The inner flow path may be configured to direct a flow of an inner layer around a conductor. The outer flow path may be configured to direct a flow of an outer layer around the inner layer. The at least one sealant flow path may extend to a connecting point with the inner flow path and the outer flow path. The at least one sealant flow path may be configured to direct a sealant to fill at least one sealant channel region between the inner layer and the outer layer. The connection point may be configured to cause the flow of the inner layer and the flow of the outer layer to join before the sealant fills the at least one sealant channel region.

  • Patent number: 8197242
    Abstract: A device for continuously sheathing a ply of threads, said ply being formed by an array of approximately mutually parallel threads. The device includes a thread guide, a coating chamber into which a first feed channel and a second feed channel run, which are independent of each other, connected to a first feed device and to a second feed device respectively and capable of delivering a first material and a second material under pressure and with a defined flow rate, and the outlets of which channels are placed above and below the plane of the ply of threads, and an output die. Pressure-measuring device, connected to a controller for controlling the pressure of each of the feed devices, are placed in the coating chamber facing and in line with each other, on either side of the plane of the ply and in the immediate vicinity of the outlet for the feed channels.

  • Publication number: 20120052245
    Abstract: A method and apparatus for making a segmented multicomponent polymeric film. The method includes providing at least two separated melt streams, including at least two different polymeric compositions, that are separated in a first separation dimension; dividing in a second separation dimension substantially orthogonal to the first separation dimension at least some of the separated melt streams into at least two segmented flow streams; redirecting at least some of the segmented flow streams, with at least some of the segmented flow streams being sequentially redirected in both separation dimensions; and converging the segmented flow streams into a segmented multicomponent polymeric film. A segmented multicomponent polymeric film having projections is also presented, the film having a top surface and a bottom surface, each surface having a different arrangement of polymeric segments that at least partially alternate along the film's cross direction and extend continuously in the film's length direction.

  • Patent number: 7987885
    Abstract: A system and method are disclosed for producing a continuous filament reinforced thermoplastic profile having consistent cross section. A continuous reinforcing filament is pre-wetted with a first thermoplastic resin and introduced into a die, where it is contacted with a second thermoplastic resin extruded from an extruder at melt state. The temperature of the die is carefully controlled so that the pre-wetted filament and first resin do not cure or solidify until after they have contacted and mixed with the second thermoplastic resin. The mixture temperature is then controlled to make a substantially solidified profile pre-shape. A capping layer comprising a third thermoplastic resin is then coextruded onto the outer surface of the pre-shape. A multistage die for bringing together the filament and thermoplastic resins and for maintaining appropriate temperatures at each stage of the profile-forming process is also disclosed.

  • Patent number: 7887313
    Abstract: To provide a mold apparatus for resin encapsulation, which is small in number of components, has a simple driving mechanism, is easy in assembly or disassembly work, requires no labor for maintenance and has good workability; and a resin encapsulation method. Therefore, of a lower cavity bar 51 and an upper cavity bar 26, a plurality of groove-shaped pots 52 are provided in parallel at a predetermined pitch in a region where a substrate board is disposed, and each groove-shaped pot 52 is individually provided with a plurality of cavities 54 in parallel through runners. Then, a plunger plate 60 inserted in the grooved-shaped pot 52 in a manner so as to be able to move up and down is driven by a plunger 76, whereby a resin for encapsulation inserted into the pot 52 is melted with the plunger plate 60, and the melted resin is filled in the cavities 54 through the runners.

  • Patent number: 7871256
    Abstract: A cable guide system and method are disclosed for a mold forming and extruding machine. The machine has a pair of spaced apart vertical members. The cable guide system includes a support shaft secured to the pair of vertical members. The support shaft retains a first stop member, a tensioning device, a spool loaded with a flexible reinforcement cable, and a second stop member. The spool cooperates with the tensioning device to prevent the cable from prematurely unraveling. The cable guide system further includes a guide member located below and forward of the spool and in horizontal alignment with a plunger. The guide member is capable of changing the direction of the flexible reinforcement cable as it is unwound from the spool. The plunger is capable of extruding a moldable substance from the machine while allowing the flexible reinforcement cable to pass through an aperture formed therein.

  • Publication number: 20100316754
    Abstract: Die tooling is formed by forming a series of passages extending in the length of the tooling where each passage has a circumference defined within a body member of the tooling. Preferably the passages are primarily formed using a drilling procedure. The passages define a predetermined pattern of outlets adjacent the extrusion outlet or outlets. The passages between the inlets and outlets can be formed in a series of connected body members with each passage extending through each body member. Die tooling of this design is more robust and cost effective to manufacture.
