Abstract

The printing machine has solenoid-operated needles, the printing surface being cylindrical (23). The needles (111-113) arranged radially round this surface. Their corresponding solenoids can be arranged in a spiral pattern and in one or two rows. Where the needles are assembled together into heads, the needles in each head can have their printing tips in a line parallel to the cylinder axis, the heads being offset from each other so that their needles print a continuous line across a sheet at right angles to its direction of movement. The heads are of circular cross-section.
