Carton Sealing Machines
Carton sealing machines are used to tape and seal individual cartons. They can generally be classified into two categories: Uniform (or Adjustable) and Random. Uniform carton sealers are ideal for sealing uniformly sized cartons. If you have different sized cartons, however, then Random carton sealers are ideal as they automatically detect the dimensions of each carton using sensors and adjust the tape head accordingly. Both these types of machines come in semi-automatic and automatic styles, with top and bottom or side belt drives.
Semi-Automatic Uniform Carton Sealers
Semi-automatic uniform sealers are the least automated option, as they require an operator to manually adjust the height and width of the machine for each carton size. The operator also folds the flaps of each carton down and feeds them into the machine. Ideal for applications where cartons of the same size need to be sealed at the same time.
Automatic Uniform Carton Sealers
Automatic uniform sealers automatically feed the cartons into the machine, fold the flaps of the carton and seal them. An operator is still required to manually adjust the height and width of the machine for different carton sizes. Ideal for applications where cartons of the same size need to be sealed at the same time.
Semi-Automatic Random Carton Sealers
Semi-automatic random sealers are perfect for those needing the flexibility of an automated solution where the machine will automatically adjust to the width and height of each carton. An operator is still required to fold the flaps and feed the cartons into the machine. Ideal for applications where cartons of different dimensions are to be sealed on the same shift.
Belt Drive Options
Carton sealing machines generally come with either a side belt drive or a top and bottom belt drive.
Side Belt Drive: Designed for use with cartons that are no longer in length and shorter in height. Contact with the carton is made on the lower part of each side. Moving side belts 'capture' the carton as it moves past upper and lower tape heads, and as such is ideal for preealing the bottoms of empty cartons prior to packing.
Side belt drive is the preferred method of processing narrow width cartons. This style will process a wide variety of carton dimensions but extremely heavy or extremely unstable cartons may be better suited to a sealer with top and bottom belt driver.
Top and bottom Belt Drive: Designed for use with cartons that are taller i n height and shorter in length. Belt drives are located above and below the carton. This configuration provides maximum stability since it applies force to the strongest areas of the carton, which is in the direction of the corrugated fluting.
Minimising force is applied while the carton is processing. This style processes the widest variety of carton dimensions but narrow width cartons may be better suited sealers with side belt drives.
