Method and apparatus for the simulation of the build up of the tread on a tire carcass
First Claim
1. A method for simulating the manner in which a ribbon of known profile is wrapped around a carcass of known profile in accordance with a predetermined winding specification, said method comprising the steps of:
- storing the profile of said ribbon, the profile of said carcass, and said winding specification in a memory;
calculating, for at least one cross-section of said carcass, the profile of a final ribbon build which will be created at said cross-section when said ribbon is wrapped around said carcass in accordance with said winding specification, said calculating step being performed as a function of said profile of said carcass, said ribbon profile and said winding specification; and
displaying, for each of said cross-sections, said profile of said final ribbon build.

Abstract
A method and apparatus for simulating the manner in which a ribbon of known profile is wrapped around a carcass of known profile in accordance with a predetermined winding specification is disclosed. The profile of the ribbon, the profile of the carcass and the winding specification are stored in a memory together with the desired final profile of the ribbon build. The profile of the final ribbon build, which will be created at a selected cross-section of the carcass when the ribbon is wrapped around the carcass in accordance with the winding specification, is calculated. The final ribbon build so calculated is displayed on a video display which also displays the desired final profile so that the profile created by the predetermined winding specification can be compared to the actual profile which will be produced by the winding specification.

19. Apparatus for simulating the manner in which a ribbon of known profile is wrapped around a carcass of known profile in accordance with a predetermined winding specification, said apparatus comprising:
-
memory means for storing the profile of said ribbon, the profile of said carcass and said winding specification; means for computing, for at least one cross-section of said carcass, a profile of the final ribbon build which will be created at said cross-section when said ribbon is wrapped around said carcass in accordance with said winding specification, said computing means computing said profile of said final ribbon build as a function of said profile of said carcass, said ribbon profile and said winding specification; and means for displaying, for each of said cross-sections, said profile of said final ribbon build. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)

37. A method for determining a top profile of a deformed cross-section of a flexible ribbon having a known non-deformed profile when said flexible ribbon has been placed on a surface having a known profile so as to assume said deformed cross-section, said method comprising the steps of:
-
computing said top profile taking into account said non-deformed profile of said ribbon, a location of said ribbon with respect to said surface of known profile, and said known profile of said surface; and displaying said top profile relative to said surface. - View Dependent Claims (38, 39, 40)
