发明名称 VERFAHREN ZUM ÜBERWACHEN DER QUERSCHWEISSUNGEN IN EINER VERPACKUNGSEINHEIT ZUM KONTINUIERLICHEN FORMEN VON VERPACKUNGEN MIT FLÜSSIGEN NAHRUNGSMITTELN SOWIE VERPACKUNGSEINHEIT
摘要 The method is aimed at indirectly determining the energy absorbed by a conducting layer (5) forming part of a strip of packaging material (1) to be sealed transversely. The method is based on measuring parameters correlated with the power supplied by a current source (45) to the packaging material (1) during sealing, and with the temperature of the conducting layer (5). The temperature measurement takes into account the temperature of the product to be packed, the characteristics of the packaging material, and the characteristics of the mechanical sealing members; correct cutting of the packaging material after sealing is also determined; and the parameters are monitored by measuring associated quantities and by comparison with permissible values. <IMAGE> <IMAGE>
