Address and Numbering
A 5.0 mm high numerator is used for all sizes of bands, but this numerator has a maximum of five characters (e.g. AB001). However, a greater number of characters can be applied by breaking the number into a prefix and number (e.g. ABC00001), and carrying out two separate stamping operations. As the number is always applied to the side of the band that is on the outside of the flipper, this usually means that the prefix and number sit either side of the join when closed. As the band is egg-shaped and the number needs to be field-readable, the bands have to be made either to fit the right or left flipper. If there is a preference, the customer must specify that preference on the order.
Although a few customers require just a simple number to be stamped on the bands, most also require an address. As the bands are large there is plenty of room for a detailed address, but a three-line address each of 24 characters should be considered as the maximum. The manufacture of address dies has to be subcontracted to a specialist engraving company but a quotation for the cost of producing these dies can be obtained on request. The dies are retained at the factory for future orders.
