensioner of a creel comprises a first portion 60 with a free end 42 for connection to a fibre tensioner; and a second portion 62 with another free end 44 for connection to the creel frame. A third portion 64 extends between and joins the first and second portions. The strap may encircle a fibre holder bearing surface (58, figure 5) to form a looped strap extending around the bearing surface, the loop comprising the third portion. The strap may be plain and be spirally wrapped around the bearing. Alternatively, the strap may comprise a slot of width W1 which accommodates a reduced width portion W2. The strap may be looped by passing the free end 44 through the slot. The strap may be made from rubber, felt, leather or a woven composite. The straps contacting surface preferably has a friction coefficient of at least 0.5 and may have longitudinal grooves which improve flexibility and aid the dispersal of particles. The strap may be located in a holder bearing track flanked by walls (96). The strap may bear on one to two full circumferences of the holder bearing surface. |
