Apparatus operable in accordance with the method of the present invention is provided for automatically controlling the operation of a de-air/tacker machine used in the manufacture of safety glass laminates to remove air from and promote bonding within the laminates. The machine comprises pinch rolls mounted to a carriage which is in turn mounted for rotational movement about a generally horizontal axis relative to a support frame. The pinch rolls define a pressure nip through which the laminates pass to be processed. A motor is connected to the carriage for rotating the carriage, and hence the pinch rolls, about the generally horizontal axis and a digital encoder is provided for sensing rotational operating movement of the motor. A computer is connected to the motor and the encoder for operating the motor in accordance with a predefined sequence for each laminate which is processed such that the carriage is positioned to maintain the pinch rolls substantially normal to the laminates which are therefore balanced within the pinch rolls as the laminates are passed through the machine to thereby prevent breakage of glass templates of the laminates. An operator of the machine can rapidly select one of a number of stored programs to control the carriage for the production of corresponding laminates or can define a new program as necessary for new laminate designs or to customize operation in accordance with the skill and experience of the operator. |
