ABSTRACT:
A rubbing machine of the type in which a support is spaced from and overlies a rubbing shoe and in which the rubbing shoe is connected to the support by a drive mechanism operable to reciprocate the shoe. The rubbing shoe is rectangular in shape with the drive mechanism connected at the center of the shoe, and four flexible boots are connected between the support and the shoe at the corners of the shoe. Four pair of opposed, rigid studs are mounted between the support and the shoe to transmit thrust therebetween, and each pair of studs is mounted within a respective one of the boots with one of the studs connected to the support and one to the shoe. A tongue-and-groove connection between the opposing ends of each pair of studs confines the shoe for linear reciprocation in a straight path.
