Abstract: The invention relates to a method to control the temperature for sealing devices used in the packaging industry which sealing devices are provided with electrically heated elements made of temperature dependent resistance material. The electrical current is divided in pulses whereby the length of the pulses is adjusted by means of a controlled switch (6). During the interruptions between the said current pulses, separate measuring current pulses of a constant and known value are generated which pulses will cause an electric voltage drop over the resistance element (2). Said voltage drop will be proportional to the temperature of the resistance element. The voltage drop will in a regulator (7) be compared with a set potential corresponding to a desired temperature whereby the sensed potential difference between the voltage drop measured and the set potential value is adapted to control a driving device (9) which will control the length of the heat generating current pulses.

Abstract: The invention relates to a method and an apparatus for the supply of a gas or a gas mixture at a predetermined temperature to a processing station in a filling machine in which gas or gas mixture pressurised to above atmospheric is passed through an electrically heated heating unit (2, 3; 6, 7). This includes a sensor sensing the temperature of the gas whose output signal is fed back to a gas temperature regulator unit (not shown) which in its turn is coupled to the heating unit with a view to regulating the temperature of the gas flowing out from the heating unit (2, 3; 6, 7). The heating unit (7) is formed to an electrically conductive shell or a cavity (6) through which the gas or gas mixture is passed positively and regulated. In such instance, the shell (7) is coupled to a voltage regulated via a regulator unit in an electric current circuit, as a result of the current which is driven by the circuit and as a consequence of the resistance of the material, the shell being heated up and thereby the gas and the gas mixture, whereafter the temperature in the shell is registered and fed back to the regulator unit which regulates the voltage against a gas temperature which corresponds to that which is desired to flow out from the shell or the cavity (6).

Abstract: The present invention relates to a method relating to a start-stop cycle of a packaging machine in handling a thin "non-spring-back" tubular packaging material web fed from a roller, the packaging material having a weight so low that when such a cycle is initiated from an arbitrary starting point, the packaging material, introduced or situated between transversal heat-sealing jaws of said machine, tends to stick to said jaws. The method is characterized by the step of passing a portion of the web, being longer than at least the length of one package, past the jaws, the packaging material being without content, whereby the weight of bypassed packaging material makes the packaging material self-releasing from the jaws during initial start-up.
