RACK FOR STORING AND DISPENSING ROLLED FLOOR COVERING A rack for supporting a plurality of rolls of sheet material particularly floor covering is defined by a frame structure carrying two chains one at each end with the chains arranged to rotate around upper and lower chain wheels. The chains rotate in synchronism with support hooks carried on the chains and aligned transversely of the chains. A wind up mechanism is attached to the frame at a forward station and comprises a pair of stub rollers one of which is rotated by a hand crank and expandable thereby to engage a tube and wind up material withdrawn from one of the rolls. A measuring device and transversely moveable knife blade are attached at the wind up station. A cylindrical core is provided with a pivotal edge clamp for the material to be wound. When latched in the clamping position a support wire holds the inside turn away from the core surface. When the clamp is released, the support wire folds down to reduce the diameter of the core and allow it to be pulled from inside the formed roll. |
