Roll Markers - Mark 25S

Instructions for setting up Roll-A-Matic 25S

MARK 25S - A new and different design that accepts 3/4" x 5 1/2" long legends and still retains the single rotation positive lock features. (see diagram)

The Mark 25S shall be mounted in the acceptable tool holder WITHOUT THE WORK ROTATING. The slide is brought in so that the cam rise of the marking roll touches the work. WORK MUST NOT ROTATE. Apply between .002 and .004 pressure to the cam rise of the roll against the work back tool away, start machine, and bring holder and roll in contact with the work. At this point, the cam on the roller should engage against the work, causing the roll to rotate and imprint the work. If the mark made by the roller is too shallow, push the arbor shaft out only far enough to the splines. Rotate the roll one or two notches in the direction that will cause the cam to contact the work closer to the beginning of the cam rise. (Depth of impression will change. It is necessary to go through the first procedure again, for now there will not be enough pressure between the work and cam to start roll rotating or so much pressure it may cause roll to jam or slip, depending upon which way you rotate).

If the impression is too deep, rotate the roll in a direction that will cause the cam to turn toward the work, thereby making the roll contact the work closer to the engraved lettering.

SYNOPSIS - The closer to the cam you start to the lettering, the less pressure you will exert between the roll and the piece you are marking, the shallower the impression depth. The closer to the beginning of the cam you start, further from the lettering, the more pressure you exert between the roll and the piece you are marking, therefore giving you a deeper impression.

The shaft of the roller should be on the same centerline as the work or as much as ¹/₆₄" below the center, but this is maximum.
