Abstract: Apparatus for producing intermittent, discrete patterns of coating material onto discrete irregular substrate areas, such as electronic circuit boards, where the patterns have sharp, square leading and trailing edges, as well as side edges. A slot nozzle die has elongated air slots along the slot extrusion opening. In the operation of the apparatus, the air flow is initiated from both air slots prior to the initiation of the coating material flow. Also, the air flow is continued beyond that point in time, when the coating material flow ceases. The delays between the operations of the air flow and the hot melt flow are on the order of micro seconds. Alternatively, the lead and lag air start and stop times on each side of the film of coating material are different to control the exact disposition of the square cut-on and square cut-off coating edge on the circuit board. The air flow carries the film coating material to the circuit board for deposition in discrete areas thereon.

Abstract: Apparatus for producing intermittent, discrete patterns of coating material, such as hot melt adhesive, onto discrete substrates or substrate areas, such as book spines, sift-proof carton flaps and pinch-bottom bags. The adhesive patterns have sharp, square leading and trailing edges, as well as side edges. A slot nozzle die has elongated air slots along the slot extrusion opening. In the operation of the apparatus, the air flow is initiated from both air slots prior to the initiation of the hot melt flow. Also, the air flow is continued beyond that point in time, when the hot melt flow ceases. The delays between the operations of the air flow and the hot melt flow are on the order of micro seconds. Coating weights down to 1 gram per square meter at about 350 meters per minute substrate speed are provided.

Abstract: Apparatus for producing intermittent, discrete patterns of foam coating material, onto discrete substrates or substrate areas, where the patterns have sharp, square leading and trailing edges, as well as side edges. A slot nozzle die has elongated air slots along the slot extrusion opening. Air flow is initiated from both air slots prior to the initiation of the foam flow. Also, the air flow is continued beyond that point in time when the foam flow ceases. The delays between the operations of the air flow and the foam coating flow are on the order of micro seconds. Alternatively, the lead and lag air start and stop times on each side of the foam coating material are different to control the exact disposition of the square cut-on and square cut-off coating edge on the substrate.

Abstract: A slot die for producing a fibrous web of adhesive material includes a segmented shim having a plurality of fingers in said slat dividing adhesive material into a plurality of adhesive streams. The fingers have tapered ends which are flush with or extend slightly beyond the slot nozzle outlet. Separate material streams emanate from the slot nozzle outlet where they merge and are engaged by air flow producing a fibrous web of adhesive material. The adhesive and air flow are started and stopped at intervals to produce discrete fibrous webs having square, sharp leading and trailing edges.

Abstract: Apparatus and methods for producing coatings, such as wax or hot melt adhesive, onto the tops and necks of wine bottles or similar objects. A slot nozzle die has elongated air slots along a vertically oriented slot extrusion opening. A hot melt or wax gun is disposed above the bottle neck to apply a bead of adhesive to the bottle top. In the operation of the apparatus, the air flow is initiated from both air slots prior to the initiation of the hot melt flow and is continued beyond that point in time, when the hot melt flow ceases. The air carries a film of coating material horizontally to the bottle neck. Means are provided for spinning the bottle about its vertical axis. The delays between the operations of the air flow and the coating flow are on the order of micro seconds. The merged coatings are heated to smooth the coating finish to produce a traditional neck seal.

Abstract: A winder for continuously winding a traveling web such as paper onto a large roll with a support roll in contact with the roll being wound such as where the support roll is one or both of a pair of parallel horizontally extending drums with the outer surface of the drum being of rubber with embedded nonextensible annular cords and the surface being supported by a plurality of inflatable chambers along the length of the drum so that the outer surface of the drum deforms with contact with the roll being wound and accommodates irregularities along the length of the roll being wound.

Abstract: Disk screen apparatus and disk assemblies therefore wherein each disk assembly comprises an elongate shaft adapted to be rotatably mounted in the disk screen apparatus. The shaft has elongate indexing and keying structure extending longitudinally along and rigid with the shaft and providing a longitudinally extending and circumferentially facing edge. The edge has a series of longitudinally spaced circumferentially extending indexing and keying notches therein. Annular screen disks are mounted on the shaft and have inner diameter key shoulders engageable in the notches. The keying structure may be raised along a longitudinal area on the cylindrical perimeter of the shaft or recessed along such area. A releasable locking bar is adapted for locking the key shoulders in the notches.

Abstract: A flexible elastic ring having a generally rectangular cross section with radially inner and outer surfaces. A plurality of rigid members are molded in the ring at circumferentially spaced-apart positions and each of the rigid members extends diagonally from an edge at the radially inner surface to an edge at the radially outer surface of the elastic ring. The ring is mounted in a wheel well of the tire rim with the tire bead overlapping the edge at the radially outer surface to hold down the ring and the ends of the rigid members in that edge. The other ends of the rigid members are located in the edge at the radially inner surface of the ring adjacent a radially extending side surface of the ring for resisting deflection of the side surface which abuts a radially extending surface of the wheel well. The rigid members prevent the ring from rotating out of the wheel well in this manner when the ring is subject to centrifugal force during rotation of the wheel on which the rim is mounted.
