Abstract

The impression (pressure) control for a paper sheet 1 in a printer consists of a flexible steel band 10 like a steel tape measure, having a disked or slightly curved cross-section as shown in Fig. 2. The convex aide of the band 10 is disposed next to the paper, the band being rolled up on a spool 12 at one side of the printer and attached to the movable head 14 as shown in Fig. 1, so that the band 10 rolls up and unrolls along the print line as the head 14 moves in opposite directions across the paper. An opening 16 in the band at the head 14 permits printing through the band, or the band 10 may be secured to the print head on the side toward the spool 12.

Pressure Device for a Printer with a Movable Print Head

The impression (pressure) control for a paper sheet 1 in a printer consists of a flexible steel band 10 like a steel tape measure, having a disked or slightly curved cross-section as shown in Fig. 2. The convex aide of the band 10 is disposed next to the paper, the band being rolled up on a spool 12 at one side of the printer and attached to the movable head 14 as shown in Fig. 1, so that the band 10 rolls up and unrolls along the print line as the head 14 moves in opposite directions across the paper. An opening 16 in the band at the head 14 permits printing through the band, or the band 10 may be secured to the print head on the side toward the spool 12.

In another form as shown in Fig. 3, the band 10 may be in two sections wound onto spools 12 at opposite ends of the printer. In both cases, the band 10 presses against the paper 1 holding it at all times firmly in place against the platen 18.
