Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
152 words
A METHOD OF DEPOSITING A VARIABLE THICKNESS ELASTOMERIC LAYER ALONG AN OUTER PERIPHERY OF A TIRE CASING DURING A SINGLE OPERATING CYCLE, SAID METHOD INCLUDING THE STEPS OF LOCALLY EXTRUDING A FLAT ELASTOMERIC RIBBON HAVING A WIDTH GREATER THAN THE MAXIMUM THICKNESS OF SAID LAYER, APPLYING THE FREE END OF SAID RIBBON TO A POINT ALONG ONE EDGE OF SAID LAYER, THEREAFTER SPINNING SAID CASING AROUND ITS SPIN AXIS AND SIMULTANEOUSLY MOVING AT A VARIABLE RATE SAID CASING IN THE DIRECTION OF SAID SPIN AXIS TO MAKE SAID RIBBON FOLLOW A PATH OF A VARIABLE PITCH SPIRAL, GENERATING A VARIABLE MAGNITUDE SIGNAL DURNAL IN SYNCHRONISM WITH AND TO THE EXTENT SO AS TO MAKE SAID SIGNAL REPRESENT THE DESIRED THICKNESS OF SIAD LAYER AT ANY GIVEN INSTANT OF SAID CYCLE, AND CONTROLLING SAID RATE OF TRANSVERSE MOVEMENT WITH THE AID OF SAID SIGNAL TO MAKE SAID RIBBON FOLLOW SAID VARIABLE PITCH SIGNAL.
