Abstract
Apparatus for fluting corrugated board or solid board includes a first sonotrode and an anvil or a second sonotrode disposed opposition to the first sonotrode. A local zone of the solid board or layers of the corrugated board is compressed between the first sonotrode and the anvil or second sonotrode, and then subjected to ultrasound to form a flute line or crease in the corrugated board or solid board.
Claims19
Apparatus for fluting corrugated board or solid board, comprising:
- a first sonotrode;
- and
- a member placed in opposition to the first sonotrode and selected from the group consisting of an anvil and a second sonotrode.
A method, comprising the steps of:
- compressing a local zone of a solid board or layers of a corrugated board between a first sonotrode and a member selected from the group consisting of an anvil and a second sonotrode;
- and
- subjecting the local zone to ultrasound.
A computer program embodied in a non-transitory computer readable medium, wherein the computer program, when loaded into the processing device and executed by the processing device, causes the processing device to perform the steps of:
- compressing a local zone of a solid board or layers of a corrugated board between a first sonotrode and a member selected from the group consisting of an anvil and a second sonotrode;
- and
- subjecting the local zone to ultrasound.
A control device for an apparatus for fluting corrugated board, said control device being constructed to execute perform the steps of:
- compressing a local zone of a solid board or layers of a corrugated board between a first sonotrode and a member selected from the group consisting of an anvil and a second sonotrode;
- and
- subjecting the local zone to ultrasound.
