Patent number: 4420510Abstract: A method of uniformly applying a foamed adhesive to a normally moving substrate which is subject to stops and starts at irregular intervals. A uniform spread weight of adhesive is applied during a deceleration period and startups can be accomplished without causing puddles or gaps. The method is especially useful in conjunction with an automated plywood lay-up line. Foamed adhesive is supplied under pressure to an extrusion head. When a line stoppage is sensed a first valve above the extrusion head closes. Adhesive within the head continues to expand and fall onto the substrate, but does so at a descreasing rate during the deceleration time. As the substrate comes to a complete stop a second valve prevents further adhesive from being applied. Before a startup, the adhesive in the system is reconditioned by passing it into a recycle line until foam quality andpressure drop across the extrusion head have again assumed normal operating parameters. Only then is the substrate movement started.Type: GrantFiled: March 23, 1982Date of Patent: December 13, 1983Assignee: Weyerhaeuser CompanyInventors: Arden L. Kunkel, Darrell E. Pierson

Patent number: 4374871Abstract: During the axial shirring of tubular casings into shirred strands while the material is inflated with air under overpressure, oil is intermittently injected without propellant air against the inside of the casing, so as to lubricate the inner wall of the casing. This eliminates the need for the costly construction required to provide for the discharge of excess air and oil needed with the known continuous oil injection through two-component nozzle with propellant air, and at the same time it insures a more uniform distribution of oil with reduced oil consumption. The injection nozzle is a single compound nozzle which is connected via electromagnetic valves to a conventional injection pump.Type: GrantFiled: June 1, 1981Date of Patent: February 22, 1983Assignee: Gunter KollrossInventor: Fritz K.
