Abstract
A system for containment of particulate matter during operation of a Blow/Fill/Seal packaging machine which generates a particulate matter entraining air flow between extruded parisons and an adjacent suction chamber.
Claims7
A particulate matter containment system for a Blow/Fill/Seal packaging machine which comprises
- a suction chamber mountable to said Blow/Fill/Seal packaging machine adjacent to a parison extruder head and provided with at least one exhaust port;
- and
- at least one suction intake duct in confined flow communication with the suction chamber and defining an intake slot adjacent to the parison extruder head.
The particulate matter containment system according to claim I wherein the suction chamber is shaped as a rectangular prism and wherein the suction intake duct is inclined downwardly from the suction chamber.
A method of reducing particulate matter at an extruder head of a Blow/Fill/Seal packaging machine which comprises inducing a particulate matter entraining air flow at extruded parisons by generating a negative pressure differential of at least 0.02 pounds per square inch at an intake slot of an adjacent suction chamber.
