ABSTRACT:
A progressive plotter for working on successive segments of an elongated web of sheet material extending across a work surface has a pen supported to move in marking relation to material on the work surface in response to command signals received from a programmable controller. The machine includes a supply roll for paying-off sheet material and a take-up roll for receiving material from the supply roll. Each roll has a cylindrical tubular cardboard roll core extending throughout its axial length. The rolls are supported by flanged hub assemblies, each including a cylindrical hub member having a rough generally cylindrical peripheral surface and a diameter smaller than the inside diameter of the smallest roll core to be supported by the machine. The hub members rotate in rolling engagement with the inner peripheral surfaces of the roll cores to drive and/or support the rolls. Each hub assembly has an axially inwardly open recess defined by the hub member and its associated flange for receiving an end portion of a roll core which extends beyond the radially disposed end face of the sheet material wound thereon.
