摘要：<p>The safety device is applied to a vertical type, wood shearing or veneer cutting machine, and prevents the blade-holding unit and the bar-carrying unit from striking the hooks of the wood supporting table, during the shearing process. The safety device comprises a set of magnetic proximity switches, placed on the bar-carrying unit near and above the cutting point, equally spaced from each other and opposed to respective hooks or dogs fixed to the wood supporting table. The hooks are also equally spaced and are alternatively of greater and smaller length, so that the upward and downward vertical motion of the wood stock is stopped when the magnetic switches near the hooks of greater length and operation of the machine is stopped so that the hooks or dogs can be replaced by others of smaller length.</p>
