Auto Adjust C-Folder


The Auto Adjust C-Folder is a  single unit, track mounted, dual unwind, folding frame and pin perforator to accept rolls of flat film up to 50 inches wide x 18 inch diameter and feed perforated C-fold film to a winder or packaging machine.

The unit is equipped with dual unwind spindles with friction brakes. The edge of the film is sensed between the payout roll and the folding frame with the position sent to a guiding system with 4 inch travel to consistently track the film to the folding frame, providing edge matching of the C-fold, or offset to provide extended top or bottom lip if desired.

The un-wind and folding frame are manually adjustable to provide tracking of the C-folded film into the winder or packaging machine. The unit may be positioned to feed from the folding frame directly into the winder or film feed of the packaging machine, or may be positioned at 90 degrees to the winder or packaging machine using a turning bar to feed the C-folded film to the winder or packaging machine.

The folding “V” frame is fabricated from steel tubing, with internal air passages and vent holes to provide an air cushion for the film to ride over the folding frame.

The unwind and folder is designed to be easily converted from upstream to downstream film loading, and from right hand to left hand film delivery. The folder has an optional guarded roll with removable shells to accommodate perforator pins which may be configured to provide perforations in any pattern across the film.
