A wrapping machine and a method for wrapping a plastic foil web around an object. Furthermore, a method is presented for producing an output signal from an input signal with a specific frequency, and for changing the frequency of the output signal quickly in steps of the size of an output frequency resolution or a multiple of the output frequency resolution, on the output frequency band. The timing device includes a timer for controlling the time periods during the normal operation cycle and during the cleaning cycle. A polyacetal resin stopper link, which holds and limits the linear position and the bending position by engagement with the connecting link module, is inter-fitted with a coupling portion of the connecting link module by a snap-fit mechanism from the cable accommodating space side. Further, the weights are assigned to each of the one or more attributes and a product rank is generated for each of the one or more products based on assigned weights and the score by using a predefined relevancy-ranking algorithm. The pin connections can be engaged or disengaged robotically or under direct operator control.
