Abstract: A device useable with a pellet-marking machine for inverting a multiplicity of pellets is disclosed. Pellets are transported in cavities on carrier bars mounted on a conveyor. The carrier bars move with relation to one or more rails disposed beneath the cavities and oriented transversely to the carrier bars. Each rail has a pellet supporting surface region arranged in tandem with a trough, followed by an inclined surface, followed in turn by a second pellet supporting surface region. Initially, each pellet is partially supported on a cavity bottom and partially on an associated pellet supporting surface region. As the carrier bars pass along the rails over the troughs, each pellet tips downwardly into a respective trough, flipping past the vertical. Each pellet next encounters the inclined surface following the trough, where each pellet is fully inverted while being moved upwardly out of the trough, to be supported on the second pellet supporting surface region following each inclined surface.

Abstract: A flat embossing machine for flat material (5) to be embossed has a flat press (2), an embossing table (3) and a tool plate (4). At least one foil web (6) passes through foil loop stores (10, 20) each with a differential pressure device (30) for shaping a foil loop (12) with an air pressure difference exerted on the foil web. A foil feed device (24) and a tensioning device (25) are on each side of the flat press and a foil feed control (52) operates in synchronism with the press cycle so that the foil web is stopped during the embossing phase (TP) on the embossing table (3) and is advanced to the next embossing position during the embossing-free phase. Speed differences between the feed speed (VV) at the embossing location and web speed (V7) at the unwinding roll or at the removal device (V8) are compensated for by corresponding increases and decreases in the size of the loops (L1, L2) in the foil stores. This allows high embossing speeds with optimum quality.

Abstract: The present invention provides a method and an apparatus for driving and controlling a thermal head used in a printing device, such as a tape printer, in response to the temperature variations of the printing device environment and the thermal head. According to the present invention, in the printing operation of the tape printer, measurements are made of the initial temperature T1 immediately after the power is switched on, the temperature prior to printing T2, and the ambient temperature of the thermal head each time the thermal head prints T3(i). If the temperature difference between the initial temperature T1 and the temperature prior to printing T2 is small, the duration of the current signals provided to the thermal head is controlled in accordance with the temperature prior to printing T2, which is the most recently measured thermal head ambient temperature best reflecting the printing device environmental temperature.
