Abstract: Disclosed is an extruder and a method for extruding cord reinforced tire components, wherein the extruder includes an extruder head with a die and a cord guide, wherein the die is provided with a cross sectional profile that defines a first cross section of the extrusion material in the die, wherein the cross sectional profile has a profile height, wherein the cord guide is arranged for guiding the cords into the die at a cord entry height, wherein the extruder head is provided with first heating elements, wherein the extruder comprises a control unit that is operationally connected to the first heating elements for generating an adjustable height temperature gradient in the extrusion material across the profile height to control swelling of the extrusion material relative to the cord entry height from the first cross section to a second cross section after the extrusion material leaves the die.

Abstract: Disclosed is an apparatus and a method for converting a sheet into a continuous strip, wherein the sheet has a sequence of cuts extending in a cutting direction transversely across the sheet with respect to the longitudinal direction to form a plurality of interconnected sheet sections, wherein the continuous strip has zig-zag sections, wherein the sheet sections are arranged to be pulled apart in a feeding direction to form the zig-zag sections, wherein the apparatus includes a separator device with a retaining device for retaining an upstream sheet section with respect to a consecutive downstream sheet section in the feeding direction and a sensor device for detecting the pulling apart of the downstream sheet section from the upstream sheet section.

Abstract: A stitching roller is provided for stitching a strip, in particular a continuous strip for strip-winding. The stitching roller includes a roller body that is rotatable about a roller axis. The roller body comprises a circumferential member and a support member provided with a connection end that is connected to the circumferential member and a base end for coupling of the stitching roller to a rotation shaft. The support member is made of a flexible material that allows for the circumferential member to tilt relative to the base end from a neutral orientation into a tilted orientation. The support member includes one or more reinforcements that reinforce the axial stiffness of the support member from the outer radius towards the inner radius.

Abstract: Provided is an extruder and a method for extruding cord reinforced tire components, wherein the extruder has an extruder head with a die and a cord guide. The die is provided with a cross sectional profile that defines a first cross section of the extrusion material in the die, wherein the cross sectional profile has a profile height. The cord guide is arranged for guiding the cords into the die at a cord entry height. The extruder head is provided with first heating elements. The extruder has a control unit that is operationally connected to the first heating elements for generating an adjustable height temperature gradient in the extrusion material across the profile height to control swelling of the extrusion material relative to the cord entry height from the first cross section to a second cross section after the extrusion material leaves the die.
