Technical Implementation |
|
|
|
Soft-running ball bearings support the roll of film as the friction drive unrolls
film from the reel. The splicing device immediately following the roll of film not only
enables the film to be changed, but also minimizes the time required to change rolls. The
bag containing the splice is not filled and is automatically removed. |

The film is pulled over a forming shoulder coated with a low-friction surface
material and formed into a tube. One (1) Continuously heated sealing bar makes the
vertical overlapping seal. Accurate temperature and pressure control ensure uniform seal
quality. |

|
A built-in knife separates a package already filled from the tube. Two (2)
electronically-controlled, continuously heated sealing bars seal the finished package and
at the same time form the bottom seal for the next package. Intensive air-cooling permits
the shortest possible cycle times. |

All functions of the machine are controlled by a Programmable Logic Controller
(PLC). The operation and program management are activated using a color touch screen
display with menu based control. Machine status and messages are displayed graphically and
in plain text. Customized memory settings allow the customer to easily switch to different
size packages. |
