Abstract
A programming apparatus for use with a machine applying successive wraps of rubber on a tire surface during a retreading operation. The contour of the layers to be deposited is translated upon a template device by positioning of select metallic contacts. In turn, the number of wraps for a given arcuate distance are more finely defined upon a second template device. The second template being indexed with a series of metallic contacts. The entire operation is controlled electrically such that successive movement of the tire surface is correlated to arcuate distance.
Claims8
A programming assembly for use with a tire retread apparatus adapted to control the wraps of advancing rubber ribbon material as it is applied upon a tire surface supported on tire support means provided with spindle means for receiving a tire thereon, drive means for driving said spindle means through a linkage means connected between said drive means and said spindle means, said linkage means being directed by said program assembly for operation during each of two separate modes of operation, each of said modes of operation employing individual templates, wherein:
- said linkage means being moveable in a program mode in response to program information set forth on a transportable, programable template by means of a series of targets positioned in respective arcuate paths formed on said first template, the distance between each of said targets corresponding to a portion of said tire surface to be wrapped with rubber ribbon, to thusly define a ribbon wrap formation across the entire tire tread surface;
- a first sensing means mounted on movable support means within said tire retread apparatus, being adapted to travel in an arcuate path in concert with said linkage means, and being actuable by each of said targets for causing corresponding arcuate movement of said tire surface;
- a second sensing means mounted in proximity to said first sensing means on said support means being engageable therewith through actuation of switch means after the last of said targets in said programable template has been sensed;
- said first and second sensing means being jointly movable in response to a plurality of contacts disposed in a predefined arcuate path about a transportable production template disposed in said programming assembly to thereby enable said programming assembly to function in said second mode once information from said first template has been transferred to said second template to thusly control the arcuate movement of said tire surface in an incrementable fashion through said linkage means in response to said transferred information from said production template, and means for de-energizing said spindle after all of said contacts on said second template have been sensed.
