Abstract
Cross Seal Devices and related methods are provided. A cross seal device for forming ends of packages being formed in a packaging forming system can include an anvil configured to extend transverse to a product pathway of a packaging forming system along which top and bottom sheet materials travel. The cross seal device can also include a track positioned above the anvil transverse to the product pathway. Further, the cross seal device can include a carriage configured to operate along the track. The carriage can include one or more rollers configured to engage the anvil to form a pressure contact between the anvil and the roller so that the top and bottom sheet materials are joined together.
Claims23
A cross seal device for forming ends of packages being formed in a packaging forming system, the cross seal, device comprising:
- an anvil configured to extend transverse to a product pathway of a packaging forming system along which top and bottom sheet materials travel;
- a track positioned above the anvil transverse to the product pathway;
- and
- a carriage configured to operate along the track, the carriage comprising one or more rollers configured to engage the anvil as the carriage moves transversely across the product pathway to form a pressure contact between the anvil and the one or more rollers so that the top and bottom sheet materials are joined together to form a transverse cross sear across the product pathway, and the carriage comprising one or more blades that move transversely across the product pathway with the carriage to cut the joined top and bottom sheet materials to form the ends of the respective adjacent packages being formed in the system.
A cross seal device for forming ends of packages being formed in a packaging forming system, the cross seal device comprising:
- an anvil configured to extend transverse to a product pathway of a packaging forming system along which top and bottom sheet materials travel;
- a track positioned above the anvil transverse to the product pathway;
- and
- a carriage configured to operate along the track, the carriage comprising one or more rollers configured to engage the anvil as the carriage moves transversely across the product pathway to form a pressure contact between the anvil and the one or more rollers so that the top and bottom sheet materials are joined together to form a transverse cross seal across the product;
- and
- the anvil comprising cam surfaces on either side of the anvil where the one or more rollers reside when the carriage is at rest on either side of the product pathway.
A method for forming ends of packages being formed in a packaging forming system using a cross seal device, the method comprising:
- providing a cross seal device comprising:
- an anvil configured to extend transverse to a product pathway of a packaging forming system along which top and bottom sheet materials travel;
- a track positioned above the anvil transverse to the product pathway;
- and
- a carriage configured to operate along the track, the carriage comprising one or more rollers and the carriage comprising one or more blades that move transversely across the product pathway with the carriage to cut the joined top and bottom sheet materials to form the ends of the respective adjacent packages being formed in the system;
- feeding a top sheet material and a bottom sheet material used to form a package around, a product between the anvil of the cross seal device and the track;
- engaging the anvil with the carriage to form a pressure contact between the anvil and the roller;
- and
- running the carriage along the track transversely across the product pathway so that the rollers are under pressure against the anvil roll over the top and bottom sheet materials to joined together the top and bottom sheet materials to form a transverse cross seal across the product pathway;
- and
- cutting the joined top and bottom sheet materials with a blade of the one or more blades attached to the carriage as the blade and the carriage move transversely across the product pathway to form the ends of the respective adjacent packages being formed in the system.
