Abstract: A paper web threading apparatus is provided for a papermaking machine. The threading apparatus includes a transfer sheave assembly mounted on an end of a middle rotating drum disposed between an upstream drum and a downstream drum. The transfer sheave assembly includes a first sheave that is fixed to the middle drum and rotates with the middle drum and a second sheave that rotates freely and independently of the middle drum. An upstream pair of endless ropes is provided that wrap partially around the sheave of the upstream drum before wrapping partially around one of the sheaves of the transfer sheave assembly. A pair of downstream endless ropes is also provided that wrap partially around the other of the sheaves of the transfer sheave assembly as well as the sheave mounted to the downstream drum. The upstream ropes maintain an adjacent position with respect to each other until they depart from the transfer sheave assembly.

Abstract: An apparatus and method for measuring torque imposed on a drive shaft and horsepower transmitted to a drive shaft are provided. The apparatus includes four strain gauges mounted onto the drive shaft. The strain gauges are connected to a transmitter which is accommodated within a rotating collar mounted onto the drive shaft. The changes in resistances of the strain gauges are then transmitted by the transmitter to a receiver. Strain level is then calculated from the measurement of the changes in resistivity and torque may be calculated from the strain level calculation. A means for measuring rpm or rotational velocity is provided which, in combination with the torque calculation, results in a means for calculating the power transmitted to the drive shaft.
