Unwind and Forming:
A multi option unwind section
comprises of
- 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 - to hold two different film
rolls. 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 centre of the film.
This option enables the
user to make side seal pouches from two different
film rolls.
- A hard chrome plated steel shaft is mounted
on the side of the specially designed structure
at the rear portion of the machine fitted
with mechanical breaking arrangement to control
the tension of the film.
A provision to move the roll
vertically is also provided to fine tune center
of the film.
The film from this shaft is formed
into side sealed pouch by guiding it over a former.
This former can be adjusted to alter the size
of the side seal pouch.
Side Seal section:
The folded film from unwind,
mounted on the side of the specially designed
structure at the rear portion, is fed into the
side seal arrangement where sides are sealed with
the help of a pair of heaters on both the sides
of the folded film.
In case of two separate films
coming from unwind, the films are directly fed
into the side seal arrangement for sealing.
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.
