摘要： Methods related to coextrusion of heat-sensitive polymer materials. The sensitive melt stream element (12) is encapsulated in a second polymeric melt stream element (16). Transport means (36) is preferably employed between the encapsulating means (20) and the die (42). A third melt stream element (68) is joined to one or both opposing surfaces (70) of the second melt stream element (16) between the encapsulating means (20) and the die (42). In the die (42) the encapsulated melt stream element (12) becomes an interior layer (46) between encapsulating layers (48A, 48B) derived from the second melt stream element (16). The third melt stream element (68) forms layers (72, 74) positioned outwardly of the encapsulating layers (48A, 48B). The positioning, on the interior of the extrudate, of edges (54) of layer (46) is adjusted independently of the combined thicknesses of a layer derived from the third melt stream element (68) and an adjacent layer (48).

摘要： A coextrusion system employs two or more extruders, each with a gear pump at its output connected to a coextrusion die. Different materials are extruded by each extruder. Varying the speed of one or both gear pumps varies the content of the extrudate. The gear pumps permit precise variation of the relative content of the materials extruded by the several extruders lengthwise along the extrudate. A display of a cross sectional dimension of the extrudate along a length of the extrudate permits observation of the lag that occurs between alteration of gear pump speed (or air pressure in the case of tubular or blown sheet extrudates) and the resultant change in dimension, so that a speed correction can be made at the appropriate time to compensate for differing shrinkage and stretching characteristics between the several extruded materials.

摘要： Apparatus for extruding plastic and/or rubber material has a screw extruder, which plasticizes the material and delivers it to a gear pump which develops sufficient pressure for extrusion of the material through an extrusion head. The apparatus is characterized by the fact that the axes of gears of the gear pump and the axis of the screw of the extruder are parallel to one another. The housing of the gear pump has a side opening into which a cylindrical bushing and the screw of the extruder extend so that the material is delivered by the extruder directly to the gear pump as a non-oriented plasticized mass. The extrusion head may be a transverse extrusion head with an axis parallel to the axes of the gear wheels of the gear pump and the axis of the screw of the extruder. A second like extrusion apparatus including a screw extruder and a gear pump may be connected to an opposite side of the extrusion head.

摘要： Apparatus and method for fabricating films, especially films containing vinylidene chloride copolymer, wherein the process is susceptible of continued operation over an extended period of time greater than a few days. The process typically can operate for at least 2 weeks between shut downs for cleaning the die. The apparatus comprises a coextrusion feedblock 20 in combination with an annular extrusion die 10 having a crosshead mandrel 11, and means for conveying the exit stream 24 from the feedblock to the die. The particular apparatus combination especially reduces the rate of carbon buildup in the extrusion apparatus during extrusion of VDC-copolymer, such that the extrusion process can be operated for a longer time between shutdowns for cleaning and maintenance of the die. The invention further includes novel tubular films 32 made with the apparatus and methods of the invention, and packages made from the films. In general, the method of the invention produces tubular films having more layers than the annular extrusion die has annular orifices.

摘要： A die assembly (10) for controlling extrudate profile dimension. The die assembly includes a die block (12) having a feed passage (16) for movably supporting a diverter member (13) within the die block, and first and second die block passages (18, 20). The diverter member (13) includes a diverter passage (32) and first and second feed openings (34, 36) interconnected by the diverter passage. One of the first or second feed openings (34, 36) has a larger diameter than the other of the first or second feed openings. The diverter member (13) is movable with respect to the die block (12) for directing extrudate flow via the diverter passage (32) through the second die block passage (20), to thereby vary the profile dimension of the extrudate exiting the die block. The die block (12) additionally includes a disposal passage (22). Movement of the diverter member (13) within the die block is provided between a first position providing communication between the first and second die block passages ( 18, 20), and a second position providing communication between the first die block passage (18) and the disposal passage (22). A die plate (14) may be readily changed by directing extrudate flow via the disposal passage (22).

摘要： A method of producing a multicomponent extrudate in which the operating line automatically and accurately extrudes the extrudate materials necessary to obtain the desired contribution of materials and specified dimensions of the multicomponent extrudate profile. The screw speed of each extruder can be adjusted to the desired speed by determining the actual thickness and width dimensions of the multicomponent extrudate. The actual measurements are then fed to a computer which calculates the corresponding values of the ratios of the extruder screw speeds to line speed. using the specified dimensions desired in the extrudate, the corresponding values for the screw and line speeds are also calculated. A comparison of the speeds based on measured dimensions, with the speeds based on specified dimensions, provides a measurement by which the screw speeds may then be adjusted such that the measurements of the extrudate profile are brought closer to the specified dimensions of the multicomponent extrudate profile.
