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.
Claims10
A machine for producing a plurality of lengths of sheet material from a roll of the material comprising a frame, fabric supporting means rotatably mounted on the frame, said fabric supporting means including at least three members spaced about the axis of rotation of said means and extending substantially parallel thereto, the members being mounted for selective movement towards or away from said axis to selectively vary the spacing of the members relative to each other, clamping means on at least one member to clamp the end of a length of sheet material to the said at least one member, driving means to rotate said members about said axis to thereby wind sheet material about the members so that one or more layers of material are supported by the members, and means for cutting said layers substantially parallel to the members to produce a plurality of lengths of said material of substantially equal length.
A machine for producing a plurality of lengths of sheet material from a roll of the material comprising a frame, a shaft mounted for rotation relative to the frame, at least two collars axially movable along the shaft, means for locating the collars at any predetermined axial position along the shaft, a plurality of fabric supporting members spaced around the shaft, the members being adjustably supported in spaced relationship to the shaft by pivoted arms extending between each collar and each member, flange means rotatably mounted on the shaft adjacent each end thereof, means interconnecting the flange means and the collars to prevent relative rotation therebetween without restricting axial movement of the collars along the shaft, secondary arms extending from said flange means and attached to said pivoted arms intermediate the ends thereof, and driving means for rotating said flange means, interconnecting means, shaft, collars, arms and members relative to said frame.
