Abstract
A pan and an applicator roller supported thereby are pivotably supported for movement between operative and inoperative positions by a parallelogram link means including a gear segment. Actuator means is connected to the gear segment for rotating the same in opposite directions.
Claims15
A mechanism for applying a liquid to a moving web comprising a pan for containing a supply of the liquid, a support structure pivotably supporting said pan by a parallelogram link means on opposite ends of the pan for movement between operative and inoperative positions, each of said link means including a discrete segment gear and a link, and actuator means including a shaft below the elevation of said mechanism, a pair of pinions on said shaft for rotation therewith, each pinion being meshed with a discrete segment gear on opposite ends of the pan for simultaneously rotating said discrete segment gears to thereby move said pan between its operative and inoperative positions.
In a single facer machine having a pair of meshed corrugated rolls and a pressure roll juxtaposed to one of the corrugating rolls, a mechanism including an applicator roll for applying an adhesive bonding agent to the crests of fluted medium on one of said pair of corrugating rolls, said mechanism including a pan supporting said applicator roll and mounted for movement therewith between operative and inoperative positions, the improvement comprising a parallelogram link means on opposite ends of the pan, each of said link means including a link and a discrete segment gear, and actuator means coupled to each discrete segment gear for rotating the discrete segment gears simultaneously to thereby move the glue mechanism between its operative and inoperative positions.
A mechanism for applying a liquid to a moving web comprising:
- a pan for containing a supply of the liquid;
- a support structure pivotably supporting said pan by a pair of parallelogram link means on opposite ends of said pan for movement between operative and inoperative positions, each of said link means including a discrete segment gear;
- actuator means coupled to each of said segment gears for simultaneously rotating each of said segment gears to thereby move said pan between operative and inoperative positions;
- and
- said actuator means including a hydraulic circuit having a counterbalance valve sensitive to forces on said mechanism above a predetermined amount for dumping pressurized hydraulic liquid to a reservoir when said mechanism is subjected to forces above the predetermined amount.
