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. |
