Abstract
A low pressure blow-off assembly provides converging airflow around a length of material moving through the assembly. The assembly generally includes a body having an interior wall and an exterior wall. The interior wall defines a bore extending through the body for receiving the material through the body, and the exterior wall surrounds the interior wall and defines an air reservoir within the body generally between the exterior wall and interior wall. A cap is configured to be coupled to the body to cover at least part of the air reservoir. The bore includes a generally tapered end and the cap includes a generally tapered inner lip, where the tapered end of the bore and the tapered inner lip of the cap define an opening therebetween for discharging air from the air reservoir through the opening in a generally converging airflow pattern around the material passing through the body.
