ABSTRACT:
A flat belt type testing apparatus for measuring the cornering characteristics of a tire has a pair of rotatable drums around which an endless steel belt is stretched. A tire is supported on the endless steel belt by water jets ejected from a water bearing equipped below the endless steel belt. Waterdrops attached to the reverse side of the endless steel belt are removed by a rear wiper pressed against the endless steel belt downstream of the water bearing. An air blower mechanism placed between the water bearing and the rear wiper includes at least one air pipe having air jet holes for ejecting air under high pressure against the reverse side of the endless steel belt to remove waterdrops from the endless steel belt. Since water can completely be removed from the endless steel belt by the air blower mechanism and the wiper, the drums are free from rust, and a centering sensor equipped close to the endless steel belt is not subjected to a detection failure due to getting wet with water.
