摘要： A puller apparatus has a path through which an extrusion travels downstream from an outlet of an extruder and upper and lower extrusion puller members that define a portion of the path. At least one of the extrusion puller members is a drive member to provide forward motion to an extrusion. A mounting arm is moveably mounted to the puller apparatus at a mounting location. The mounting arm has a first portion on one side of the mounting location and a second portion on an opposed side of the mounting location. The upper extrusion puller member is mounted to the first portion of the mounting arm. The mounting arm is movable from a lowered position in which the upper extrusion puller member is positioned to engage an extrusion in the path and a raised position in which the upper extrusion puller member is spaced upwardly from the lowered position.

摘要： A method of forming a composite panel in-line is disclosed. The method includes the steps of forming a hot thermal plastic sheet of material and providing the hot thermal plastic sheet of material to a punch having punch members extending outwardly therefrom. The hot thermal plastic sheet of material is advanced through the punch in order to form apertures through the hot thermal plastic sheet of material such that each aperture extends from an outer surface of the hot thermal plastic sheet of material to an inner surface of the hot thermal plastic sheet of material. An outer metal sheet and an inner metal sheet, respectively, are coupled to opposing sides of the hot thermal plastic sheet of material.

摘要： The machine includes an extrusion head having flow ducts, the inlet orifices of which are connected to the outlets of at least two extruders for supplying extruded strips made of elastomeric compounds. The outlet orifices lead into a die which is adjacent to a roller and is designed to cooperate with the latter to shape the profiled element strip. The roller has a central axis surrounded by an external surface intended to receive the profiled element strip and a means for driving the roller in rotation about its central axis. The flow ducts are mutually parallel and are perpendicular to the circumferential direction of the roller, and the profiled element strip is joined to the receiving surface of the roller along an equivalent length of at least 700 mm.

摘要： A method and apparatus for extrusion of an article is provided. A die assembly can apply flows of thermoplastic material to an array of reinforcing cables to form a composite extrusion. A slider fabric can be bonded to one side of the composite extrusion. After exiting the die assembly, the slider fabric can act to support the extrudate as it passes along an elongate mandrel, which can cause the base of the slider fabric to change shape from a flat profile to the final internal profile of the article. The extruded article can then be cooled to solidify the material. The die can include cooling for the slider fabric and means for promoting penetration of the thermoplastic into reinforcing cables.

摘要： A method and an apparatus for forming annular doses provides a flow of plasticised material supplied by an extruder which passes through a channel that is first cylindrical and then annular. The material exits from an annular outlet in front of which a cutting element passes that separates an annular dose of material. The dose is deposited on a surface of a capsule having a capacity to adhere to the dose that is greater than the cutting element. The surface and the cutting element are distanced from one another in such a manner that the annular dose remaining adhering to the capsule is detached from the element. Detachment can be promoted by a flow of air.

摘要： A method of and apparatus for extruding an article of uniform cross-section, the article including a thermoplastic material and at least one cable for inhibiting stretch of the article. The cable is supplied to a respective tube and is conveyed between upstream and downstream ends. The thermoplastic material may be supplied to the downstream end of the tube. The thermoplastic material is brought together with the cable to embed the cable within the thermoplastic material, thereby forming a composite extrudate. The tube is configured to at least hinder movement of loose windings of the cable from the downstream end towards the upstream end, which may prevent or at least reduce incidence of “birdcaging”.

摘要： Method for regulating an extrusion device for the manufacture of a continuous strip of profiled product (P) made of an elastomeric compound, comprising a screw rotationally driven in a fixed barrel the outlet of which comprises an extrusion die and at least one rotationally driven cylindrical roller, the rotational speed of the screw (Ωscrew) being directly connected to the rotational speed of the roller (Ωroller) by a proportionality coefficient, including: for a given elastomeric compound and a given profiled product (P), determining a setpoint value Ks of the proportionality coefficient, measuring the thickness (e) of the profiled product (P) leaving the extrusion die at each instant and correcting the value of the proportionality coefficient to Ks′, correcting the rotational speed of the screw taking account of the corrected value Ks′ of the proportionality coefficient, such that Ω′screw=Ks′*Ωroller The roller speed is adjusted as a function of the corrected value Ks′ of the proportionality coefficient.
