摘要： Coextrusion apparatus for varying the inner profile of a generally tubular extrudate formed by a first stream of elastomeric material by an axially movable inner die ring which varies the size of an orifice and consequently the flow of a second stream of elastomeric material which is deposited on the inner surface of the tubular extrudate. A compensating ring is axially slidably mounted within the inner die ring and moves generally in an opposite direction to the movement of the die ring to compensate for pressure changes within the second stream of material caused by varying the size of the orifice, to provide an accurately controlled initiation and termination of the material. Pistons are formed integrally on the inner die ring and compensating ring and are located within annular fluid pressure chambers whereby the flow of fluid into the chambers will coordinate the movement of the die ring and compensating ring. A reinforcing guide directs the plurality of fiber reinforcing elements into the tubular extrudate prior to depositing the variable stream of elastomeric material on the inner surface of the extrudate. In another embodiment, a generally constant outer layer of a different elastomeric material may be applied to the outer surface of the tubular extrudate simultaneously with the varying of the inner profile thereof.

摘要： A system for handling a flexible thin wall tubular extrudate of an elastomeric material of the type used as a body ply element for the manufacture of tires, and for cutting-off a predetermined length sleeve of the extrudate and delivering the sleeve to a discharge station. A pair of grippers is movably mounted on carriage assemblies which move the grippers horizontally and transversely with respect to the axis of the extrudate. The leading gripper provides tension to the extrudate and pulls it along a production axis. The trailing gripper engages the extrudate and moves in unison with the extrudate and the leading gripper along the production axis. The grippers completely circumferentially envelop the length of sleeve to be cut from the extrudate and retain the shape of the extrudate by applying a vacuum thereto. A cutting mechanism having a fixed motor driven blade and a pair of similar pivotally mounted blades moves vertically down into contact with the extrudate between the pair of grippers. The rotating blades are rotated through at least 120.degree. arc to achieve a 360.degree. cut on the extrudate as it is being moved under tension longitudinally by the grippers. After completion of the actual cutting operation the leading gripper transfer the severed sleeve to a discharge station and returns to a home position and now becomes the trailing gripper. The previous trailing gripper becomes the leading gripper and continues to advance the extrudate along the production axis and apply tension thereto for the next cutting operation.

摘要： Coextrusion apparatus for varying the outer profile of a generally tubular extrudate formed by inner and outer streams of elastomeric material by varying the annular end opening of an elastic die ring which varies the size of an outer extrusion orifice and consequently the flow of the outer stream of elastomeric material which is deposited on the outer surface of the tubular extrudate. A hydraulically moveable piston is axially slideably mounted for engagement with the elastic die ring and has a wedge-shaped camming surface which moves along the outer surface of the elastic die ring to vary the size of the outer extrusion orifice and consequently the amount of elastomeric material extrudated therethrough. A linear motion detector is connected to the piston to detect the amount of linear axial movement of the piston to provide control signals for controlling the movement of the piston. The orifice for the inner stream of elastomeric material is located slightly upstream of the orifice for the outer stream of elastomeric material and is generally fixed. A reinforcing guide directs a plurality of fiber-type reinforcing elements into the tubular extrudte generally at the merger of the inner and outer streams of elastomeric material. A method for varying the outer profile of the tubular extrudate is also presented.

A method for coextruding an annular seamless component of reinforced elastomeric material is also presented.

摘要： Coextrusion apparatus for forming tubular elastomeric ply made up of first, second and third concentric streams of elastomeric material and a pair of coaxial helical patterns of individual reinforcing elements wound in opposite direction with respect to each other contained within the first and third streams of elastomeric material and separated by the second stream of elastomeric material. A pair of reinforcing element guides are rotatably mounted within the apparatus between stationary flow channels for the three streams of elastomeric material, and are rotated in opposite directions with respect to each other. The two helical patterns of reinforcing elements and three streams of elastomeric material merge together substantially simultaneously in concentric circles which lie in a plane generally perpendicular to a central axis of the coextrusion apparatus to form the tubular ply. A method for producing such a reinforced tubular elastomeric ply also is presented.

摘要： A reaction cell system for measurement of catalyst demand includes a spherical chamber having an inlet with a diametrically opposed outlet. An optical cylinder traverses the spherical chamber above an agitator maintained at the bottom thereof. The optical cylinder has a slit passing therethrough adjacent a wall of the spherical cylinder such that laminar and uniform flow of fluid within the chamber passes through the slit. The valving between the inlet and outlet of the chamber is such that the inlet valve opens before and closes after similar actuation of the outlet valve. A source of catalyst and indicator communicate with diaphragm dispensers which are operative to inject precise volumes of catalyst and indicator into the spherical chamber. A valve network allows for passage of the catalyst and indicator into the chamber or into measurement standards. Additionally, the valve network communicates with the source of fluid that feeds the chamber to allow for complete and total flushing of the system.

摘要： Coextrusion apparatus for varying the outer profile of a generally tubular extrudate formed by merging inner and outer streams of elastomeric material by varying the size of the annular outer extrusion die opening by an axially moveable die ring which varies the flow of the outer stream of elastomeric material which is deposited on the outer surface of the tubular extrudate. The die ring is formed on the end of a hydraulically moveable piston and is axially slideably moved along and is located concentrically about the tubular extrudate. A first annular tapered surface of the die ring moves along a similar tapered surface of a fixed conical-shaped die pin to vary the size of the outer extrusion orifice formed therebetween. A second surface, oppositely tapered to that of the first tapered surface of the die ring and formed integrally therewith as a one-piece member, communicates with the flow channel of the outer elastomeric material stream and continuously compensates for a change in pressure within the outer flow stream caused by varying the flow volume of the outer stream at a location generally adjacent the application of the outer stream on the outer surface of the tubular extrudate. A reinforcing guide directs a plurality of fiber-type reinforcing elements into the tubular extrudate generally at the merger of the inner and outer streams of elastomeric material. A method for varying the outer profile of the tubular extrudate is also presented.
