BAND SAW RIG FOR SAWING LENGTHWISE

摘要

The invention pertains to band saw rigs for sawing timber lengthwise, with horizontally directed band saws and intended for use in cutting timber into beams, planks etc. The problem addressed by the present invention is that of designing a band saw rig of simple design and requiring little labour to manufacture while eliminating flaws in geometry in the timber produce. This is achieved in the following way: in a band saw rig with two guide pillars (1, 2) connected by frames (3, 4), on which pillars a saw mechanism (7) is mounted via support elements (5, 6), and a device including a drive for displacing the saw mechanism vertically, the vertical displacement device is provided with two links (11, 13) connected by an articulating joint. One of the links (11) is connected by an articulating joint to the upper frame (3) of the pillars and the second (13) is similarly connected to the saw mechanism (7). The axes (12, 14, 15) of these articulations are parallel to one another and perpendicular to the guide pillars.
