Unwind and Forming:
Two hard chrome plated steel
shafts, mounted on the specially designed structure
at the rear of the machine - one on top and another
on the bottom.. A mechanical breaking arrangement
on the side of each of these two shafts is mounted
to control the tension of the film.
The shafts can be moved horizontally
to fine tune the center of the film.
The film is formed into
a tubular shape with the help of a former which
guides it into a center seal arrangement.
center Seal section with
Gusset Forming Attachment:
The film is formed into a tubular
shape over the former and fed into center seal
arrangement where center seal takes place. This
is followed by center sealed pouch passing through
center seal pressing mechanism to ensure a strong
center seal.
A side gusseting attachment for
center seal pouch, which is a standard attachment,
is provided here.
A set of rollers comprising of
silicon rubber roller on top and a ground and
hard chrome plated steel roller at the bottom
form a nip which is driven by 1 HP DC motor (
Optional 1 HP AC motor ) and pulls the film from
the roll mounted on the unwind shaft/s.
The sealed film is fed into a
pneumatically operated dancing roll mechanism
to maintain continuity and constant tension between
the nip and bottom sealing and cutting mechanism. |
