Description: |
| The innovation here is a means of preventing the buildup of pitch on the feed-rolls. "My invention consists in making the size of the back-pressure feed-roll or rolls, or the size of the gear-wheel which drives them, so as to give the surface of the roll or rolls a greater or less motion than the front feed-rolls and lumber to be planed, thus causing the back roll rolls to slip a trifle on the planed surface, and thereby preventing any accumulation on the rolls, to cause indentations in the planed wood." |
