  • Registration system with independent laterally adjustable nips
    Patent number: 10556765
    Abstract: A registration system for a printing device and a method for controlling the same are disclosed. For example, the registration system includes at least one sensor to detect a position of a print media, at least one laterally adjustable nip, wherein the laterally adjustable nip moves along an inboard direction and an outboard direction, a motor coupled to the at least one laterally adjustable nip to move the at least one laterally adjustable nip a desired amount of movement based on the position of the print media and a width of the print media, and a processor communicatively coupled to the at least one sensor and the motor to calculate a desired amount of movement based on the position of the print media and control the motor to move the at least one laterally adjustable nip by the desired amount of movement.

  • Spreader system having pressure roll and method for controlling pressure in a pressure roll
    Patent number: 9138983
    Abstract: A method and system for controlling a crown height associated with a nip profile includes adjusting pressure of a pressure roll. This may influence the shape of the pressure roll which may influence the nip profile. This may help prevent wrinkling and extend the life of the pressure roll. The pressure roll may be configured to have a varying wall thickness across a width of the pressure roll. The pressure roll may be used for a web application.
