PURPOSE:To cope with the high speed supply by containing a rectangular pup in a pull supply chute in one line in the lengthwise direction, so that the pull of the next position and thereafter for discharging the pull of the leading end is migrated smoothly toward the downstream and by dead weight. CONSTITUTION:A pull supply chute 6 has a chute groove 10 which contains a pull 9 by aligning it in one line in the lengthwise direction, and slides it down by dead weight, and is inclined toward the downstream end 7 from the upstream end. For instance, in the case a control projection of the pull formed, when the preceding pull 9 in a flat attitude in a pull guide groove 12 is advanced by a pull pusher 13, the projection of the preceding pull 9 presses down the lower face of the pull 9 of the next position but the pressure is absorbed by a spring material 19 for pressing elastically an abutting pin 14, and when the pull pusher 13 further advances, the projection of the preceding pull 9 is caught by a fitting hole of the pull 9 of the next position. When the pull pusher 13 is further advanced, the pull 9 of the next position is pushed upward gradually, the projection of the preceding pull 9 is detached from the fitting hole of the pull 9 of the next position, and the pull 9 of the next position occupies a prostrated attitude on the upper face of the pull pusher 13. |
