| titleOfInvention | Extrusion die deckle |
| abstract | 1,048,450. Extrusion dies. FRANK W. EGAN & CO. Aug. 17, 1964 [May 4, 1964], No. 33464/64. Headings B5A and B5B. A film or sheet-forming die having an elongated slot formed between two jaws, at least one of which is adjustable towards and away from the other to vary the width of the slot, is provided with a deckle-bar having a sealing face bridging the slot and in slidable sealing contact with bearing surfaces provided on each jaw and each extending outwardly from and along one side edge of the slot, and means mounting the deckle-bar on the die for movement of the bar longitudinally of the slot. A deckle-bar carrier holds the deckle-bar in sealing contact with the bearing surfaces on the jaws, while providing for movement of at least one jaw relative to the carrier to adjust the width of the slot. The die may be used for film casting, laminating or extrusion coating using, e.g. polyethylene. In one embodiment (Figs. 1, 2 and 3, not shown), a die for extrusion laminating consists of a body 2 containing manifold hole 3 communicating by passage 5 with slot orifice 10 formed between jaws 6 and 7. Jaw 6 is fixed in position by bolts 8<SP>1</SP>, while jaw 7 is movable towards or away from jaw 6 by means of adjusting screws 8, a clearance being provided between jaw 7 and retaining bolt 9. Electric heaters 11 are fixed to the die body by clamps 12. The die body also carries heaters 13. End caps 14 seal the ends of the slot orifice 10. Each deckling means 15, provided at each end of the die, consists of a deckle-bar 24 held against flat surfaces 10a of jaws 6 and 7 by set screws 25 provided in a U-shaped deckle-bar carrier 16. The carrier is supported by hanger rail portions 16a bearing on track portions 6a, 7a of jaws 6 and 7. The deckle-bar, and the carrier, are moved slidably along the die jaws by turning pinion wheel 18, which engages in gear teeth 17 on the carrier 16. The deckle-bar 24 is faced with a heatresistant layer 23 of graphite-impregnated asbestos or fluorocarbon plastic, which allows the bar to slide along the jaws while providing sealing contact. The width of the extruded film may thus be varied without alteration of the die jaw setting. The entire deckle-mechanism may be removed by rotating pinion 18 until it is disengaged from teeth 17. |
