<p>A lathe having first and second support walls (12,16) that support pairs of vertical and elevated vertical guides (24,32,40,44), and having frames (52,54) that support horizontal guides (56,58). Trunnions (26,42) are mounted on the vertical guides and support a log peeling assembly (30). A structure supporting back-up powered rollers (36) is mounted on the elevated vertical guides (32,44). First and second spindle assemblies (60,62) are mounted on the horizontal guides for movement between a first working position where a log to be peeled is gripped and rotated, and a second working position where the log continues its rotation into a knife extending from the log peeling assembly (30) to produce veneer. When a predetermined log diameter is reached the first and second spindle assemblies release and return to the first working position to grip another log, while the log being rotated continues to be peeled until it reaches a minimum core diameter.</p> |
