Abstract: A device is provided for shrinking shrinkable packages by heating by utilizing a liquid and/or gaseous heating medium, which reduces the amount of energy required. The novel device and method achieves its advantages by recovering heat by a recirculation apparatus (8, 9) for recovering heating medium which has evaporated from the liquid heating medium. The method relates to an operational process utilizing such a device.

Abstract: A packaging machine and a method for the production of packages by the packing of material in packages, with a machine having at least one processing station, such as a sealing station, a cutting station or similar station and a weighing station (8) for determination of the weight of the filled and sealed packages (7), is provided which has less space requirements than conventional packaging machines and improved manipulation. According to the invention, the above is achieved, whereby the weighing station (8) and/or the at least one processing station has a controller, in which the working speed of the weighing station (8) is synchronized with the working speed of the previous processing station.

Abstract: A packaging machine with at least one pneumatic drive is proposed, which packaging machine is insensitive to dirt and is easy to clean. According to the invention, this is achieved by provision of an integrated structural unit (8, 9, 10) which comprises a pilot valve and a pneumatic cylinder.

Abstract: Proposed are a weighing device for a packaging machine and a method for weighing packages from a packaging machine, which can be realized in a space-saving manner and/or permit the processing of packages within a large spectrum of package formats. This is achieved according to the invention in that the weight of two or more packages (7?, 7?) and the weight which is changed as a result of the subsequent supply or lead-away of an individual package (7?) or of a number of packages which are to be weighed together are measured, with it being possible for the weight of an individual package (7?) or of a number of packages which are to be weighed together to be determined from the difference between the weights which are determined in this way.
