Abstract
A metering rod assembly including a body for accommodating a metering rod insert and configured to clamp the metering rod and/or metering rod insert without the use of an auxiliary clamping device, such as a pressure tube or the like. A rod bed insert is supported in a tapered channel of a body whereby a clamping action is created during use. In another embodiment, the body includes a hinge portion that facilitates relative rotation between upper and lower jaws to create a clamping action during use.
Claims12
A metering rod holder assembly for supporting a metering rod in compressive engagement with an associated roller of a paper machine, the assembly comprising:
- a base member mountable to a support, the base member having a tapered channel opening to a first face thereof, the tapered channel having a base portion and first and second side walls extending from the base portion and spaced about a central plane of the channel, the first and second side walls extending at non-zero angles relative to the central plane;
- and
- a replaceable rod bed insert at least partially received in the channel of the base member, the rod bed insert having a metering rod slot for receiving a metering rod, the rod bed insert including first and second side walls in abutting engagement with the first and second side walls of the base member;
- wherein the rod bed insert is spaced apart from a base portion of the channel;
- whereby, when a metering rod is installed in the metering rod slot, a force applied by an associated pressure tube parallel to the central plane placing the metering rod in compressive engagement with the associated roller urges said side walls of the rod bed insert towards each other thereby clamping the metering rod in the channel of the base member;
- and
- wherein the rod bed insert is configured to be closely received in the channel, first and second side walls of the insert having a mating shape to the first and second side walls of the channel, the rod bed insert having spaced parallel longitudinally disposed slots to facilitate flexing of the rod bed insert.

- and
- a pressure tube for applying the force to the base member;
- wherein the rod bed insert is spaced apart from a base portion of the channel;
- and
- wherein the rod bed insert includes spaced parallel longitudinally extending slots to facilitate flexing of the rod bed insert, the longitudinally extending slots extending in a common direction along a length of the channel;
- whereby, when a metering rod is installed in the metering rod slot, a force applied by an associated pressure tube parallel to the central plane placing the metering rod in compressive engagement with the associated roller urges said side walls of the rod bed insert towards each other thereby clamping the metering rod in the channel of the base member.
