ABSTRACT:
Sheet material such as carpet is moved along its length between lower and upper rollers of a cluster or rotating rollers. The rotating rollers form the sheet material into a spiral roll, and as the size of the spiral roll of sheet material increases, it urges one of the upper rollers of the cluster to open up away from the other rollers to form an upwardly facing concave arrangement of rollers, and as the spiral roll of sheet material continues to increase, it becomes supported on the upper rollers of the cluster with its free end extending downwardly between the upper rollers so that the upper rollers exert roll-up forces about a major portion of the circumference of the spiral roll of sheet material. When a predetermined length of sheet material has been accumulated in the spiral roll, the movement of the sheet material is stopped, the material is cut, and the upper rolls in the cluster of rolls are manipulated so as to eject the accumulated spiral roll of sheet material from the cluster of rollers.
