PROCESS FOR GUIDING A SHEET OF PAPER IN A COLOUR-TAPE CASSETTE, AND A COLOUR-TAPE CASSETTE FOR CARRYING OUT THE PROCESS

摘要

If several successive colour-application operations are to be carried out on a sheet of paper, the sheet is fed from the sheet output point of a pressure-applying element through a sheet feed channel with a curved turn-round zone back to the sheet input point of the pressure-applying element, and a high sheet-positioning precision if necessary, in order to obtain high-quality results. In order to ensure the precise alignment of the repeatedly refed sheet (11), the invention calls for the sheet (11) to be guided, by means of a raised area (60) on the concave surface (42) of the sheet turn-round zone (35), so that it is tilted in stages at right angles to the direction of motion. Downstream of the raised area (60), a force is exerted on the sheet at right angles to the direction of motion of the sheet, the force aligning the sheet (11) with the edge of a sheet-guidance surface (100).
