Backpressure injection foot

摘要

A backpressure injection foot is provided. The backpressure injection foot includes an injection nozzle for applying an adhesive flowing therethrough onto a planar object having a core structure; and a backpressure foot attached to a distal end of the injection nozzle, wherein the backpressure foot is configured to cover a portion of a plurality of cores disposed within the planar object to facilitate application of the adhesive from a proximal surface of the planar object through to a distal surface of the planar object.
