Disclosed are three embodiments of a hand-held apparatus for printing and applying pressure sensitive labels. All the embodiments are disclosed as having a housing, a rigid, metal, frame plate mounted by the housing, a platen and a cooperating print head, a delaminator for delaminating printed labels from the web of supporting material on which the labels are carried, an applicator for applying the printed labels, a feed wheel having teeth for engaging and advancing the web, a manually operable actuator drivingly connected to the feed wheel and the print head, a brake, and an ink roll for inking the print head. The apparatus also includes a feed wheel assembly having a feed wheel driven by a pawl and ratchet mechanism. The pawl and ratchet mechanism is adjustably connected to the feed wheel and a rolling contact type one-way clutch prevents loss of tension in the web between the brake and the feed wheel. In two of the embodiments the brake takes the form of a roll operated by the print head and in another embodiment the brake is operated by the printing head through an overcenter mechanism. The print head has a pair of ball tracks and the frame of the apparatus mounts a pair of ball tracks containing respective ball bearings. The feed wheel is driven by gear means having an eccentric adjustment. The web is guided through the apparatus by track structure which is readily assembled and removable. A delaminator of one embodiment includes a plurality of small diameter rollers mounted on a shaft. An inking mechanism includes an ink roll having hub sections, with an ink-tight seal between the hub sections. The frame plate is accurately located and reliably held to a housing section. A removable housing section is snap-locked into place relative to at least one other housing section. The labels which are carried on the web are mounted on an easy to manufacture, low cost reel. A rewinder is provided to rewind the spent portion of the supporting material web. An improved composite label web is also disclosed.
