This type of packaging machine is what known as a sleeve type labeler. These machines are very popular because the two operations of labeling the product container and applying a tamper proof seal are performed in a single operation. A roll of plastic sleeve material which is folded flat like are firehose on a reel is mounted on a hub on the machine. The sleeve is then guided around a plastic wedge block which causes the sleeve film to open up into a cylindrical shaped tube. As the machine runs, the sleeve material is dispensesd one label length at a time. A guillotine knife then cuts it off into a tube that gets deposited into a transporter reel at the 9 oclock postion. The transporter reel indexes to the 12 oclock position and a vertical plunger pushes the open cylindrical sleeve down around the bottle. The bottles are fed into the machine with a timing screw which spaces them out and sychronizes their position to the plunger. After the sleeve is applied, the bottle then travels on a conveyor through a heat tunnel causing the plastic label sleeve to shrink tightly around the bottle.
This time the machine was jamming constantly because the sleeve was being fed down before the guillotine knife retracted out of the way. The operators could not make it work, or repair it. So now it was time to go deep into the system. That's where I come into the picture.
