Method and System for Producing Glassware

A method for producing glassware comprising the steps of:

• rotating a glass intermediate with a receptacle rotational speed about a receptacle rotational axis;
• rotating at least one forming roller with a roller rotational speed about a roller rotational axis;
• and
• displacing the at least one forming roller and the glass intermediate into a forming roller contact.

A method for producing rotationally symmetrical glassware comprising the steps of:

• forming at least one glass intermediate in at least one pre-forming step in which the at least one glass intermediate is rotated by a pre-forming rotational speed for shaping in a forming roller contact with at least one forming roller;
• and
• forming the at least one glass intermediate in a final forming step, in which the at least one glass intermediate is rotated for shaping in a forming roller contact with a forming roller by a final forming rotational speed;
• wherein the final forming rotational speed is greater or less than the pre-forming rotational speed.

A device for forming a rotating glass intermediate, said device comprising:

• at least one forming roller, which is rotatable about a roller rotational axis for shaping in a forming roller contact with the glass intermediate;
• and
• at least one roller motor for rotating the at least one forming roller about the roller rotational axis,
• wherein the at least one roller motor is a servomotor.

A system for producing glassware, said system comprising:

• at least one receptacle for rotatably holding a glass intermediate;
• at least one receptacle motor for rotating the receptacle about a receptacle rotary axis;
• and
• at least one device comprising at least one forming roller, which is rotatable about a roller rotational axis for shaping in a forming roller contact with the glass intermediate, and with at least one roller motor for rotating the at least one forming roller about the roller rotational axis,
• wherein the at least one roller motor and/or the at least one receptacle motor is a servomotor.

A system for producing glassware, said system comprising:

• at least one receptacle for rotatably holding a glass intermediate;
• at least one pre-forming device comprising at least one forming roller for shaping in a forming roller contact with the glass intermediate;
• a final forming device comprising at least one forming roller for shaping in a forming roller contact with the glass intermediate;
• and
• a feed device for moving the at least one receptacle from the at least one pre-forming device to the final forming device.
