Pile and similar fabrics are prevented from matting when rolled up by attaching at each side of the fabric a strip having two shoulders, the first of which projects downwardly therefrom beneath the plane of the bottom of the fabric when the fabric is disposed horizontally, and the second of which projects upwardly therefrom above the plane of the top of the fabric. The inner face, i.e. the face toward the center of the fabric and away from the selvage, of the second, or downwardly projecting, shoulder is vertical as is the outer face of the first, or upwardly projecting, shoulder, and these vertical faces are aligned with each other, so when the fabric is rolled up about a horizontal axis the inner face of the downwardly projecting shoulder bears against the outer face of the upwardly projecting shoulder, and the downwardly projecting shoulder is held on the outer side of the upwardly projecting shoulder. The core on which the fabric is rolled has a flange at each end which projects radially away from the axis of the core, and these flanges each have axially outer faces which lie in radial planes. These flange faces are adapted to bear against the inner face of the downwardly projecting shoulder of the strip on the first wrap of the fabric about the core. The planes of the flange faces are spaced apart a sufficient distance axially of the core that the fabric is held taut and lies along a helical, or substantially helical, path around the core axis. The thickness of at least one of the shoulders on each strip measured normal to the plane of the surface of the fabric is at least equal to, and preferably slightly greater than, the thickness of the fabric.
