ABSTRACT:
An entry guide device comprising a funnel shaped inlet member in close proximity to three adjustable rollers mounted at 120.degree. around the axis of work moving through the entry guide device. The adjustable rollers are actuated to move in concert so as to be able to accommodate a work product of difference diameters, whilst preserving the concentricity of the three rollers. The funnel shaped inlet member is replaceable to accommodate for wear and provision is made to calibrate the position of the three movable rollers with a calibration device which may be conveniently inserted into the device to check and calibrate the three rollers for concentricity. This entry guide device is ideally suited for guiding a work produce having circular, triangular or hexagonal cross-sections.
