摘要： An improved applicator die for alternately depositing different liquid coating materials on a moving web comprises a die body having switch bars for opening and closing respective flow passageways for supplying the different liquid coating materials to an elongated coating orifice from respective manifolds. The switch bars, flow passageways and manifolds are substantially as wide as and substantially parallel to the coating orifice of the die whereby changeover between different coating materials can be made very rapidly.

摘要： An improved method for forming a multilayer sheet or multilayer film and an improved forming die apparatus, include making the thickness of the multilayer sheet or multilayer film uniform along the width. In the forming die apparatus, an elastic choke bar is disposed in a passage of the melted resin along the width of the passage. A plurality of bolt members are arranged to abut against the choke bar. The choke bar is pushed and pulled by each bolt member, and a part of the choke bar corresponding to the bolt member is bent with regard to the passage. Thereby, the clearance along the width of the passage can be adjusted for every bolt member.

摘要： An extrusion apparatus and method for producing a composite profile strip characterized by an extrusion head having plural flow channels extending to an extrusion die and at least two extruders for feeding respective components at respective different pressures into the flow channels for passage to the extrusion die. The extrusion die has a common die outlet from which the components are discharged to form the composite profile strip, and respective flow restriction devices are disposed in the flow channels between the extruders and the extrusion die. The flow restriction devices are operative to decrease the difference in pressure between the components before being brought together at the extrusion the extrusion die and further to dampen the effect changes in extruder speed has on the profile of the composite profile strip.

摘要： The present invention relates to novel multi-layer coextruded thermoplastic stretch wrap films useful for the packaging or palletizing of goods. More particularly the films of this invention comprise at least three layers having two outer layers and at least one intermediate layer placed between the outer layers. The intermediate layer is formed from a high pressure low density polyethylene resin and the outer layers are formed from a linear low density polyethylene copolymer such as ethylene copolymerized with a minor amount of at least one C.sub.4 to C.sub.10 alpha-olefin, such as hexene-1, octene-1, decene-1, 4-methyl-pentene-1 and butene-1. The force required to stretch the novel films of this invention may be controlled by the thickness of the intermediate layer relative to overall film thickness, the melt index of the intermediate layer resin, the molecular weight of the intermediate layer resin or a combination thereof.

摘要： A process and apparatus for the coextrusion of a multilayer polymeric body is provided which incorporates protective boundary layers into the body, protecting the layers from instability and breakup during layer formation and multiplication. The process includes the steps of providing at least first and second streams of heat plastified extrudable thermoplastic material which are combined to form a composite stream having the first substreams and second substreams interdigitated. A third stream of heat plastified thermoplastic material is supplied to the exterior surfaces of the composite stream to form protective boundary layers adjacent the walls of the coextrusion apparatus through which the heat plastified polymer streams pass. Layer instability and breakup are avoided using process conditions which would otherwise adversely affect the optical and/or mechanical properties of the articles which are formed.
