More Information
Summary:An industrial process recording instrument includes a roll chart cassette assembly that is readily removable from the instrument to accommodate replacement of the chart record. The replacement chart record is furnished on a supply roll insertable in one place of the cassette, while the lead end of the chart record is fixedly presecured to a take-up roll insertable in another place of the cassette, in such disposition that the longitudinal axis of the chart record is exactly perpendicular to the axis of the take-up roll. Thus the roll chart can be easily installed while the cassette is being hand-held in near-perfect alignment, thereby effectively minimizing the possibility of paper jams as the chart record is fed along the cassette.
