Abstract: Method for obtaining information about friction between a heated glass gob and at least one guiding trough through which the glass gob is transported to a mould for forming a glass product from the glass gob using the mould, wherein the glass product is manufactured by: a. forming the heated glass gob; b. transporting the glass gob through at least one guiding trough to the mould; c. forming the glass gob into the glass product using the mould, wherein the method furthermore comprises the following steps: d. making an infrared image of an outer part surface of the at least one guiding trough along which, in use, the gob (while making contact with the outer part surface) is transported; and e. analysing the image for obtaining the information about the friction between the heated glass gob and the outer part surface of the at least one guiding trough along which the glass gob while making contact with the outer part surface is transported.

Abstract: Method of filling a mold with a glass gob through an opening of the mold, for forming a glass product in the mold, by using a delivery system for delivering the glass gob to the opening of the mold. The delivery system has an inlet, an outlet, and guiding means for guiding the glass gob through the delivery system. The method includes observing the glass gob, at at least one moment and/or during at least one period after the glass gob has passed the inlet of the delivery system, by using an optical imaging device. The method includes determining a glass gob observation result that includes a glass gob velocity, for predicting a glass distribution of the glass product formed in the mold and/or for controlling a next glass gob.

Abstract: Method of filling a mould and system for filling a mould. Abstract Method of filling a mould (8) with a glass gob (10) through an opening (12) of the mould (8), for forming a glass product in the mould (8), by using a delivery system (14) for delivering the glass gob to the opening (12) of the mould (8). The delivery system (14) has an inlet (16), an outlet (18), and guiding means (20) for guiding the glass gob through the delivery system (14). The method includes observing the glass gob, at at least one moment and/or during at least one period after the glass gob has passed the inlet (16) of the delivery system (14), by using an optical imaging device (4). The method includes determining a glass gob observation result that includes a glass gob velocity, for predicting a glass distribution of the glass product formed in the mould (8) and/or for controlling a next glass gob.
