Abstract
In a method for the manufacture of prismatic or truncated-pyramid-shaped beams, it is suggested to produce respectively two adjoining, mutually perpendicularly disposed lateral faces in one working step by simultaneous edging. In an apparatus for performing the method of this invention, a machining tool (2) with two sawing or cutting tools (7, 18) is provided, these last-mentioned tools forming a right angle with each other and being arranged offset with respect to each other in the direction of the longitudinal extension of the bole (6) to be edged.
Claims8
A three-step method for the manufacture of beams of truncated pyramidal cross section enclosed by four flat sides that are perpendicular to each other but spaced apart, comprising positioning a bole on a support, forming two said sides at right angles to each other simultaneously, turning the bole 180.degree. on the support, and forming the other two sides simultaneously.
Apparatus for the manufacture of beams from boles, comprising a holder on which a said bole rests stationary, said holder having stationary bole-supporting surfaces disposed at right angles to each other, a pair of tools having working faces for forming on a bole flat surfaces disposed at right angles to each other, said working faces being respectively parallel to said supporting surfaces, means for moving said tools and said holder toward and away from each other, means mounting said pair of tools on a common support, and means mounting said support for horizontal movement relative to said holder in a direction parallel to the length of a said bole on said holder.
