Abstract
The invention relates to an address printing machine having a flat printing pad, a printing anvil, and two driving systems. The printing anvil serves as a support for a data carrier with raised characters and for a printing assembly having at least one sheet of paper and an interspaced ink transferring ribbon (carbon paper). One of the driving systems serves to move the printing pad or printing anvil into the operating position, with a minimum of power and the other driving system subsequently causes an electromagnetic impulse printing device to exert a very short impression impulse to achieve the ink transfer with a minimum of movement.
Claims23
An address printing machine comprising:
- a central frame, a swivel arm pivotally mounted to said central frame, a printing pad mounted on said swivel arm, a printing anvil mounted on said central frame and slidable in a direction toward and away from said printing pad, said printing pad being movable toward and away from said printing anvil upon the pivoting of said swivel arm, an electromagnetic impulse printing device supported by said central frame and connected to said printing anvil to move said printing anvil toward said printing pad when enabled, a locking mechanism connected between said swivel arm and said central frame, said locking mechanism including a locking pin connected to said swivel arm and a locking lever having a groove pivotally connected to said central frame, said locking pin being receivable within said groove when said swivel arm is pivoted to move said printing pad toward said printing anvil to interlock said locking pin within said locking lever groove so as to define the locking position of said locking mechanism and the printing position of said printing pad, and an unlocking lever pivotally mounted on said swivel arm and engageable with said locking lever, first spring means connected to said swivel arm and said unlocking lever, said first spring means urging said unlocking lever against said locking lever to urge said locking lever away from said locking pin upon said swivel arm being pivoted to move said printing pad away from its printing position, and means for enabling said electromagnetic impulse printing device after said printing pad has been placed in its printing position to move said printing anvil toward and into contact with printing pad.
