A means for quickly placing a roller set onto a supporting shaft is disclosed. Generally, a guide sleeve is mounted at one end of the shaft and formed whereby the upper surfaces of the sleeve provide an aligned continuation of the upper surface of the supporting shaft. The remaining portions of the sleeve surface taper inwardly away from the imaginary continuation of the shaft surface. Thus, the sleeve has a diameter somewhat less than the outer diameter of the supporting shaft and accordingly, less than the inner diameter of the roller set. This arrangement facilitates a slipping of the roller set onto the guide sleeve without a need for precisely aligning the roller set with respect to the guide sleeve. The configuration of the upper surfaces of the sleeve insures the proper alignment of the roller set with the supporting shaft. Once the roller set is placed onto the guide sleeve, it may then be easily slipped from the sleeve and onto the shaft. |
