Downstream guide for peeling machine

In a peeling machine through which a rod workpiece is moved along a workpiece axis and having upstream and downstream guides centering the workpiece on the axis and axially flanking a rotary scraper engaging the workpiece and carried on an upstream end of a scraper tube coaxially surrounding the downstream guide and rotatable about the workpiece axis, the improvement wherein the downstream guide comprises:

• a stationary tubular housing extending coaxially in the rotatable scraper tube and formed around the axis with a plurality of downstream-flaring seats;
• a plurality of shafts pivotal in the tubular housing about respective guide axes angularly spaced about the workpiece axis and having upstream-tapering upstream ends engageable in the respective seats
• respective axially elongated guide bars fixed on the shafts, extending axially therealong generally a full length of the scraper tube, and projecting radially of the guide axes therefrom;
• hydraulic means on the downstream guide for pressing the upstream shaft ends upstream into the respective seats and thereby locking angular position of the shafts and guide bars relative to the guide axes;
• and
• guide elements carried on the bars and radially engageable of the workpiece axis with the workpiece.
