Claims

[Claims for Utility Model Registration] (1) A plurality of wraps of formed strips of treaded material are placed on the surface of a rotatable tire casing at precise predetermined positions defined by X and Y coordinates. and presses the strip onto the surface of the tire casing at a predetermined angle defined by the Z coordinate with respect to the surface of the tire casing, the device being mounted to rotate around a spindle axis. a tire casing support wheel mounted on the upper platform; and a winding head mounted on a winding head strut, the winding head strut having a base rotatably mounted on the upper platform; The platform is slidably mounted on a lower platform for movement in a direction parallel to the spindle axis, and the lower platform is supported to move toward and away from the spindle axis. strut drive means for rotating said winding head strut and for pressing said strip against said surface of said tire casing at said predetermined angle; , rotation control means for actuating the strut drive means to rotate the strut through a predetermined angle with respect to the plane of the tire casing; drive means; said upper platform drive means for moving said upper platform into position axially of said tire casing when said strip of tread material is wrapped around a surface of said tire casing; upper platform control means for actuating the lower platform on the support surface; lower platform drive means for moving the lower platform on the support surface; and lower platform drive means for moving the lower platform on the support surface; lower platform control means for actuating the lower platform drive means to move the lower platform into a predetermined position radially of the tire casing; and a spindle for rotating the tire casing support wheel. Depending on the drive means and feed rate input,
spindle rotation control means operative to cause the spindle drive means to rotate the tire casing support wheel at varying speeds; and upstream of the winding head for sensing the rate of feed of the strip to the winding head. tread material wrapping around a tire casing having a speed sensor engaged with the strip of tread material; and a spindle rotational speed sensor attached to the spindle for sensing the rotational speed of the spindle. Device. (2) The direction of the winding head column from the base toward the winding head is generally inclined away from the axis of the spindle.
The described tread material wrapping device. (3) The tread material wrapping device according to claim 1, wherein the spindle rotation control means has a Y coordinate input for changing the rotational speed of the tire casing support wheel when the Y coordinate changes. (4) mounted on the winding head to engage the surface of the tire casing at the winding head for detecting the actual surface velocity as the strip is wound onto the surface of the tire casing; 2. The tread material wrapping apparatus of claim 1, including a wrapping surface speed sensor coupled to said spindle rotation control means for finely adjusting the rotational speed of said tire casing support wheel.
