Procedure for the production and/or treatment and development of an endless material made of thermopastic plastic with a quality signal and recording device

摘要

In such a process in which a quality signal Q is output as a function of a continuously measured process parameter, one selects a parameter of state of the forming package (33) as an indicative process parameter, one acquires same, a value derived therefrom, or the value varying with respect to time during the entire winding cycle of the formed packages (33), and one compares the values with a predetermined representative value or its tolerance range, so as to release a quality signal in the event of an undue deviation of the parameter of state or the derived value from the desired value. This [signal] may used to cause an alarm, to classify the production results of the continuously produced packages (33) and/or intervene in the process control, so as to counteract the detected deviations or tendencies to such deviations. To carry out the method, a suitable sensor winding head is described, which enables a continuous determination of the weight of packages (33) during the winding cycle. IMAGE
