ABSTRACT:
A lagging segment having a leading edge in the form of tabs and recesses and a trailing edge in the form of tabs and recesses whereby adjacent segments can be welded to the face of a pulley without damaging elastomer by placing adjacent segments around the face of a pulley with the tabs of the leading edge positioned within the recesses of the trailing edge of adjacent segments and spaced with an air space between the tabs and recesses of adjacent segments such that welds at the ends of the tabs are separated by a heat insulating air space from the recess of the adjacent segment, whereby the spacing between the elastomer portions of adjacent segments is diminished.
