The present invention may manufacture a composite pipe by forming an adhesive layer and a resin layer on an outer surface of a metal pipe, and although the composite pipe is wound in a ring shape after the composite pipe is manufactured, a circular cross sectional shape may be maintained without deformation, and after the composite pipe is straightened for the purpose of construction, separation or buckling may be prevented, resulting in excellent transportability and constructability of a product.

The invention relates to an extruder system and a method for extruding cord reinforced extrudate, in particular for tire components, wherein the extruder system comprises an extruder head with flow channels for receiving an extrusion material from an extruder, a die for receiving said extrusion material from the flow channels and a cord guide for guiding cords side-by-side in a cord plane into the die, wherein the extruder head is provided with an insertion slot that extends in an insertion direction parallel to the cord plane through the extruder head, wherein the flow channels debouch into the insertion slot at a flow area, wherein the insertion slot is arranged for receiving the die and the cord guide in the insertion direction into a die position downstream of the flow area and a cord guide position upstream of the flow area, respectively, with respect to the insertion direction.

In a method of manufacturing a rubber coated twisted wire cord, when an outer circumferential surface of a twisted wire cord that is moving from an unreeling unit to a winding unit is coated with unvulcanized rubber extruded by a rubber extruder, by a coating unit disposed between the unreeling unit and a winding unit, in a state of additional tension being imparted on the moving twisted wire cord by a tension imparting unit disposed at a nearby position on an upstream side from the coating unit in a moving direction of the twisted wire cord, the unvulcanized rubber coats the outer circumferential surface of the twisted wire cord in this state to continuously manufacture a rubber coated twisted wire cord.

A weatherstrip assembly includes a body having a carrier or core formed from a first metal for providing strength and rigidity to the body. A show surface of the weatherstrip assembly is formed of a second metal different than the first metal. The second metal acts as the show surface of the weatherstrip assembly. An isolative, electrically low conductivity layer is received only on portions of the first metal that are disposed adjacent to portions of the second metal and potentially subject to electrical contact therebetween.

This disclosure relates generally to corrugated pipe, and more particularly to corrugated pipe with an outer wrap. In one embodiment, a pipe includes an axially extended bore defined by a corrugated outer wall having axially adjacent, outwardly-extending corrugation crests, separated by corrugation valleys. The pipe also includes an outer wrap applied to the outer wall. The outer wrap may include fibers and plastic. The outer wrap may span the corrugation crests producing a smooth outer surface.

A method and device for producing metal wire by sheathing a wire with an elastomer compound coming from an extruder is described herein. The aspects disclosed herein may include a feed canal for feeding a sheathing die, through which the wire is made to pass at a pre-established nominal speed. Various temperatures are controlled during the method based on a variety of parameters such as the measured speed at which the wire is moving is other than the nominal speed.

A drive cable for actuating a vehicle element movable relative to a vehicle body is provided, the drive cable having a cable body having a cable core around which a coil following a helical line is coiled, the coil serving to engage with a gear wheel, the cable body being provided with a cable sheath. The cable sheath is glued to the coil.

An apparatus for extruding a jacket and/or insulative material onto an extruded product with one or more longitudinal stripes incorporated onto the surface of said extruded product comprising a body, a primary feed conduit for conveying a primary extrusion material, a striping die, a secondary feed conduit for conveying a secondary extrusion material, a striping die adapter, a striping feed conduit extending through the striping die adapter for conveying striping extrusion material. The striping die adapter may also include a thermocouple for maintaining the viscosity of the striping extrusion material and a thermocouple for monitoring the temperature of said striping die adapter. The striping die includes one or more striping extrusion outlets for conveying striping extrusion material onto the extruded product. The striping die may also include a wishbone-shaped trough for delivering equal amounts of striping extrusion material to said extrusion outlets for extrusion onto the product.

An inline method for producing a spring strip profile (1) for a slatted frame that comprises at least one core strand (2) formed by a fiber-reinforced plastic and at least one thermoplastic cover layer (3) surrounding the core strand (2), comprises at least the following steps: joining multiple fibers, threads and/or filaments to form a fiber bundle (2.1); impregnating the fiber bundle (2.1) with a thermally activatable reaction resin; molding the outer contour of the fiber bundle (2.1) impregnated with the reaction resin; thermally activating the reaction resin (2.1) to form a cured core strand; introducing the core strand (2) into an extruder head (110); applying thermoplastic melt in the extruder head (110) to form the cover layer (3) on the spring strip profile (1); and cooling and calibrating the spring strip profile (1) in a cooling and calibrating device (111, 112, 113). The outer contour of the fiber bundle (2.1) is wrapped around, in a winding machine (105), by at least one thread or filament (2.2) supplied laterally in relation to the fiber bundle in at least one position and orientation, and, in a heating section (106), before the core strand (2) is introduced into the extruder head (110), at least a partial curing of the reaction resin is achieved, at least in the wrapped outer layer of the fiber bundle (2.1).

A corrugated pipe includes a corrugated pipe body circumscribing a hollow conduit and including alternating ribs and valleys extending along a longitudinal axis between a first end and a second end thereof. An electrically conductive wire is embedded in the corrugated pipe body, so that the wire spans adjacent ribs and valleys and extends substantially parallel to the longitudinal axis between the first and second ends.
