Abstract
Abstract The present invention relates to a warp carcass for tires for bicycles in general and, in particular, for sports and race bicycles, characterized in that it comprises at least two cross-plies, formed from layers having exclusively warp threads. The plies consist of a plurality of threads, arranged with an adjoining relationship and mutually pressed so as to assume a substantially elliptical cross-section shape. On one face of the plies there being moreover provided a binding layer consisting of a rubber latex.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
62 words
A warp carcass for tires for bicycles in general, in particular for sports and race bicycles, characterized in that it comprises at least two crosses plies, formed from layers including exclusively warp threads, said plies consisting of a plurality of adjoining and mutually compressed threads, having a substantially elliptical configuration, a binding layer being moreover provided on one face of said plies.
Claim 2
Dependent Claim
62 words
A warp carcass for tires for bicycles in general, in particular for sports and race bicycles, characterized in that it comprises at least two crosses plies, formed from layers including exclusively warp threads, said plies consisting of a plurality of adjoining and mutually compressed threads, having a substantially elliptical configuration, a binding layer being moreover provided on one face of said plies.
Claim 3
Dependent Claim
33 words
A warp carcass for tires for bicycles in general according to Claim 1, characterized in that the threads used for making said plies have a synthetic thread core encompassed by a natural thread.
Claim 4
Dependent Claim
24 words
A warp carcass according to Claim 1, characterized in that said binding layer consists of a latex, adapted to partially soak the adjoining threads.
Claim 5
Dependent Claim
33 words
A warp carcass according to one or more of the preceding Claims, characterized in that it comprises very small serpentine particles of molecular aggregates of said latex binding the fibers of adjoining threads.
Claim 6
Dependent Claim
27 words
A warp carcass according to one or more of the preceding Claims, characterized in that the face of said ply facing the cylinder is not impregn ated.
Claim 7
Dependent Claim
32 words
A warp carcass according to one or more of the preceding Claims, characterized in that said at least two crossed plies are made by spiral cutting threads helicoidally wound on a cylinder.
Claim 8
Independent Claim
50 words
A method for making a warp carcass tire, characterized in that it comprises the steps of spiral winding on a heated cylinder one or more threads fed from one or more thread packages and subjecting the thread being wound to a pressing force in the axial direction of said threads.
Claim 9
Independent Claim
50 words
A method for making a warp carcass tire, characterized in that it comprises the steps of spiral winding on a heated cylinder one or more threads fed from one or more thread packages and subjecting the thread being wound to a pressing force in the axial direction of said threads.
Claim 10
Independent Claim
37 words
A method according to the preceding Claim, characterized in that the pressing force is a mechanical pressing force, said force being provided by a pressing pushing member adapted to operate on the outer surface of said cylinder.
Claim 11
Independent Claim
74 words
A method according to one or more of the preceding Claims, characterized in that it comprises the step of rubberizing the threads wound on said cylinder by means of a synthetic or natural latex, adapted to soak in a controlled way said threads and bind the fibres of said threads by means of microscopic serpentine particles of molecular aggregates of said latex which is helt and filtered by the draining effect of said threads.
Claim 12
Independent Claim
53 words
A method according to one or more of the preceding Claims, characterized in that the soaking depth of said latex is greater than the soaking depth of said molecular aggregates, so as to cause the threads to contract toward the surface facing the heating cylinder, but so as not to reach said surface.
Claim 13
Independent Claim
54 words
A method according to one or more of the preceding Claims, characterized in that it comprises the step of heating said latex by said cylinder so as to dry said latex and stabilize the textile tube wound and compacted on said cylinder, before spiral curring said tube to provide lozenge patterns to be doubled.
