    摘要： A blank locating device for use with machines having a vertically reciprocable working member designed to register blanks below the working member against fixed rearward positioning stops. The device includes a mounting bracket which is carried on a side of the working member, an arm pivotable on the mounting bracket about a horizontal axis, and a downwardly extending rod which is supported by and vertically slidable within the arm. The rod has at its lowermost end a vacuum cup or other means for engaging the blanks while the working member and rod thereon are in downward motion but still above the blanks. After engagement with a blank, downward movement of the rod stops, and a cam surface on the rod contacts a cooperating surface on the still moving working member as the latter continues in its downward direction. This relative movement of the working member and rod forces the rod lowermost end rearwardly, the length of the rearward positioning stroke depending upon the shape of the cam. Also provided to change the rearward stroke is an adjustment which varies the normal inclination of the rod and thus the starting point for the stroke. The device further includes a third adjusting means for varying the pressure with which the rod engages the blank.
