ABSTRACT:
A mat testing apparatus having an enclosed test chamber with a pair of moveable electrode plates that are cooperative with two pairs of vertically disposed stationary electrode plates. Such pairs of plates are cooperative to define a clearance space between each pair which are operative to receive a portion of a mat material for testing its non-conductivity to a high electrical charge. Feed means are provided to index a predetermined length of matting to the respective clearance spaces between each pair of plates to test spaced portions of a mat. Take-up means are provided at the end of the feed means for wind-up of the mat material.
