back of the machine. Position the film roll on the rollers and tighten the bolts on the film
rack collars to hold the film roll in position.
Decide whether the film is an A or B wind, and then thread it through and around the
idler rollers and the pin perforator. (See the following illustration.) When threading the
film, make sure to pull excess film through the rollers, across the product tray and into
the sealing area to ensure sufficient film to begin. When you have threaded the film,
separate the top film from the bottom and insert the product tray between the film top
and bottom. Make sure that the center-fold of the film is at the back of the product tray.
This allows the operator to insert product on the product tray between the top and
bottom layers of film to prepare to move the product and film into the sealing area. Do
not place product in the first few bags formed by the sealer: they will not have any
perforation holes in them (because the sealer and pin perforator work together).
Perforation is required to allow air to vacate when the product passes through the shrink
tunnel.
Cradle-Mount Film Unwinder
Begin inserting product into the film as soon as the film reaching the seal area has
perforations in it. Place the product against the back of the film separator tray and then
move product into the seal area. Be sure to leave the bag loose around the product
when making the seal. This helps keep the seals from blowing out in the shrink tunnel.
See Sequence of Operation, which follows, for more detailed instructions for operating
the L-sealer.
