[Class 83 (iv)] In a machine for coiling wire for lamp filaments &c., a wire gripping device clamps the wire to a rotatable mandrel at any rotative position of the coiling spindle. A mandrel 5 is secured in a chuck 7 on a rod 8 reciprocated within a coiling spindle 2 which carries a head 9 to which is attached a clamp member 13 engaging another clamp member 18 on a head 10 rotated by a pin 26 with the spindle 2. The clamps 13, 18 are separated against the urge of a spring 23 for insertion of the wire.
