A method of forming a hose includes: extruding a web of plastics material from a first extruder; helically winding the extruded web about a mandrel or at least one rotating rod to form a wall of the hose; feeding an electrical wire into a second extruder; extruding a bead of plastics material around the electrical wire from the second extruder such that the extruded bead includes the electrical wire at a location within a cross-section of the extruded bead; cooling the extruded bead to cool the plastics material adjacent the location to prevent migration of the electrical wire away from the location; re-heating the extruded bead to cause outer surface portions of the plastics material of the extruded bead to become molten; and helically winding the extruded bead onto and about an external surface of the wall to provide the wall a support helix that incorporates the electrical wire.

A method and system are disclosed. A method of printing onto a base having an upper surface spaced from a lower surface by a base thickness includes dispensing a yarn from a nozzle of a printing system and selectively attaching the yarn to a first attachment region. The step of dispensing the yarn includes dispensing a heat-moldable material and a melt-resistant material. The step of selectively attaching the yarn to the first attachment region includes moving the nozzle into the first attachment region. The step of moving the nozzle into the first attachment region reduces the base thickness by a prodding distance. The heat-moldable material bonds to the first attachment region.

An extruder system and a method for extruding cord reinforced extrudate, in particular for tire components, are provided. The extruder system includes an extruder head with flow channels for receiving an extrusion material from an extruder, a die for receiving the extrusion material from the flow channels, and a cord guide for guiding cords side-by-side in a cord plane into the die. The extruder head is provided with an insertion slot that extends in an insertion direction parallel to the cord plane through the extruder head. The flow channels debouch into the insertion slot at a flow area. 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.

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.

An extrusion- or pultrusion device (1) for forming a profile product (2) in a production direction (Y), said device comprising: a rotating die (3) having two opposite first and second side walls (5, 6) and an outer circumferential surface (4) there between, wherein the rotating die (3) comprises a first side portion (23) in connection to the first side wall and a second side portion (25) in connection to the second side wall (6) and a mid-portion (22) extending between the first and second side portions (23, 25), wherein the width of the first channel section (9) is, at least along a portion of its length and at least along a portion of its height, less than a distance between the two opposite side walls (5, 6) of the rotating die (3).

The present invention provides an insulated pipe comprising one or more inner pipes comprising a plastic, a flexible vacuum insulation panel in the form of units joined to each other wrapped around at least one of the one or more inner pipes, one or more insulation layers, and an outer jacket. The present invention further provides a method and an apparatus for producing the insulated pipe.

Calendering installation for the production of a reinforcing ply (600) for a tire, which has a frame (100), two extruders (200, 300) for feeding elastomer material, a reinforcing-thread feeding device (400), a calender (500) having a first pair of counter-rotating rollers, with a first working roller (52) and a first shaping roller (51), and a second pair of counter-rotating rollers, with a second working roller (53) and a second shaping roller (54), wherein a calendaring nip (59) is formed between the working rolls (32, 53) in order to receive a first calendered rubber ply (57) delivered by the first pair of rollers (51, 52), a second calendered rubber ply (58) delivered by the second pair of rollers (53, 54), and the reinforcing threads (45) in order to supply the calendered reinforcing ply (600), which is conveyed to the outlet of the installation via GUIDE ROLLERS (62, 63). According to the invention, the two extruders (200, 300) are superposed and arranged on either side of a horizontal plane P extending at the level of the guide rollers (62, 63).

A method and a device for manufacturing a rubber coated cord, comprising:

a rubber coated cord including a preceding cord is manufactured by causing the preceding cord to pass through a preceding head while filling the preceding head with unvulcanized rubber extruded from a rubber extruder, and a rubber coated cord including a next cord is manufactured by setting a leading edge portion of the next cord in a state where the leading edge portion of the next cord has passed through the next head in advance, manufacturing a predetermined length of the rubber coated cord including the preceding cord, and subsequently causing the next cord including a leading edge portion side range bonded to a trailing edge portion of the rubber coated cord including the preceding cord to pass through the next head while switching from the preceding head to the next head.

The method for manufacturing an individually sheathed strand comprises: conveying a group of metal wires through a die; upstream of the die, applying a first filler product to at least a first portion of the strand; upstream of the die, applying a second filler product to at least a second portion of the strand distinct from the first portion; and extruding a plastic around the group of metal wires passing through the die, so as to envelop the group of metal wires covered with the first and second filler products in a continuous sheath formed of the extruded plastic. The second filler product has greater adhesion to the group of metal wires than the first filler product.
