16 of the filling pipe 15 in the nozzle 14 the caramel product 2 which is emitted from the nozzle 14 receives a hollow shape a viscous filling product 3 which is processed in the tempering and filling apparatus 17 and preheated to a temperature which is only slightly less than that of the caramel compound in the nozzle 14 is injected through the filling pipe 15 into the cavity in the jacket like product 2 the product 2 leaving the nozzle 14 and arriving at the guide 20 has a temperature of approximately 80 u00b0 c and is highly plastic the strand 2 moves obliquely downward on the rollers 22 of the guide 20 which has a relatively steep gradient toward the feeder roller pair 27 as a consequence of its own weight and because of the plastic consistency of the hot caramel compound the caramel product 2 stretches or is drawn along the gradient of the guide 20 causing its diameter to be decreased continuously down to approximately 15 mm during this process the wall of the caramel product 2 is thinned as the molecules making up the caramel compound become axially oriented and the cross section of the filling is reduced somewhat as well the degree to.
