Claims15
A process for starting up a film production in a film manufacturing machine, wherein the film manufacturing machine is a blown film machine, by means of a control device, comprising the following steps:
- detecting a start-up request
- setting start-up parameters
- providing film material
- commencing the film production
- setting film production parameters.
A process for terminating a film production in a film manufacturing machine, wherein the film manufacturing machine is a blown film machine, by means of a control device, comprising the following steps:
- detecting a termination request
- adjusting termination parameters
- terminating the film production.
A blown film manufacturing machine, the blown film manufacturing machine comprising:
- at least one extruder for producing and providing molten plastic material,
- a die device from which the molten plastic material can be drawn in the form of a film,
- at least one transport roll,
- at least one winding device whereby the can be wound up, and
- at least one control device configured to issue control commands to:
- detect a start-up request;
- set start-up parameters;
- provide film material;
- commence the film production;
- and
- set film production parameters.
A computer program product comprising instructions which, when the program is executed on a control device comprising a computer, cause a film manufacturing machine to:
- detect a start-up request;
- set start-up parameters;
- provide film material;
- commence the film production;
- and
- set film production parameters.
