ABSTRACT:
A machine for rolling an article, such as a rain gutter, from sheet metal dispensed from a coil comprises an elongate base having an input end, at which sheet metal dispensed from a coil is inputted into the machine, and an outlet end, at which an article rolled by the machine is outputted from the machine. An elongate track mounted on the machine and extending between those ends includes a pair of rails extending between those ends. A dispenser for mounting a coil of sheet metal and for dispensing sheet metal from the mounted coil into the machine at the input end is supported on the elongate track, via two dispenser-supporting rollers engaging each rail, so that the dispenser can be selectively positioned on the elongate track in a loading position, near the input end of the elongate base or in a dispensing position, near the output end of the elongate base. The dispenser can be releasably secured in the dispensing position. The dispenser includes a pair of coil-supporting rollers for supporting such a coil and for enabling the supported coil to rotate about a horizontal axis defined by the coil as a strip of sheet metal is dispensed from the supported coil. A biasing roller is adapted to extend through the supported coil and is biased gravitationally for biasing a supported coil downwardly against the coil-supporting rollers.
