Abstract: The glass machine comprises: a camera assembly (8) having a first thermal camera (9) that is movable on a preform side of the glass machine above a preform (3) and/or parallelly movable to a drop incidence direction in which a glass drop (4) occurs into the preforms; an adjusting device for a gutter system of the glass machine; and a cooling controller for controlling and/or regulating the preforms. The camera assembly has a second thermal camera (10), which is inclined to the first thermal camera and whose longitudinal or optical axis forms an angle with the drop incidence direction. The glass machine comprises: a camera assembly (8) having a first thermal camera (9) that is movable on a preform side of the glass machine above a preform (3) and/or parallelly movable to a drop incidence direction in which a glass drop occurs into the preforms; an adjusting device for a gutter system of the glass machine; and a cooling controller for controlling and/or regulating the preforms. The camera assembly has a second thermal camera (10), which is inclined to the first thermal camera and whose longitudinal or optical axis forms an angle with the drop incidence direction. The second thermal camera is set on a different wavelength range from the first thermal camera so that a three-dimensional image of the incident glass gobs is detected using the thermal cameras, where a surface temperature of the glass drop is detected by the first thermal camera and a temperature inside the glass drop is detected by the second thermal camera. The first thermal camera of the camera assembly is adjustable at its alignment and/or parallel to the drop incidence direction in an inclined position. The second thermal camera of the camera assembly from a position is provided in which longitudinal- and/or optical-axis forms an angle with the drop incidence direction, is adjustable in the position, and is aligned in and/or parallel to the drop incidence direction. The camera assembly comprises: a first measuring position in which the first and second thermal cameras are symmetrically arranged to one another with respect to the drop incidence direction and form with its longitudinal- and/or optical-axis of the angle with the drop incidence direction; and a second measuring position in which the first and second thermal cameras with same distance and its longitudinal- and/or optical-axis are parallelly arranged to the drop incidence direction. The glass machine is ascertainable and/or measurable by the camera assembly at each station of the glass machine up to four preform, mouth shapes, glass blanks and/or -parison and level and the glass drop associated with the respective preforms. The gutter system as a function of value determined in a computing unit and a control unit for the mass is adjustable to an incidence angle and an incidence point of the glass droplets. The cooling controller of the preforms as a function of value determined into the computing unit and control unit is adjustable for the temperature of the preform and/or preform couples, the mouth shapes, the glass blanks and/or -parison, the level and/or the glass drop. The thermal cameras are formed as infrared cameras. The camera assembly is mounted at a carriage sled, which is moved back and forth on a linear axis along a preform side of the glass machine.
