FIELD: wood working. SUBSTANCE: housing provided with spring- loaded lever whereon a pressing roller is mounted is fixed in the vertical direction in a guide provided with marks. When the roller is in a contact with the surface of a part the top portion of the housing is coincident with marks required thus providing a constant pressing force. The housing is wedged by an eccentric in the guide. There is a stop on the housing that arrests rotation of the lever together with the roller within no more than 10-15 deg to the vertical axis of the housing in the direction of supply. As a result, when a part moves back it is wedged. EFFECT: simplified design and enhanced reliability. |
