Patent number: 9744791Abstract: A booklet processing mechanism is described that includes a spine guidance system that is configured to hold the area adjacent to the spine of an opened, multiple sheet booklet against a backing plate during processing on a page of the booklet, for example by a laser or during vision verification. The spine guidance system is configured so that it resides closely adjacent to the spine of the booklet, below the field of lasing by the laser or other processing operation, so that it does not interfere with the processing operation.Type: GrantFiled: August 23, 2013Date of Patent: August 29, 2017Assignee: ENTRUST DATACARD CORPORATIONInventors: Gary Schultze, Dennis J.

Patent number: 9346308Abstract: A booklet processing mechanism is described that includes a booklet guide and clamp system that is configured to act as the guide during entry and exit of the booklet into and from the mechanism, as well as clamp and hold the booklet in its proper position during a processing operation, for example by a laser or during vision verification. The booklet guide and clamp system is moveable between a first position for guiding an upper, free edge of an opened booklet and a second position where the upper, free edge is clamped against a backing plate. At the second, clamping position, the mechanism is out of the way so that it does not interfere with the processing operation. Because the guiding and clamping functions are combined into one mechanism, only one actuator and one sensor are needed for the guiding and clamping functions.Type: GrantFiled: August 23, 2013Date of Patent: May 24, 2016Assignee: ENTRUST DATACARD CORPORATIONInventors: Michael Lind, Gary Schultze, Dennis J.

Patent number: 7441970Abstract: Identity document processing equipment with a mechanism designed to maintain tension in a ribbon used in a processing operation in the processing equipment. The tension maintaining mechanism is separate from the supply roll and the take-up roll for the ribbon, eliminating the need for clutches or brakes attached to the supply or take-up rolls to achieve tensioning. Since the tension maintaining mechanism is separate from the supply roll and the take-up roll, the inertia of the supply roll or the take-up roll does not affect the tension on the ribbon during use of the processing equipment.Type: GrantFiled: November 10, 2005Date of Patent: October 28, 2008Assignee: DataCard CorporationInventors: Milo B Squires, Dennis J. Warwick, Richard C. Nubson

Patent number: 5588763Abstract: A magnetically encoded plastic card production system is provided which includes a supply mechanism for supplying a series of blank plastic cards. An encoder is operatively coupled to the supply mechanism which encodes a magnetic strip on each card. A separating mechanism is operatively coupled following the encoder which has a roller surface for adhesively attracting loose particles from a surface of each card. A design placing mechanism is operatively coupled immediately following the separating mechanism which places a graphic design on each card. In this arrangement, the loose particles are separated from each card subsequent to encoding the magnetic strip on each card and prior to placing the graphic design on each card. A collecting mechanism is operatively coupled to the design placing mechanism which collects each card after each card has passed through the encoder, separating mechanism, and design placing mechanism. A method for producing magnetically encoded plastic cards is also provided.Type: GrantFiled: October 18, 1994Date of Patent: December 31, 1996Assignee: Datacard CorporationInventors: Richard C.

Patent number: 5453821Abstract: A method and apparatus for a two-pulse solenoid embossing system implementing an amplitude feedback circuit, i.e., current monitor (48), to provide precise amplitude and timing control over two current pulses (4, 5), and thereby provide precision control over the position and velocity of the embossing system's print elements (64a, 64b). To maintain the current amplitude during the second current pulse (5), the method and apparatus alternatively switches the power on and off to the solenoid coils (55) with a frequency such that a substantially constant current amplitude is maintained in the solenoid coils (55). The embossing system provides an improved solenoid body assembly (61) including a first stack of steel laminations (93), a center block (82) and a second stack of steel laminations (81). A plunger (62) is slidably connected to the solenoid body assembly (61) by shaft (63). Cavities (79) receive dowel pins (71) which are attached to plunger (62).Type: GrantFiled: December 10, 1992Date of Patent: September 26, 1995Assignee: DataCard CorporationInventors: Ronald B.

Patent number: 5401111Abstract: An apparatus and method are described for removing particulate matter from one or more surfaces of a workpiece, such as a credit card blank, prior to printing a graphic design thereon. The apparatus includes a pair of cleaning rollers which engage both sides of the card, the cleaning rollers having an adhesive coating for removing loose particulate matter from the surfaces of the card. The apparatus also includes a stripper system for stripping collected particulate matter away from the cleaning rollers after a predetermined number of cards have been cleaned.Type: GrantFiled: February 17, 1993Date of Patent: March 28, 1995Assignee: DataCard CorporationInventors: Richard C.

Patent number: 5320435Abstract: An apparatus for embossing sheet material by applying pressure to punch and die members positioned on both sides of the sheet material using force developed by one or more solenoids to force the punch and die members together to apply an imprinting force. In order to reduce the impact force, noise and wear on the mechanical parts, the solenoid may be energized in two separate steps, the first to move the punch and die members into contact with the surface of the card and the second to apply the embossing force to the punch and die members. Both rotary and linear solenoids may be used with differing coupling linkages in various embodiments of the embossing mechanism.Type: GrantFiled: September 22, 1992Date of Patent: June 14, 1994Assignee: DataCard CorporationInventors: Dennis J. Warwick, Ronald B. Howes, Jr.

Patent number: 5266781Abstract: Standardized card processing modules are mechanically and electrically interconnected to form an application specific card personalization machine. A controller is coupled to a communication bus which permits the controller to download card data to the card processing modules and to upload status information from the card processing modules. Each one of the card processing modules performs a different encoding or personalization function under the control of a local processor.Type: GrantFiled: August 15, 1991Date of Patent: November 30, 1993Assignee: Datacard CorporationInventors: Dennis J. Warwick, Robert W. Lundstrom, Joseph Zaloker, Gary Mattila, Benjamin H. Sannel, Steven G. Dorfe, Theresa J. McNamara, Jeffrey P. Johnson, Glenn R. Carney, Steven A. Miller

Patent number: 5206489Abstract: An encoding apparatus (20) encodes or reads information on a magnetic stripe on a card (50). The encoding apparatus (20) advances the card (50) along a card transport path defined by a frame (24), side support members (42 and 44), and top guide member (46). The card (50) advances by reversible drive means (26) having a single drive roller (28). Encoding is accomplished by an encoding head (36) in communication with an encoder (22) coupled to an idler roller (34) for encoding by position.Type: GrantFiled: August 13, 1992Date of Patent: April 27, 1993Assignee: Datacard CorporationInventor: Dennis J.

Patent number: 5070781Abstract: An embossing apparatus (22) includes an embossing wheel (28) having a punch side (30) and a die side (32). The embossing wheel (28) has punch blocks (50) and die blocks (52) spaced around its periphery. A card (20) is carried to an embossing position by card transport (24) and aligned by a guide plate (36). The embossing is done by pushing the punch blocks (50) and die blocks (52) against the card (20) by a hammer (42, 42a) driven by a solenoid (38, 38a). Character return plates (46, 46a), located on the outer sides of the embossing wheel (28) engaging the inside of character blocks (35), spring the character blocks (35) and solenoid shaft (40, 40a) back to a home at rest position when the embossing stroke is completed. The solenoids (38, 38a) have bumpers (54, 54a) mounted thereon for controlling the motion of the shaft (40, 40 a).Type: GrantFiled: April 30, 1991Date of Patent: December 10, 1991Assignee: DataCard CorporationInventors: Robert W.
