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.

A method for forming a composite tread, the method comprising the steps of: forming a coextruded strip of a first compound and a second compound, wherein the first compound is a tread compound, and the second compound is formed from a second compound, wherein the tread is formed from winding the coextruded strip onto the tire building drum while varying the ratio of the first compound to the second compound

A sizer for cooling an extrudate, which includes a core and a housing. The core includes an extrusion channel which accommodates the extrudate, a core cooling channel, and a core vacuum channel in fluid communication with the extrusion channel. The housing includes a housing cooling channel and a housing vacuum channel. The core cooling channel is in fluid communication with the housing cooling channel, and the core vacuum channel is in fluid communication with the housing vacuum channel.

A group of hollow modules through which the material to be extruded flows, is provided that includes at least: a rectangular heating-shaping module, in which the material undergoes a temperature increase and takes on the desired shape; and a tubular cooling-solidification module, in which the material changes from liquid to solid. A heating-reaction module is provided upstream of the heating-shaping module. The heating-reaction module includes an interchangeable hollow tube with an external heating system. The heating-shaping module includes detachable parts and includes another external heating system based on the auto-acceleration of the curing reaction and of the heat supply from said external heating system. The tubular portion between the heating-reaction module and the heating-shaping module includes a shaping coupling equipped with a through-hole. The extrusion module includes a circuit through which the polymer flows into at least two push compartments.

Disclosed herein are customizable kits of parts for the fabrication of polymer fibers. In some embodiments, the kits provided herein comprise a scaffold comprising first and second opposite surfaces and one or more pores extending through the first and second surfaces, wherein each pore comprises a first channel and a first conjunction interface. The kits additionally comprise a plurality of nozzles, wherein each nozzle comprises a second channel and a second conjunction interface, and wherein the second interface can be removably and stably coupled to the first conjunction interface of each pore while allowing a fluid through the first channel and the second channel.
