Abstract
A glue machine for a corrugator single facer utilizes a system of simultaneously operated linear actuators to move the glue machine from an idle position adjacent the single facer to a locked position on the single facer, and then to a running position with the glue machine glue roll in a pre-established position with respect to a corrugating roll on the single facer. The glue machine is carried on laterally spaced pairs of front wheels and rear wheels mounted on pivot arms. The linear actuators are preferably air cylinders interconnecting front and rear wheel pivot arms to provide sequential glue machine frame movement from the idle to the locked position, followed by movement to the running position.

An apparatus for positioning and locking a glue roll supported on the frame of the glue machine and moving the glue roll into operative position with respect to a corrugating roll supported on the frame of a single facer machine, said apparatus comprising:
- a pair of laterally spaced front wheels attached to and supporting the glue machine frame on a rotatable front pivot arm;
- a pair of laterally spaced rear wheels attached to and supporting the glue machine frame on a rotatable rear pivot arm;
- and,
- an actuator device connecting said front and rear pivot arms and operable to initially rotate the front pivot arm to move the front wheels from an idle position supporting the front of the glue machine frame on a horizontal support surface to a locked position with the front wheels lifted from the horizontal surface and the front of the glue machine frame lowered vertically into a pivotal position on laterally spaced supports defining a common axis on the single facer machine frame and the glue machine frame and, said actuator device operable thereafter to rotate the rear pivot arm and move the rear wheels over the horizontal surface to rotate the glue machine frame about the axis of the supports from the locked position to a running position defined by a glue machine frame abutment surface in contact with a single facer machine abutment surface.
A method for positioning and locking a glue roll supported on the frame of a glue machine and for moving the glue roll into operative position with respect to a corrugating roll supported on the frame of a single facer machine, said method comprising the steps of:
- (1) supporting the glue machine on pairs of laterally spaced front wheels and rear wheels attached to the glue machine frame by respective pairs of rotatable front and rear pivot arms;
- (2) connecting the front and rear pivot arms with a linear actuator;
- (3) operating the actuator to initially rotate the front pivot arms and move the front wheels from an idle position supporting the front of the glue machine frame on a horizontal surface to a locked position with the front wheels lifted from the horizontal surface and the front of the glue machine frame lowered vertically onto laterally spaced support blocks on the single facer machine frame;
- and,
- (4) continuing operating the actuator to rotate the rear pivot arms and move the rear wheels over the horizontal surface to rotate the glue machine on the support blocks from the locked position to a running position with a glue machine frame abutment surface in contact with a single facer machine abutment surface.
