Hand-held labeling machine has control to ensure inking roller rolls-off printing type and roller contact pressure is determined by spring torque only

摘要

The machine has an inking roller with a device to move it out of movement range of the printer. The device is formed by a surface of the rocker arm, to which the printer is fastened . The surfaces engage with a surface on the rocker arm, after the printer has moved along a first distance. The machine (1) has an inking roller (19) with a device to move it out of movement range of the printer (15). The device is formed by a surface of the rocker arm (14), to which the printer is fastened . The surfaces engage with a surface on the rocker arm, after the printer has moved along a first distance. The surface on the rocker arm is located closer to the pivot bearing (21) of the rocker arm than the inking roller. Due to this, the roller is moved at a speed, which is higher than the relative speed between the two engaging surfaces.
