Embodiment Construction

[0169] figure 1 A schematic diagram of the process arrangement in the extruder system 22 is shown. The figure shows the flow ducts 30 and the associated extruder heads which bring the individual rubber parts to the preforming device 1 from which they are conveyed further in the extrusion direction 15 to the final molding device 20. The final molding device 20 here molds a complete rubber element 40 as the final product of the extrusion process.

[0170] figure 2 A schematic diagram showing the insertion of the outlet module 3 and the inlet module 2 of the preforming device 1 according to the invention into the receiving device 18 of the extruder system is shown. The figure shows that the side 4 of the inlet module tapers towards the contact surface 19 of the inlet module 2 , so that the inlet module 2 can be received in the receiving device 18 with a precise fit in the extrusion direction 15 . Instead, the outlet module 3 of the preforming device 1 according to the inven...

Abstract

The invention relates to a preform device for positioning extruded rubber mixtures. The invention is characterized in that the preform device consists of an inlet module (2) and an outlet module (3),wherein the inlet module (2) and the outlet module (3) each have a respective base surface (11, 12) and a respective contact surface (19, 21) opposite the base surface (11, 12, 13), and the surface area of the contact surface (19, 21) of the inlet module (2) is smaller than the surface area of the base surface (11, 12) of the inlet module (2). The invention also relates to an extruder mold systemfor molding extruded rubber mixtures into a complete rubber element (40), having the preform device and at least one final shaping device, and to a corresponding extruder system (22).

Description

technical field [0001] The invention relates to a preforming device for positioning an extruded rubber compound and to a device for molding an extruded rubber compound into a complete rubber element, comprising a preforming device and at least one final forming device Extruder molding system. The invention also relates to an extruder system. Background technique [0002] In the rubber industry, a rubber compound is extruded in an extruder and then formed into a complete rubber element with a predetermined profile in an extruder molding system. Typically, an extruder molding system includes a preforming device and a final forming device. [0003] Extruder molding systems are known in the art. For example, US 4683095A discloses an extruder device having a pre-die and a final die. [0004] The preforming units known from the prior art usually have to be used in conjunction with a final forming unit, wherein the task of the preforming unit is to guide the individually extrud...
