<p>An apparatus for applying a printing or cutting force to an elongated strip of tape comprises a base (14) for supporting the strip (30) and a printing or cutting chip (29) in an aligned manner. A wedge-shaped force exerting element (15) has a curved force exerting surface (25) for engagement with the printing or cutting chip (29). The element (25) is supported in a pair of parallel, upwardly extending side walls (11 and 12) of the base (14). Rollers (35) pivoted to the force exerting element (15) to rotate about the axis of curvature of the force exerting surface (25) engage guide slots (18) provided in each of the side walls (11 and 12) and extending parallel to the plane of the base (14) which supports the strip (30) and the chip (29). Guide pins (34) also provided on the force exerting element (15) engage further slots in the side walls (11 and 12), each of these further slots having a first section 19 extending parallel to the slot (18), and a second section (20) extending at an angle downwardly towards the base (14). When the force exerting element (15) is operated by its handle (22), it will move from a rest position, in which the force exerting surface (25) is spaced from the chip (29), to an operating position in which the surface (25) exerts a force on the chip (29) to carry out the cutting or printing. During this movement the pins (34) will travel along the first section (19) of the further slot and then along the inclined second section (20) thereof, and during this latter travel, the force exerting element (15) will be tilted about the axis of the rollers (35) so that the surface (25) will perform a rolling, force exerting movementto transfer a printing or cutting force from the chip (29) to the strip of tape (30).</p> |
