摘要： A parison extruding head provided with an inlet at one side thereof, transverse to the axis thereof, and including a diverter to change the direction of movement of plasticated resin to flow axially of the extruder head from the entering direction. The diverter effects smooth transition in the path of movement of such plasticated resin without impeding or entrapping any of the same, thereby avoiding burning of the resin or other deleterious effects therein.

摘要： A wire is fed from a supply roll to a device which twists the wire on its longitudinal axis and continuously forms the twisted wire into a non-rotating helical coil. The coil is fed directly from the device through a plastic tube extruding head by a rotatable screw which extends within the coil, and a vacuum is created within the tube as it is extruded over the coil to shrink the tube between the turns of the coil. The coil reinforced tube may then be fed through a device which covers the tube with a continuous fabric member, and the covered tube is then fed through another extruder head which extrudes a second tube over the fabric member and shrinks the second tube onto the fabric member and the first tube. The coil feeding screw, the fabric member forming device, the extruders, and the tube feeding devices are driven at speeds correlated with the speeds of twisting and feeding the wire to provide a continuous conduit forming operation.

摘要： An extruding apparatus wherein a die-head containing dies for forming two or more layers of thermoplastic material, such as on a core passing through the head, is supplied with material by as many extruder barrels as there are layers. The barrels are connected to the die-head at different points, one of the barrels being fixed to the die-head and the other barrel or barrels being connected to the die-head by a connector which compensates for thermal expansion of the barrels and die-head. This connector has a telescoping component and a universal joint component to compensate for thermal expansion in any direction.

摘要： A blowhead for making tubular plastics film comprising a housing having a central aperture for installing special equipment, a lateral supply passage in the housing for the entry of molten plastics material, branch passages which branch from the supply passage and extend, each in its own direction, through 90* about an insert in the housing, are then shortly curved to divert the flow of plastics material axially of the blowhead against the direction in which film is blown, and then diverge constantly in the peripheral direction until they merge at positions at an end of the insert, recesses formed in the housing adjacent the end of the insert to direct the flow of plastics material over projecting surfaces provided on the end of the insert and into an annular passage leading to a nozzle orifice from which the plastics material is blown as a film, the projecting surfaces and recesses extending in the direction opposite to the film blowing direction such that, starting from the sharp curvatures, the flow path for the plastics material to the nozzle orifice has the same length in every angular direction of the diverging portions of the branch passages.

摘要： AN EXTRUDER CROSS HEAD FOR EXTRUDING PLASTIC MATERIAL ONTO A CORE WHICH TRAVELS LONGITUDINALLY THROUGH AN ANNULAR DIE PASSAGE DEFINED BY INNER AND OUTER DIES CHARACTERIZED IN THE PROVISION OF A LEVER ACTUATED MANDREL WHICH IS WEDGED INTO AND RELEASED FROM A TAPERED BORE IN THE CROSSHEAD BODY, AD A LEVER-ACTUATED CORE GUIDE AND INNER DIE SLEEVE WHICH IS LONGITUDINALLY SLIDABLE IN THE MANDREL FOR ADJUSTMENT OF THE INNER DIE WITH RESPECT TO THE OUTER DIE. THE INNER DIE HAS INTERNAL PORTIONS FOR WRENCH ENGAGEMENT TO AVOID MARRING OR DISTORTION OF THE DIE AND CORE GUIDE SURFACES THEREOF DURING ASSEMBLY AND DISASSEMBLY OF THE SLEEVE AND INNER DIE. THE EXTRUDER CROSSHEAD HEREIN ALSO HAS CONTROLLABLE BLEED MEANS OPPOSITE THE LATERAL MATERIAL INLET AND HAS A FLOW EQUALIZER RING AROUND THE TIP OF THE MANDREL WHICH INCLUDES CONCENTRIC AND ECCENTRIC BORE PORTIONS TO EQUALIZE THE FLOW OF MATERIAL THROUGH THE ANNULAR DIE PASSAGE.
