4.11 PUNCHES ADJUSTMENT
The number of punches to be used depends on the width of the packets to be packaged. For
small packets, one punch can be enough. In the machines series S440-S560-S560N-S560NA
two punches are available, whereas there are three of them in the S870. It is possible to adjust
the punches (A) at different distances from the contrast (B) by turning the punch (see Fig.
4.11.1); if you decrease the distance, the holes in the film are more marked. A correct position
of the punches allows you to obtain a perfect heat-shrinking, so as to avoid the package tearing
along the sealed side.
4.12 PACKAGING TANK WORKING SURFACE ADJUSTMENT
(S560N and S560NA)
The product carrier motor-driven belt 1 must be adjusted using the handwheel 2 according to
the height of the product to be packaged.
For a good packaging, film sealing 3 must take place at half the product height 4.
