摘要:
An improved mechanism for properly aligning a rotatable indicia carrying member and for locking said rotatable indicia carrying member in place. Both the aligning and locking mechanisms are formed as integral parts of a single frame unit and are operative to perform their respective aligning and locking functions during movement of the frame unit into engagement with the rotatable member.

An apparatus and method for microcontact printing are described. The microcontact printing apparatus includes a planar stamp and a pressurized roller. The pressurized roller includes an inflatable bladder that can be inflated by a fluid to a pressure that reduces printing defects such as voids and stamp collapse. A substrate is disposed between the pressurized roller and a stamp coated with an ink of functionalizing molecules. As the pressurized roller moves over the substrate, at least a portion of the functionalizing molecules are transferred from the stamp to the substrate in the desired pattern.

The invention relates to a method for stamping information carriers, in particular, card-shaped carriers, such as credit cards, identification cards, customer cards, bank cards and the like by means of two type carriers. One type carrier holds raised type and the other type carrier holds recessed type in the form of numbers and letters. The type carriers stamp the desired characters into the material of the information carrier held between the two type carriers. In the inventive method, multiple characters of at least one line are simultaneously stamped in a single stamping process. All characters in a line thereby can be stamped in a single stamping process or successively in successive stamping processes.

A strip of label material is fed from a supply roll to a preprint unit which incorporates a set of strip feed rolls driven by an electric motor-reducer drive unit. The drive unit is adapted to be stopped by a rotary solenoid actuated brake controlled by a photocell which senses the advancement of the strip. A print drum is rotatably supported above the generally horizontal path of the strip and has peripherally spaced axially extending rows of printing characters. A set of hammer members are positioned under the print drum and are selectively actuated by a corresponding set of solenoids. The print drum is indexed at a high speed by an electric stepping motor which automatically returns to a start position, and the printing characters are inked by a ribbon which is advanced by another electric motor-reducer drive unit pivotally supported to provide for automatically reversing the feed direction of the ribbon. A post-print unit includes a solenoid actuated rotary cutter which is positioned in the path of the strip for shearing each label from the strip, and each label is printed by a rotary print cylinder which carries an axially removable peripheral print key and encloses a plurality of individually adjustable endless flexible printing bands. The print cylinder is driven through a friction clutch by another electric motor-reducer drive unit, and a releasable latch positively stops the print cylinder after each revolution.
