摘要： An apparatus for looping belt-like materials, i.e. strips (1), comprising first and second looping units for winding a moving belt-like material helically into first and second coils (23, 30), a means for drawing out the portion of the belt-like material (1) which constitutes the first coil (23), into the second coil (30), a plurality of support rollers (24, 25) arranged annularly along each of the portions of the wound belt-like material (1) which constitute the first and second coils (23, 30), frames (54) provided with the support rollers (24, 25), driving means for applying the rotary force to the frames, and means for applying the rotary force to the frames, and means for displacing the support rollers (24, 25) in the radial direction of an imaginary circle, along which the support rollers (24, 25) are arranged, in accordance with variations in the diameters of the coils (23, 30) so as to bring the support rollers (24, 25) into contact with the portions of the belt-like material (1) which constitute the coils (23, 30), the support rollers (24, 25) being arranged annularly along inner circumferential surfaces of the coils (23, 30), the drawing means being provided with a plurality of small-diameter rollers (27, 28), which are arranged along a curved surface (26) of an imaginary cone or cylinder in such a manner that the small-diameter rollers (28) can be rotated in the same direction, in which the belt-like material (1) is drawn out. When the above-described construction is employed, slipping can be prevented from occurring between layers of a strip (1), i. e. the portions of a belt-like material which form the coils (23, 30), while the strip (1) is moved, and a high-quality strip can be obtained.
