Abstract
In an apparatus for applying ink patterns on oriented strand boards, the boards are serially moved closely adjacent to and past ink jets, and ink is deposited on the boards. To deposit the ink accurately on the boards they are advanced by pinch and drive rollers which also ensure that the boards are flat as they move past the jets. Detectors are used to detect boards which cannot be flattened or are irregular in shape and in such a case the ink jets are moved to avoid impact by an irregular board. During printing, the panels and the ink jets are about 0.0625 inches to about 0.125 inches apart, and the panels are moved at a rate of about 150 ft/minute to 600 ft/minute.
Claims12
An apparatus for applying ink patterns on boards, comprising:
- means for serially moving the boards in a selected direction and through a predetermined space;
- means for applying ink, said means for applying ink being movable from a first position adjacent the predetermined station to a second position remote from the predetermined space;
- means for detecting boards moving in the selected direction and having a part thereof outside the predetermined space;
- means responsive to the detecting means for moving the means for applying from the first position into to the second position when a board traveling in the selected direction is outside the predetermined space, whereby contact between moving boards and said means for applying ink is avoided;
- and
- means for controlling the means for applying ink to apply the ink pattern on the boards traveling within the predetermined space.
