US 6,280,548 B1 · Method and apparatus for building a laminate and forming a carcass subassembly for a tire

Abstract

A method and apparatus 200 for building a laminate 10A and in forming a subassembly 10 for a pneumatic tire from an assembly of reinforced or unreinforced tire components wherein the method has the steps of providing an apparatus 200 for simultaneously forming, positioning, attaching and conveying a plurality of continuous strips of elastomeric tire components and activating the apparatus simultaneously forming, positioning and attaching the plurality of continuous strips of elastomeric tire components to adjacent strips of tire components as they are conveyed thus forming a laminate 10A of reinforced or unreinforced tire components suitable for use as a subassembly for a pneumatic tire.

A method for building a laminate from an assembly of unvulcanized tire components suitable for use in forming a first stage subassembly for a pneumatic tire, the laminate having a carcass ply in addition to other tire components, the method comprising the steps of:

providing an apparatus having a plurality of calender assemblies at spaced locations, the apparatus being capable of simultaneously forming, positioning, attaching and conveying a plurality of continuous strips of elastomeric tire components, each formed component laving a predetermined cross-sectional profile formed by a component forming depression on a calender roller of one of the calender assemblies;
and
activating the apparatus to simultaneously form, position, attach and convey the plurality of continuous strips of elastomeric tire components, each formed strip of tire components being attached directly from the component forming depression of the calender roller to a conveyor, the carcass ply or other formed component as they are conveyed thus forming the laminate of tire components suitable for use in forming first stage tire subassembly.

A method of building a laminate from an assembly of tire components suitable for use in forming a carcass for a radial ply pneumatic tire, the method comprising the steps of:

affixing a radial ply material to a conveying means, the ply material having a pair of lateral edges defining the ply width, the ply material being made of elastomeric material reinforced by cords, the cords being embedded in the elastomeric material and being parallel, substantially equally spaced, and oriented at an angle between 65° and 90° relative to the lateral edges of the ply;
conveying the ply material;
simultaneously forming a plurality of continuous strips of elastomeric tire components by an apparatus having a plurality of calender assemblies at spaced locations, each formed component having a predetermined cross-section profile formed by a component forming depression on a calender roller of one of the calender assemblies;
and
simultaneously applying the plurality of formed continuous strips of tire components while still hot to at least one side of the radical ply or another previously attached strip at the locations where each of the strips is formed directly from the component forming depression or depressions of the calender roller while the radical ply material is being linearly conveyed and as the continuous strips are simultaneously being formed, thereby, to form a laminate for use in forming a carcass for a radial ply pneumatic tire.
