  • Apparatus and method for monitoring the moisture gradient in a moving web
    Patent number: 3981082
    Abstract: Apparatus and method are disclosed for detecting the moisture gradient in a moving web. A radio frequency signal is applied to a transmitting means which transmits an electromagnetic field through the web being sensed. The moisture gradient of the web is monitored by sensing a control signal which is indicative of fluctuations in the strength of the transmitted electromagnetic field owing to the absorption of energy by moisture on the web moved through the field.

  • Corrugator
    Patent number: 3977929
    Abstract: The separate machines of a corrugator are coupled so that they can be operated in synchronization. The separate machines are controlled as a unit by use of tachometer feedback signals which eliminate motor speed drift and permit operation at relatively high speed during an order change.

  • Dual ink circulation and wash-up system for a press
    Patent number: 3974768
    Abstract: A printing press is provided with a dual ink circulation and wash-up system to reduce the wash-up time between color changes. The press includes a fountain and at least one receptacle associated therewith and having at least two compartments. Means are provided to selectively divert liquid from the fountain into one of the compartments while the other compartment is being washed. A plurality of ink supply means are provided for sequentially supplying ink to the fountain.

  • Paperboard corrugator
    Patent number: 3966518
    Abstract: Method and apparatus are disclosed for monitoring the quantity of single face paperboard on the bridge of a corrugator so that a unit length of paperboard will remain on the bridge for a preselected time irrespective of the speed of the corrugator to properly season the paperboard. Signals indicative of input and output of paperboard to the bridge are compared with a signal indicative of a preselected time and a signal is generated to effect changes in the single facer machine motor speed.

  • Cutoff mechanism
    Patent number: 3962942
    Abstract: The cutoff mechanism repetitively cuts a moving web into sheets by at least one cutting blade movable in the direction of travel of the web at web speed at the instant of cutting. The cutting blade is controlled by a cyclic mechanism. The cyclic mechanism has a uniform input speed or a cyclic input speed. When the cyclic mechanism is driven with a cyclic input speed, the normal range of sheet length is doubled.

  • Apparatus having a quick-set slotter knife
    Patent number: 3954050
    Abstract: Apparatus such as a paperboard printer slotter is provided with a device to quickly reposition a slotter knife by moving the same in a circumferential direction with respect to an annular head which supports the same. During such positioning of the slotter knife, it is held stationary while the annular support head is rotated. This slotter knife is releaseably mounted on its head and a means is provided to selectively release the lock when it is desired to reposition the knife.

  • Preheater and method of controlling wrap of a web
    Patent number: 3946800
    Abstract: The amount of wrap between a web and a heated drum is varied as a function of web speed by adjusting the position of idler rollers in response to a reference speed signal.
