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: A piston monitoring assembly includes a magnetic body coupled to a piston that is configured to move in opposite directions during a piston stroke to dispense a fluid, a magnetic sensor configured to output signals representative of a magnetic field generated by the magnetic body, and a controller configured to examine the signals output by the magnetic sensor and to determine whether the piston is moving far enough to ensure that the fluid is being dispensed during a first movement of the piston in the piston stroke and that the fluid is prevented from being dispensed during a second movement of the piston in the piston stroke.
