CONTROL SYSTEM FOR AUTOMATIC ADJUSTMENT OF LATHE KNIFE PITCH

摘要

An electrical control system is described for automatic adjustment of the pitch angle of a lathe knife in a veneer lathe apparatus in response to reduction of the diameter of the log during peeling. The control system includes a digital computer having a memory in which are stored a plurality of data tables of different pitch angle profile ranges for different wood species. The lathe knife pitch angle is adjusted by such computer control system changing the height of a cam follower roller on a knife carriage which mopes along a mechanical pitch rail cam member during peeling.
