T-FLEX Coders are rugged in construction, very simple to operate, give no down-time problems, and mark with sharp clear imprints. The extremely flexible and easily replaceable T-FLEX type flexes and prints sharp impressions on irregular or lapped surfaces. Printing is detailed even on unsupported lightweight boxes or containers. The Model 125 supports 5/16″, 1/2″, 5/8″, 3/4″ and 1/8″ type height and comes in either Random or Index designs. This model also has available an optional 2 or 3 Line types as well. Random: Random Coders work by rotating whenever a box comes into contact with it. Random Coders guarantee the type will be printed on the product only the random coder does not print in the same place on the product every time. Index: Index Coders work by resetting the coder placement after every product is run through. This guarantees every product will be printed on every time in the same place.
