1. A method of calibrating a label vacuum-grip cylinder, the label vacuum-grip cylinder including adjustable suction strips, the method comprising:
rotatably attaching the label vacuum-grip cylinder to a support with the label vacuum-grip cylinder having an axis of rotation;
positioning an indicator holder support shaft adjacent a periphery of the label vacuum-grip cylinder, the indicator holder support shaft extending vertically in a position substantially parallel to the axis of rotation of the label vacuum-grip cylinder;
vertically positioning an indicator support holder on the indicator holder support shaft and fixing the indicator support holder in a selected vertical position on the indicator holder support shaft;
positioning a first indicator and a second indicator with the indicator support holder, the indicator support holder supporting the first indicator and the second indicator, the first indicator having a first display face with a first display and the second indicator having a second display face with a second display, a first projection area of the first display face of the first indicator projecting perpendicularly from the first display face, and a second projection area of the second display face of the second indicator projecting perpendicularly from the second display face;
wherein the indicator support holder supports the first indicator and the second indicator such that the first projection area and the second projection area do not overlap and neither the first indicator nor the second indicator obscures either the first display or the second display;
rotating the label vacuum-grip cylinder and measuring positions of at least one of the adjustable suction strips with the first indicator and the second indicator by having the at least one of the adjustable suction strips abut a first probe of the first indicator and a second probe of the second indicator; and
adjusting a position of the at least one of the adjustable suction strips based on the positions of the at least one of the adjustable suction strips measured during the step of rotating the label vacuum-grip cylinder and measuring positions of at least one of the adjustable suction strips with the first indicator and the second indicator; wherein the indicator support holder includes an upper indicator support area supporting the second indicator, a lower indicator support area supporting the first indicator at a location which is horizontally offset from said upper indicator support area, and a pole connection area for connecting the indicator support holder to the indicator holder support shaft, wherein the upper indicator support area, the lower indicator support area and the pole connection area are integral.
