  • Patent number: 3940084
    Abstract: A machine for producing a number of lengths of fabric or similar material comprises a frame supporting a sub-frame for movement thereon. The sub-frame causes an adjustable winder comprising a shaft rotatable in bearings on the sub-frame and at least three supporting members parallel to but spaced from the shaft and spaced about the axis of rotation. The supporting members are carried by the shaft and the radial spacing thereof is variable to thereby vary the distance between the supporting members. At least one of the members has means for gripping one end of a sheet of material and driving means are associated with the supporting members to rotate the members about the shaft axis to thereby wind the sheet material around the members.
