PURPOSE:To enable smooth conveying stroke by pressing a driving arm connected to a feed bar to a cam at all times and preventing generation of chatter and oscillation. CONSTITUTION:When a driving pinion is driven, a cam 4 turns. A cam follower 7 which is kept pressed by a cylinder 9 is moved along the cam surface by turning of the cam 4 by which a driving cam 6 is oscillated. A feed bar connected to the top end of the arm 6 is moved back and forth in the feed direction. |
