Abstract: An ink roller assembly for attachment to a tape printer or the like includes a pre-inked roller rotatably mounted between a pair of hanger brackets of substantially greater diameter and capacity than the standard pre-inked roller included with the machine. The hanger brackets are adapted to mount to an eccentric shaft which can be rotated to finely adjust the pressure of the ink roller against the print wheel. Several cross shafts extend between the hanger brackets to provide support with one of the cross shafts having a threaded hole therein for insertion of a threaded screw against the frame of the machine to adjust the pressure of the over-sized ink roller against the print wheel.

Abstract: A liner-separating tape-feeding machine that automatically feeds pressure-sensitive tape from a supply roll, peels the liner off the tape, delivering the tape in one direction and the liner in another and separating the tape into predetermined lengths. The liner is peeled from the tape by being brought around an edge at an acute angle from the tape, while it is kept under tension by having its feed roller move at a greater peripheral speed than the feed roller for the unseparated tape. Means are provided for optional delivery of a selected length of tape each time a previous piece of tape is removed from the machine.

Abstract: A plastic, heated water tank for gummed tape dispensing machines that resists corrosion, is easy to clean, reduces the likelihood of burning the user, and yet affords good heat transfer from an external heating element into the water in the tank. It provides as an insert in the plastic tank a tubular metal heat transmission member with special sealing means between the plastic and the ends of the metal member. The sealing means prevent leakage from the container around the ends of the metal member that could result from differences in expansion rates of the plastic and the metal.
