UPPER FILM COIL INSERTION
Insert the coil in its mandrel,
hold the nut and place the reed on the
coil support centred with respect to
the setting rings.
Place the coil on the upper coil
support. The sense of the coil
introduction will depend on which is
the welding face. This face must be
opposite to the lower film (downwards
at mould inlet) for both parts to weld
together. Make the film pass through
the winders according to the scheme.
The upper film has no specific
dragging system. It is driven by the
lower film once they are welded
together.
Insert the film until it reaches
the welding mould inlet or stick it to
the lower film with some sticking tape.
During the first cycle, when you press
the start button, if the welding
temperature is adequate and the
sealing time sufficient, both materials
will weld together and the lower film will drive the upper film, except if one of the coils is
badly placed. If this was the case, check if the welding faces of both films are opposite
each other.
If the upper film is of a printed type, try to insert it so that the printed part is
centred with respect to the sealing.
