Abstract
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 bar can be hooked onto the support hooks to receive a roll of the floor covering. The bar can be lifted into place by a lift mechanism in the form of an elongate bar with an upper and lower hook so the upper hook can engage over a previous bar and a lower hook can lift the intended bar to a position adjacent its receiving hook. An overcenter linkage then is used to reduce the length of the bar to lift the new bar into engagement with its respective hook. 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of stub rollers one of which is rotated by a hand crank and expandable thereby to engage a tube and wind up material withdrawn from one of the rolls.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.
