There is disclosed a method of making a print head assembly and a print head assembly. The print head assembly is comprised of one or more subassemblies. Each subassembly is made up of relatively few parts including a mounting block having a concave mounting surface, a series of drive wheels supported at their outer peripheries on the mounting surface, and a series of printing bands with which the drive wheels are engaged. The subassemblies can be readily assembled on a fixture. Thereafter, each subassembly is oriented relative to side plates to make a print head assembly. |
