Abstract:
A fluid application device having a flow diverter is provided. The fluid application device includes an applicator head having an internally formed manifold having a fluid input conduit, two or more fluid output conduits and a chamber disposed between the input conduit and the two or more output conduits. An external attachment surface is formed on the applicator head and is configured to have two or more nozzles selectively and removably secured thereto. A flow diverter is removably disposed in the chamber and includes a plug having two or more channels, each channel in fluid communication with the fluid input conduit and a respective fluid output conduit of the two or more output conduits. The fluid input conduit is configured to receive a fluid from a supply source and the two or more fluid output conduits are configured to discharge the fluid from the applicator head to respective nozzles.
Abstract:
A modular system for delivering a fluid material is provided that may include a supply assembly for supplying a fluid material, a rate controlling assembly, and a pressure controlling assembly. The rate controlling assembly may be in fluid communication with the supply assembly and may vary a rate of a first portion of the fluid material supplied to a first applicator. The pressure controlling assembly may be in fluid communication with the supply assembly and may vary a pressure of a second portion of the fluid material supplied to a second applicator.
Abstract:
An extruder assembly may include an entry die, an exit die, and one or more shims. The exit die can be coupled with a fluid applicator system with the entry die facing away from a body of the system to direct adhesive flowing into the exit die, through the shims, and out of the exit die, the entry die, and the shims onto a web or strand moving in a first direction. The entry die may be coupled with the body of the system with the exit die facing away from the body to direct the adhesive onto a web or strand moving in a second, opposite direction.
Abstract:
