    • 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. The support rollers are annularly arranged along inner circumferential surfaces of the coils, with the drawing of the portion of the first coil being effected by a plurality of small-diameter rollers, arranged along a curved surface of an imaginary cone or cylinder in such a manner that the small-diameter rollers can be rotated in the direction in which the belt-like material is drawn out.
    • 用于环绕带状材料的装置,包括用于将移动的带状材料螺旋地卷绕到第一和第二线圈中的第一和第二环形单元,形成第一线圈的带状材料的一部分被拉出到第二线圈中 。 沿着形成第一和第二线圈的卷绕带状材料的每个部分环形布置的多个支撑辊以及框架设置有支撑辊以及用于向框架施加旋转力的驱动器。 支撑辊可以沿着假想圆的径向方向移动,沿着该假想圆的径向方向,支撑辊根据线圈的直径的变化而布置,以使支撑辊与构成带状材料的部分相接触 线圈 这些支承辊是沿线圈的内圆周表面环形排列的,第一线圈的一部分的拉伸是通过多个小直径的滚筒来实现的,多个小直径的滚筒沿着假想的圆锥体或圆筒的曲面以这种方式 小直径辊可以沿着带状材料被拉出的方向旋转。
