Document Type and Number:
Japanese Patent JP2880957
Kind Code:
B2
Abstract:
A progressive plotter (10) for working on successive segments of an elongated web of sheet material (P) extending across a work surface (14) has a pen (24) supported to move in marking relation to material (P) on the work surface (14) in response to command signals received from a programmable controller. The machine includes a supply roll (20) for paying-off sheet material (P) and a take-up roll (22) for receiving material (P) from the supply roll (20). Each roll (20,22) has a cylindrical tubular cardboard roll core (C) extending throughout its axial length. The rolls (20,22) are supported by flanged hub assemblies (12), each including a cylindrical hub member (48) having a rough generally cylindrical peripheral surface (54) and a diameter smaller than the inside diameter of the smallest roll core (C) to be supported by the machine. The hub members (48) rotate in rolling engagement with the inner peripheral surfaces of the roll cores (C) to drive and/or support the rolls (20,22). Each hub assembly (12) has an axially inwardly open recess (60) defined by the hub member (48) and its associated flange (50) for receiving an end portion of a roll core (C) which extends beyond the radially disposed end face of the sheet material (P) wound thereon.
