  • Apparatus for looping belt-like materials
    Patent number: 4613093
    Abstract: An apparatus for looping belt-like materials, including first and second looping units for winding a moving belt-like material helically into first and second coils, with a portion of the belt-like material forming the first coil being drawn out into the second coil. A plurality of support rollers annularly arranged along each of the portions of the wound belt-like material forming the first and second coils, and frames are provided with the support rollers, along with a drive for applying a rotary force to the frames. The support rollers are displaceable in a radial direction of an imaginary circle along which the support rollers are arranged in accordance with variations in diameters of the coils so as to bring the support rollers into contact with the portions of the belt-like material which constitute the coils.
