Abstract
A forming device has a die with at least one recess, a punch for forming the packaging material into the recess, and a hold-down device. The hold-down device and the die receive the packaging material between them in a holding region. The die and the hold-down device each have a bearing surface with at least one opening, which is in fluid communication with a fluid source. An aerostatic bearing is formed between the packaging material and the hold-down device and between the packaging material and the die.
Claims12
A forming device for forming at least one cup into a packaging material, wherein the forming device comprises:
- a die, which comprises at least one recess;
- a punch, which is configured to form the packaging material into the at least one recess of the die;
- and
- a hold-down device, wherein the hold-down device and the die are configured to receive the packaging material between them in a holding region that surrounds the at least one recess of the die;
- wherein the die has, in the holding region, a first bearing surface, which faces the hold-down device, and wherein the hold-down device has, in the holding region, a second bearing surface, which faces the die;
- wherein the first bearing surface has at least one first opening, wherein the at least one first opening is in fluid communication with a first fluid source, and/or the second bearing surface has at least one second opening, wherein the at least one second opening is in fluid communication with the first or a second fluid source;
- and
- wherein the first bearing surface has a plurality of first openings and the die comprises a first bearing component, which surrounds the at least one recess and comprises the first bearing surface, wherein the first bearing component is formed at least partially from a porous material which provides the plurality of first openings.
A packaging machine comprising a forming device for forming at least one cup into a packaging material, a filling device for filling the at least one cup with a product, and a closing device for closing the at least one filled cup, wherein the forming device comprises:
- a die, which comprises at least one recess;
- a punch, which is configured to form the packaging material into the at least one recess of the die;
- and
- a hold-down device, wherein the hold-down device and the die are configured to receive the packaging material between them in a holding region that surrounds the at least one recess of the die;
- wherein the die has, in the holding region, a first bearing surface, which faces the hold-down device, and the hold-down device has, in the holding region, a second bearing surface, which faces the die;
- wherein the first bearing surface has at least one first opening, wherein the at least one first opening is in fluid communication with a first fluid source, and/or the second bearing surface has at least one second opening, wherein the at least one second opening is in fluid communication with the first or a second fluid source;
- and
- wherein the second bearing surface has a plurality of second openings and the hold-down device comprises a second bearing component, which surrounds the punch and comprises the second bearing surface, wherein the second bearing component is formed at least partially from a porous material which provides the plurality of second openings.
