Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to planing machines, particularly portal planers.

[Conventional technology] Conventionally, this type of planing machine has been equipped with upright gateposts on both sides of a processing table that moves reciprocally on the machine table.
